Promote the coordination of land use and ecological response of

Abstract: China's land, especially land use change, land-use issues such as ecological security has become a land management and the core focus of whether the scientific and reasonable settlement of these conflicts, to preserve and maintain the land as well as regional ecosystem ecosystem stability and security, related to the sustainable development of China's socio-economic, and even the entire nation's survival and development to promote coordination of land use and environmental issues are described, designed to promote the rational use of land to provide help. At the same time research in related areas to learn from data.

Keywords: land use, environment, coordination

1 coordinate land ecological building principles

1.1 people-oriented, comprehensive, harmonious principles
Eco-building must build a socialist harmonious society as the basic starting point, people-oriented, so that human beings, human and biological, biological and biological, human and environmental, biological and environmental, social and economic development needs and resources in areas such as supply and demand coherence.


1.2 The principle of ecological suitability of land
Ecological construction should be based on the land's natural attributes, the full consideration of land ecosystem inherent ecological conditions of the various types of land use suitability.


1.3 Principle of sustainability
Ecological construction shall be based on sustainable development, based on the sustainable use of land resources, well-coordinated ecological, socio-economic development and the relationship between land use, taking into account ecological, social and economic benefits, and strive to maximize overall efficiency.


1.4 maintain the heterogeneity of land ecosystem and biodiversity principles
Land ecosystems. Cropland ecosystem, shrub and grass ecosystems such as sub-urban village ecosystem ecosystem is always in time and space uneven distribution, which we call the land ecosystem heterogeneity. Maintain ecological land system heterogeneity is conducive to safeguarding the land ecosystem biodiversity. biodiversity increase community capacity to promote in the balance of the ecosystem due to increased stability.


1.5 the principle of local conditions
Land ecosystems in different regions of the ecological environment factors (such as geology, geomorphology, soil, hydrology, etc.) there are some differences, land ecosystems in space have strict geographical sub-opposite sex, therefore, should be based on ecological differences in local conditions, determine meet local real ecological direction.


2 to promote the coordination of land use and ecological environment-friendly land use patterns

2.1 Construction of small watershed land use patterns Advantages
First, adjust the land use structure as the year the implementation of the comprehensive management of water and soil conservation, land utilization and a corresponding increase in productivity, adjusting land use structure and change the past, a single form of agricultural production, the formation of a scientific and reasonable and consistent with local land-use practice structure.

Second, the adjustment of industrial structure in rural areas through comprehensive and integrated development, improving the industrial structure in rural areas, agriculture, forestry, animal husbandry, the proportion of each industry's output has been coordinated to form a rational rural industrial structure, accelerate local economic development, increase food production, increase farmers' income, improve their living environment, improve their living standards.

Third, improve the ecological environment. By more than 25 of the slope farmland to forests or grassland and soil preparation afforestation of barren hills and ravines, reasonable to implement soil erosion control projects, increasing the area of ​​soil erosion, improve the grass coverage, played a The role of soil and water conservation water conservation, while the increase in vegetation, to improve the micro-climate river basin, to maintain ecological balance play a significant role, it shows that the comprehensive management of soil and water conservation to improve the ecological environment to enhance the role of agricultural potential.

Fourth, ecological and economic development in the production process and the economic activities adhere to the protection of ecological environment and realize a healthy ecological system under the economic development rational distribution of productive forces, deal management, development, protection of the relationship between the development of eco-industrial and commercialization of the economy. ecological and economic development to ecological comprehensive development based on the comprehensive development ecosystem to develop ecological and economic targets, both to control soil erosion, improve the ecological environment, and adequate and reasonable use of natural resources, the development of local conditions farming, aquaculture, processing several operations.

Fifth, investments in technology. During the same time the comprehensive management of water and soil conservation, improved technology penetration, increasing agricultural science and technology, the establishment of technology demonstration, demonstration households, training professional and technical personnel, the introduction and promotion of various types of high-tech agricultural technology, plus support to form a combination of production, supply and support the road.


2.2 Civilized ecological advantages of the village land use pattern analysis
"Civilized eco-village" in agricultural production, both the formation of large-scale production, but also to extend the second and third chain, both to create brand-name products, but also improve market competitiveness, both to agricultural modernization, but also enables the light Hot water soil resources to achieve greater efficiency, both Civilized rural eco-village material Civilization, political Civilization and spiritual civilization and harmonious development of ecological civilization, and to adjust the agricultural structure, develop facilities, agriculture, specialty agriculture, pollution-free agriculture and ecological agriculture, both for rural road hardening and "five random" bad habits, but also the rural landscaping, greening, and biogas purification of the environment, not only embodies the type of urban landscape, ecological, modern positioning of convergence, but also the guarantor of harmony with nature, while agricultural production to be sustainable.

Courtyard economy in addition to its own inherent characteristics, such as: flexible production, has a strong adaptability, low investment, low risk, significant benefits for rural areas to provide new energy, to improve farmers' living environment and so on outside There are many other advantages. efficient use of land resources, to the courtyard, based on the intensive production of goods, make full use of the ground, the floor space development and efficient use of labor and time resources to the courtyard as a base to build the greenhouse in winter season to increase production, full use of space-time and family labor. efficient use of resources generated considerable economic, social and ecological benefits, the conditions suitable for breeding, which cycles, feed utilization. biogas produced high-quality energy, and energy-saving, coal, reducing production costs, effects and residue gas, biogas, providing high-quality fertilizer, livestock manure, can reduce the use of chemical fertilizers in improving soil structure and reduce the cost of crop production, increase crop yield and quality of scientific development concept, high scientific, courtyard economy adapted to local conditions can develop people's initiative, rational use of biological resources, to organize an effective recycling system, so that the primary production by green plants obtained can be repeatedly recycled bio, thereby enhancing the agriculture, ecological and economic benefits.


3 to promote the coordination of land use and environmental measures

3.1 to adjust land use structure, the implementation of ecological planning
Implementation of the "treasure and rational use of every inch of land" principle, various types of intensive land use and management, and strive to improve resource utilization and productivity of land, efficient land use of the best economic, social and ecological principles of comprehensive benefits. from the actual situation of soil erosion are more serious, should vigorously carry out vegetation protection, restoration and reconstruction work, take the small valley artificial tree planting, grass and farmland protection forest construction methods to improve the regional vegetation coverage . construction of small watershed as a unit of environmental management demonstration area, supplemented by some of the works of local measures, including dams, levees, etc., give full play to biotechnology and engineering measures the overall efficiency.


3.2 strictly implement farmland protection policy to improve the quality of agro-ecological environment
Protection of cultivated land, especially basic farmland protection is to safeguard the ecological security an important task and we situation is the large number of arable land, basic farmland and more, a large population base, resulting in per capita arable land, but in recent years, the number of occupied land is quite large, and should rise to the leadership attaches great importance to this end, first, to implement the strategy of the dynamic balance of cultivated land, land development, sorting, reclamation measures, timely additional land, and secondly, to increase the material input, scientific fertilization, to prevent land degradation and improve land productivity, improve crop yields, again. to increase financial and technical inputs to improve conditions for agricultural production, irrigation, drainage, anti-early, in addition to stains, the transformation of low-yield fields and improve land quality, we must control of farm pollution, protection of agricultural ecological environment, prevent and prohibit the use of contaminated irrigation water, as little as possible with or without highly toxic, high residue of pesticides, insecticides and herbicides, development and utilization of low toxicity and residue and efficient pesticide , bio-pesticides and bio-degradation agent, to promote integrated pest management measures to improve farm infrastructure, vigorously promote water-saving cultivation techniques to reduce the fat, drug wastage, improve fertilizer drug utilization. to reduce agricultural pollution, enhance the environmental quality of agricultural land.


3.3 The establishment of ecological construction, environmental protection and economic mechanism for integrated decision-making
Rational land use decisions, it is necessary to ensure rapid economic development of the necessary land for construction, especially in key project construction land, but also to protect arable land and basic farmland, in order to achieve protection of the ecological environment of regional development projects in the evaluation of ecological security evaluation is a challenging research topic, which in addition to the complexity of the ecosystem itself, but also by their own gaps in knowledge and understanding of human boundaries. environmental impact assessment, refers to the implementation of regional planning and construction projects after the environmental impact analysis, forecasting and assessment, to prevent or mitigate adverse environmental impacts of policies and measures for tracking and monitoring method and system, therefore, the establishment of ecological construction, environmental protection and economic decision-making mechanisms can be effectively integrated to promote coordination of land use and ecological environment.
