The results show that the non-agricultural land increased rapidly, especially the urban and rural residential spots and industrial and mining （RIM） land use increased mostly rapidly, an increase of 64%. Meanwhile, the intensity of land exploitation was accelerating, land was transformed to industries with better benefit and areas experiencing faster urbanization process. By analyzing the harmonious degree of land exploitation in economic and environmental aspects, we find out that the land use imbalance mainly existed in the municipal area of Xi＇an, and the imbalance index of land use based on GDP and non-agricultural population were respectively 12.37 and 14.67 in 2000, which were far higher than those in other regions. Nevertheless the environmental harmonious degree in the municipal area of Xi＇an ranges between 0.6 and 0.8, which was better than that of suburban area. Some proposals addressing to the problems of harmonious level in all scales, resources utilization, projects management and feasibility analysis and intensive urbanization are also put forward.展开更多

[ Method] Based on the concept of ＂healthy lakes＂ analyzed deeply, the fuzzy integrated evaluation was used to establish the evaluation index system of lake health, and the analytic hierarchy process （AHP） com- bined with expert evaluation method was used to determine the weight of each indicator. Afterwards, the health state of three typical lakes （ San- baidang, Beimayang and Qiaobeidang） in Wujiang City were evaluated by the system, and the measures to develop and protect the lakes were put forward finally. E Resultl The assessment results showed that Sanbaidang and Beimayang were in basic health, while Qiaobeidang was in sub- health. The indicator system and assessment method are suitable for the rivers in eastern plains of China.[ Conclusion] The research could provide scientific references for the development, protection and restoration of lakes.展开更多
