Of City Planning to consider the environmental awareness of energy conservation

[Paper Keywords) urban planning sustainable Development of environment protection and energy road design
[Abstract] the Development of the city urban planning plays a vital role in guiding, but a long time, due to urban planning in environmental protection, energy saving aspects of the limitations of the process of urban Development have resulted in a series of environmentally friendly energy saving problem. This article focuses on energy describes the status of urban environmental pollution based on the proposed main content of environment protection and energy that the city environment protection and energy Development in the vision, sets out urban planning important role in environment protection and energy.

Urban planning is a certain period of time the goal of urban Development and planning, the city is integrated between the Office and also the management of urban construction basis, it is closely related to many disciplines. In recent years, because there is no environmental planning and urban planning and urban construction synchronization implementation of the urban environment has been a certain degree of damage, environmental pollution is worsening, the urban environment can not enter the track of healthy development. Thus urban planning green energy should arouse people's attention.

How environmental considerations in urban planning awareness of energy conservation? This article from the urban development of the environmental problems faced by the pipeline layout and infrastructure, building new buildings and about the status of urban road design, discussion of which city planning should pay attention to the issue of environmental protection energy conservation .

1, China's Cities
1.1 The process of urban development problems facing the environment
1.1. 1 water pollution problem outstanding. Due to urban rapid population growth and industry, the rapid development of a large number of sewage has not been properly processed and discharged directly into water bodies, resulting in water environment has been seriously broken ball. China's water pollution the recent upward trend, there are monitoring data in more than 1,200 rivers, 850 more than the pollution, in the seven major water systems, Liaohe, Haihe, Huaihe River pollution is serious, in the city reaches 138 years of statistics, there are 133 River has been polluted to different degrees. across the country reaches 78% is not suitable for drinking water, 50% of the groundwater is polluted, Xi'an, Beijing and other cities also appeared in many water supply crisis. It is estimated each year due to pollution in China economic losses caused by 400 billion
1.1. 2 Urban air quality worse. The rapid development of industry and transportation as well as extensive use of fossil fuels, the dust, sulfur oxides, nitrogen oxides, carbon oxides, ozone and other substances into the atmosphere, the air quality worse. of air pollution is a "coal smoke" pollution, the national urban air concentrations of total suspended particles generally exceeded the average concentration of 309 micrograms / cubic meter: high levels of sulfur dioxide, a serious pollution in some cities, the northern city average 83 micrograms / cubic meter. air pollution caused by the greenhouse effect and ozone depletion is even more direct threat to human survival.

1.1. 3 Noise nuisance is widespread. Now as China's urban industrial, transportation, and cultural entertainment industry's rapid development, the phenomenon of noise from increasingly prominent, according to state-controlled network of 44 urban monitoring, two-thirds of the country life of urban residents over excessive noise environment, the regional environmental noise equivalent sound level distribution in the 51. 5-65, 8dB (A).

1.2 Urban Infrastructure Development Status
1. 2.1 The following lines cross over the vertical and horizontal road
There is overlapping management, the departments reported that planning is not coordinated, independent of construction funds. Often occurs in the former roads, water, electricity, heat, sewage, communications, followed, respectively, controlled the road to open, resulting in the city every day, destroying roads trenching embarrassment. all kinds of pipelines and the materials are not environmentally friendly, not the economy, often leaking, may not have to destroy the road surface.

1.2. 2 Building residential energy into building almost no consideration
Only concerned about the appearance and structure of the house, pay no attention to energy conservation, so that residential use can be extremely wasteful. Statistical experts, communication building insulation, pipe network system regulation, to improve heat efficiency improvements in three areas, in northern China can reduce heating energy consumption at least 60 % to 70%. Architecture is different from the consumption of goods, is the capital of persistent high levels of consumer durable goods, capital goods or family, and its macro-control needed to proceed from the long-term, from the planning to proceed, pay attention to implementation.

1. 2.3 blindness in road design
Designed to focus only on road widening the road, the road does not consider other supporting facilities and comprehensive environmental design. For example, now when the city widened the road, the original cut down all the trees beside the road, do not re-expand after planting, the original rainwater sewage fill up and so on.

2, urban planning how to display green energy
It is based on the energy crisis of the environment, in recent decades, people gradually realize that the urban planning and the relationship between urban development and began to guide the use of scientific planning of urban construction. Urban environmental planning is an important part of urban planning, it in the city's overall urban planning the nature, scale, direction, based on the status of urban environmental quality based on the analysis developed by the investigation in order to protect the human living environment, reduce pollution, energy conservation as the goal of the planning system. According to China environmental protection should be "insist on economic construction, urban and rural construction and environmental construction synchronized planning, implementation and simultaneous development of economic, social and environmental benefits of harmonization," the general policy and overall strategy, the city should be mainly for protection of the following energy saving work:
2.1 The preparation of urban environmental protection plans, these preparations are the basis for urban environmental planning, which includes information on the city's natural environment, such as geographic location, environment, meteorology, hydrology, etc.; the city's social and economic conditions, such as population, GDP, etc.: a survey of environmental conditions, such as air, water, noise monitoring data, etc.; urban environment of the analysis and functional divisions and so on. reposted elsewhere in the Research Papers Download http://www.hi138.com 2 2. comprehensive improvement of air pollution in urban air quality planning is based on status and trends of development of the environmental function zoning objectives according to functional areas calculated the maximum allowable amount of emissions and reductions, so as to formulate pollution control programs. air pollution control should be based on the city The energy structure of pollutants and traffic conditions to determine that the concentration of high priority, a wide range of harmful pollutants in large, easy to control when targeted to the right medicine. The current air pollution in most cities in China mainly from coal combustion using backward and car exhaust caused by, resulting from the primary pollutants are sulfur dioxide and total suspended particles, so planning should be to improve the vision behind the ene coal methods, improving combustion efficiency, make use of gas fuel, coal, solar, geothermal and other non-polluting or less polluting energy, the implementation of district heating and destroying thousands of families of small chimney to improve the road hardening rate, by strengthening and improving pollution control pollution control technology and other means to create smoke-free control area. adjustment of industrial distribution, atmospheric purification according to laws of science have reasonable use of atmospheric environmental capacity; strengthen the sources of governance, reduce pollutant emissions; through technical and administrative measures to reduce vehicle exhaust pollution; improve the urban green rate, select the anti-pollution and good species, develop plant purification.

2.3 water pollution control planning, water pollution control planning in the Survey and Analysis on the basis of water pollution, according to the receiving waters of the environmental capacity for the maximum allowable emissions and determine the best treatment programs. Current seven major river systems of water pollution on the rise, the scope is expanding, and the Yangtze River, Yellow River, Huaihe River, the Songhua River water pollution in the country in 1996 emissions of industrial wastewater 50.29 billion tons, including 7.04 million tons of chemical oxygen demand, 1,514 tons of heavy metals, cyanide 2457 tons, and arsenic compounds, phenols, oil and other pollutants in the number of tons; domestic sewage accounts for about 24% of the total annual emissions of major pollutants are organic. According to the specific situation of water pollution, water pollution control planning should be adopted reform of the backward production methods, the use of low waste, non-waste technology to achieve cleaner production, wastewater treatment efficiency and high resource utilization, reduce the amount of sewage discharge, construction of effective sewage treatment facilities, the strengthening of industrial wastewater and domestic sewage treatment, and ultimately achieve effective protection of water resources purposes.

2.4 Urban planning process should strictly implement the plan of a pen, the principle of building a map. Various departments in the first place when the laying of the pipeline must be constructed with environmentally friendly energy-saving materials, or not allow for the construction, such as heating the water sector to cancel welded steel pipe, the use of plastic materials not easily corroded pipes, etc., so you can avoid "digging trenches every day" phenomenon.

2.5 construction using new materials, innovative building materials, new walls, doors, windows and roofing materials to improve energy efficiency, indoor ventilation, heating system and other aspects of technological innovation, can protect the indoor air fresh, open windows and doors to avoid wasting energy. In addition, the need to consider the reuse of building materials to reduce construction waste building materials resulting updated. In short, by increasing the level of building life and energy and the rational allocation of planning the layout of the residential building, sustainable architecture, can be more effective, or even times, building a conservation-minded society is an important and efficient way, also reflects the overall urban planning and the importance of energy saving design.

2.6 road design reflects the environmentally friendly energy. In road construction, road side trees, planted in a timely manner after widening, trees and flowers for the role in environmental protection, we all see. In the design of road infrastructure supporting comprehensive utilization considerations, embodied energy. For example, road drainage on the set, it should be a single set of channels should not be connected with the water channel and the corresponding position in the row of tanks set up the rain, so rain and snow can is collected, recycling after rain (snow) water can be used in gardens and road side of the green belt, which will greatly reduce the waste of underground water.

3, Conclusion
In short, Energy and Environmental Design Urban planning considerations, not only saves energy consumption, reduce unnecessary costs, improve the city's taste better for the future sustainable development of cities to provide effective protection.
