According to the 《People's Republic of China environmental protection law》 , 《People's Republic of China 》 《 the law of environmental impact assessment》, planning Environmental Impact Assessment Ordinance requirements, in order to prevent decision source of environmental pollution and ecological destruction, and promote economic and social comprehensive coordinated and sustainable development of the environment, to carry out the planning environmental impact assessment.
       The planning EIA is applicable to the relevant departments of the State Council, the municipal organization of local people's governments above districts and the relevant departments of the land use planning, regional, watershed area, construction, development and utilization, as well as industry, agriculture, animal husbandry, forestry, water conservancy, energy, transportation, city construction, tourism and related special planning the development of natural resources. And the relevant departments of the State Council, the Municipal People's governments above districts and relevant departments to organize other types of planning, people's government at the county level for planning.
       Through the planning environmental impact assessment, to provide resources and environment information planning and decision making, planning and implementation of the main identify constraints resources (such as land resources, water resources, energy, mineral resources, tourism resources, biological resources, landscape resources and marine resources) and environmental factor (such as water environment, atmospheric environment, soil environment marine environment, sound environment, and ecological environment), determine the environmental objectives, analysis of building evaluation index system, and on regional, watershed planning implementation evaluation and prediction, the overall impact of the marine ecosystem, the long-term impact on the environment and human health from the demonstration plan for sustainable and environmental rationality The influence of sustainable development, accessibility demonstration planning and implementation of environmental objectives and targets, planning optimization proposal, put forward the Countermeasures for protecting the environment, coordination measures and tracking evaluation plan, planning the implementation of the relationship between economic benefit, social benefit and environmental benefit as well as the current interests and long-term interests, to provide decision-making basis for planning and environment management.
       In the outline of the plan for the preparation stage, through the analysis of the planning may involve the contents of the collection and planning of relevant laws and regulations, environmental policy and industrial policy, carry out field investigation on regional planning, collecting basic data, the investigation of environmental sensitive areas, the main environmental recognition planning implementation, put forward implementation of the plan resources and environmental constraints, feedback to the planning authorities. At the same time to determine the environmental impact assessment of planning scheme.
       In the research phase of planning, planning evaluation with in-depth, timely implementation of different planning of resources, environment, ecological impact analysis, prediction and assessment, reasonable comprehensive demonstration of different planning schemes, puts forward optimization suggestions, feedback to the planning and preparation for the authorities in different planning schemes than the selected reference with the use of.
       (1) in the preparation stage of planning:
              a) should be aimed at environmental impact planning environmental assessment recommended feasible, an environmental impact from the strategic and policy level mitigation measures. If the plan fails to adopt project environmental impact assessment recommended, should also put forward the necessary adjustments to optimize the plan. The tracking system of EIA project, put forward the requirements of environmental management. Feedback to the planning authorities.
              b) if the scheme of resource and environment planning selection can not carry, may cause serious adverse effects on the environment and to put forward feasible preventive countermeasures and measures or mitigate adverse environmental impacts, and to the possible extent or scope is still unable to make scientific judgment, should give up the planning advice, feedback to the planning authorities.
       (2) in the planning approval should be completed before the book report on environmental impact of planning (planning environmental impact text or instructions) to write and review, and submitted to the planning authorities.
