Keywords: ecological garden city; construction; Henan Luoyang

Luoyang is a famous historical and cultural city, is located in the south bank of the Yellow River, the East near the Songyue, West Qinling, tie down south Iraq stands, north Mangshan barrier in Iraq, Luo, Chan, Jian four rivers which runs through the rich natural and cultural resources. To enhance the comprehensive economic strength in Luoyang City, promoting the "three civilizations," the coordinated Development, increasing people's living standards to meet the demand, will require that the improvement of living environment and improve quality of life, while the industrial the Development of the environmental problems also requires the Development and construction of ecological garden city, used to maintain the ecological balance of the environment. urban ecological landscape is the subject of urban construction in China is an important work, directly related to the survival of the city environment and quality of life. green life in the 21st century city, people are polluted city to return to the artificial environment of hate and the desire to embrace nature, must rely on the development of urban ecological garden to resolve.

Luoyang City municipal government has always put the "long history of culture as the basis of science and Technology, culture and education is more developed, modern atmosphere rich and habitable landscape garden eco-city" as the goal of urban construction, the city's residents to mobilize broad participation, and establish implement the scientific concept of development, people-oriented, in pursuit of the harmonious development between man and nature, to improve people's living environment, improve the urban quality.

1, the requirements of building an ecological city
The so-called eco-city is built according to ecological principles of social, economic, natural coordinated development of material, energy, efficient use of information, ecological virtuous cycle of human settlements. An eco-city should have a beautiful ecological environment and efficient investment and business environment and a good living environment [1]. in such a city, the development of any industry must be based on the premise does not damage the ecological balance, all the raw materials and energy are the most reasonable, relatively the most efficient use of, kind of natural, environmental protection as social ethics and code of conduct for people of their own; full of shade the grass, mountains and the urban landscape, nature, human behavior and the combination and mutual coordination.

To build an ecological city, it is necessary to create a beautiful environment, gardening is to improve the ecological environment is an important step [2]. To create eco-city green landscape, it is necessary to further improve the coverage of green space, and also enriching the city's gardens landscape, increase the intensity of planting trees and grass. macro level, urban environment Landscape to selected tree species, more trees, plant the tree, and vigorously carry on the nationwide tree planting activities; in view of the level of the road to large-scale development of green landscape, Green on the Road South New Area, East and West entrances green, the old city with the transformation of the road are uniform green planning and design, highlighting the dominant tree of the green belt (plants) species and landscape features to create rich colors and complex layer of seasonal changes mixed structure; the micro-level community should strengthen the consciousness of exquisite landscape, focusing rich cultural connotation of the landscape, especially in parks and green spaces in the streets, creating "a garden of a feature, all the way to a landscape, a Street spots" in the green new pattern, in this three-level set up on the landscape green space system can optimize the system in the local ecological protection, infrastructure facilities and other functions, and meet the needs of man to nature, coordinate the harmonious coexistence between man and nature relationship , reflects the culture of open space, landscape features and natural is the image of love, aesthetics and spiritual culture and so on.

2 and establishing eco-city development planning and construction management system
Green planning is a leader, is to create a garden city guide, landscape construction and development is an important basis. In order to avoid arbitrariness in green building, blindness, Luoyang City Bureau of Parks in the early 20th century, first developed 90 <<1991 2000 Landscape Development of Luoyang City, PLANNING ">, then issued a <<Luoyang City, green environment PLANNING"> In 1995 May, Luoyang City Bureau of Parks has developed a <<1994 2010 Luoyang landscaping system planning >>. In recent years, and has completed <<Wangchenggongyuan overall planning and scenic PLANNING "> <<Dragon Dongshan Scenic detailed PLANNING"> <<Luopu Park Master Plan and Scenic PLANNING "> <" Urban greening entrance >>.

Preparation of ecological urban planning to guide urban development, urban activities to be gradually incorporated into the construction of ecological city track and in the planning guidance to be effective, orderly improve and upgrade the existing urban economic, social, environmental structure, improve the city ecosystem services, improve the urban regeneration of the system, promoting the existing urban structure, urban function, city management and urban operations shift to eco-city comprehensive. a strong eco-city construction coordination mechanisms, strengthening government institutions in policy direction, planning and implementation and the role of macro-control, explore the establishment of a unified, efficient, orderly and coordinated planning and construction of the ecological system and the comprehensive management mechanism.

3 ecological planning and landscape diversity of plant arrangement
Scientific and rational planning is the foundation for building urban ecological garden [3]. The traditional urban planning and design is often as a subsidiary of the green space system planning, it is only concerned about the contents of the layout of urban industrial structure, leading to inappropriate landscaping can only engage in building space, see the seam insert broken green, green layout is often a lack of ecological indicators, as the function of green space, green space requirements of the production units, the construction is completed in the city after the substance taking into account the body, and its results are often destroyed the natural ecological system, but also destroyed the urban ecological basis for survival, but in any case after the completion of the urban environment does not take into account the modern people's reasonable demands of ecological green space, so the modern urban planning and design must be to protect the natural landscape resources as a basis and landscape planners involved, starting from the overall planning area of the comprehensive analysis of its landscape structure, pattern, natural features and adapt to urban construction, so as to achieve optimal use of green space system as a whole.

In recent years, Luoyang City, insisted that the government organizations, mass participation, unified planning, local conditions, stress practical results of the principle of strict management system for urban greening, scientific organization of green layout, a reasonable demarcation, and ensure the green space, so that film, cable, points combined, by adjusting and optimizing the city's land use structure, full use of existing human and natural conditions, expand the proportion of green space, increasing green space, restore ecological functions and plant diversity.

Plant arrangement is to landscape plant material for scientific, artistic combination of various functions to meet the landscape and aesthetic requirements, and create machine-filled garden of birth Realm. "Diversity lead to stability" is a fundamental ecological principle. Greenland more complex the structure, species more green space system more stable, relatively stable plant community is built on the basis of biological diversity, ecological garden in itself means that biological diversity. Plant is the main and basic ecological garden, monotonous landscape plant species established the maintenance of human loss is unstable; increase per unit area on the green, improving the productivity and ecological benefits of community needs to re-green layer, which is not the diversity of plants can not be done ; the same time, preference should be given to local tree planting types to ensure the survival of Garden Plants.

Urban landscape rich in plant diversity also need to, then fine, then good-looking plants and landscape, if you blindly copy will be tedious. Similarly, the diversity of urban environmental conditions, also need to plant diversity. Complexity of the environmental situation in the city diverse, urban high temperature in summer, need to plant heat-resistant plants; factory pollution, anti-pollution plants need to be planted; water shortage in cities need to grow drought-resistant plants; saline salinity need to be planted plants; green walls and overpasses Climbing plants need to grow rich. In short, to achieve suitable tree, to ensure plant diversity.

4 strengthen the urban greening to improve the urban quality
Landscape ecology is the main city, for the regulation of climate, wind and dust, reduce noise, protect species diversity has an irreplaceable role in [4]. At the same time, the image of the city landscape projects, but also a productivity, a beautiful Garden City, parks and green like a dolphin Pearl, attractive, appealing, cohesion, the most close to the lives of the masses, is practical, but also the best indicator of the functionality of urban greening. Luoyang City tight urban greening create an ecological garden city around this goal, started construction of ecological city, Luo prominence with the construction of urban ecological landscape both sides to play in Luoyang City Luo unique advantage of building an ecological city. Luopu Park has been the public image of the landscape and in the field Visitors praise, ecological advantages highlighted, to continue to improve and perfect a good grasp of the plant to adjust, update and replanting, and enhance the rich plant community, the conservation of wetlands, construction of "Valentine's Island" to further enhance the cultural quality to man and nature in harmony. reposted elsewhere in the Research Papers Download http://www.hi138.com Ecological Management of Urban Landscape 5
5.1 improve plant protection work, and gradually give up the use of chemical pesticides, use of biological and bio-pesticides to control pests and diseases
Ancient forests, insects and plants is the relationship between the food chain, maintains a balance of general reach the degree of damage, thanks to the diversity and mutual restraint between species [5]. Urban garden plants types of relatively simple, if not the protection of pesticides, plant diseases and pests will be completely destroyed. But in recent decades, the use of large quantities of chemical pesticides to control pests and diseases, environmental pollution, soil pollution, groundwater pollution and the destruction beneficial organisms, and gradually raised to pests and diseases biological importance. now among the biological control has become an important part of comprehensive prevention and control. biocontrol has not pollute the environment, the role does not destroy the ecological balance. Therefore, with broad prospects for development. biological control methods include: �� the use of micro-organisms. �� birds, such as the use of beneficial insects. �� the use of biological pesticides. bio-pesticides is to use the principles of insect pest control and use of reproductive hormones control insect pests in a way. by protecting and increasing urban predators, birds, Zhou Nie wasps, nematodes, Bacillus thuringiensis, etc., actually increase biological diversity, to achieve the control effect. ecological garden needs plant diversity, but also the diversity of animals and microorganisms need to birds, snakes, frogs , insects, microbes, these natural enemies, the lack of biological diversity, will lead to rampant breeding of pests and diseases, to the devastating damage garden plants.

5.2 The protection of urban green space conscious
In order to improve the city's ecological environment, should take various measures to protect the landscape results [6]. First, publicity, through newspapers, radio, television and other means to publicize the significance of ecological garden, and constantly educate the public to establish the concept of socialist morality and civilized behavior, promote people to care for green space, protect the green results; while protecting birds and beneficial insects, foster ecological values and ecological ethics, and consciously protect the environment; the second is to carry out various activities to protect the green results, such as launching the "tree adoption, "" love green green color, "" Old Forest ", etc., and received good results, increasing public awareness of preserving green love green; third is to develop urban greening and environmental protection ordinances and regulations to restrain people behavior, gradually, a care for the environment, protect the social atmosphere of green space, building a good social climate and urban environment; fourth is to strengthen the green building of law enforcement personnel, strictly enforce laws and regulations landscaping.

Development from traditional to ecological landscape garden is the general trend of landscape development, it requires us to use modern science and Technology, from environmental protection, behavioral science, ecology point of view to study the environment of urban green space planning, gradually building in the city garden to the city and into the garden of the transition. from the guiding principles, environmental effects on the landscape garden should be comprehensive benefits of the first, mainly of plant landscaping, a large area of ordinary green, protection and development of natural beauty, vigorously develop urban external ecological garden greenery.

Construction of a harmonious coexistence of man and nature, ecological garden city urban development is the rational choice [7]. Harmonious development of man and nature is an arduous and complicated systematic project, not overnight, we must adhere to people-centered, consistently do a good job to create a more suitable people to live and start a good environment to achieve ecosystem healthy development. Facing the new century and new stage of the opportunities and challenges, Luoyang City should continue to adhere to the people-centered scientific concept of development, strengthening regional exchanges and cooperation, continuous learning and absorbing the advanced countries and regions of experience, to further speed up the construction of ecological garden city of Luoyang, in order to achieve the sound development of the ecosystem.
