Abstract：Research purposes：Planning analysis is the basis for  environmental impact analysis, prediction and evaluation of the Planning Environmental Impact Assessment (PEIA), especially  analysis of planning and coordination is the key point. On the occasion of "Technical Guidelines Master of Planning Environmental Impact Assessment " is promulgated, based on the collection of a lot of detailed current situation data, as an example of the intercity railway network plan of Guanzhong City Group, this paper systematically studied  the planning analysis of PEIA, which can be a reference for the railway network PEIA.
Research conclusions：Through analysis of the PEIA, we can drawn  the following conclusions: (1)Using the analogy method, overlay method, scenario analysis method and so on, the environmental capacity in the planning area of the intercity railway network is identified. (2) From the data collection and field investigation in the planning area, it shows that the key environment and resource factors, which restrict the intercity railway network planning and implementation, are land resources, ecologically sensitive areas, water resources, artifacts, rare and endangered animals and plants, and so on. (3) The coordination between the railway network planning and other relevant planning are analyzed, which is relied on many different sights, for example planning and resource conservation, the coexistence of the environmental protection and urban development coordinating, and so on. The impacts of inter-city rail network on the national policies, planning, and regional planning are clear. (4) The analysis of the planning uncertainty is given to ensure the scientific conclusions.（5）The research results can be a guidance and reference in the intercity railway network planning and also have positive references for  environmental impact assessment in the similar railway network plan.
