Along with the highly speedy urbanization and the industrialization in china,the disordered land utilization has led to land overuse and ecological destruction. However,the city planning and ecosystem protect planning have grown according to rules oneself. the contradiction between economic growth and ecological protection is more evident than ever before. The ecological feasible space for urban development was established based on GIS methodology,combining an ecological function regionalization approach and a economic development feasibility analysis technique. Accordingly,urban spatial structure could be divided into four types,consisting of forbidden construction zone,restricted construction zone,preferential construction zone and primary construction zone. The integrated method for a case study on Jiulongpo district,Chongqing showed that the areas of these four categories of Jiulongpo accounted of 15. 54%,24. 14%,12. 95% and 47. 37% respectively. Demonstrational analysis shows that the essence of urban planning founding on ecological priority benefits to natural reconstruction and reservation;the spatial layout based on the ecology analysis safeguards the healthily and sustainable development of city ecosystem. The methodology was valuable for reducing ecological risks and environmental impacts of urban master plan,and thus was relevant for promoting the national campaign of strategic environmental assessment. The study was guide to city planning and ecological protection planning.
