深圳城市化过程与水环境质量变化研究

选择深圳这个人类活动强度极大的城市作为案例地区，基于深圳多年的统计数据、环境数据以及影像的解译数据，进行回归和主成分分析，建立了城市化水平与城市水环境质量变化之间的回归模型．结果表明，城市用地比例是深圳河流综合污染指数变化的主要原因，这从另一方面表明，区域环境容量是评价区域环境质量的重要基础，单一强调排放量和排放控制不能全面地反映环境质量变化的原因．

A STUDY ON URBANIZATION PROCESS AND CHANGES OF WATER ENVIRONMENT IN SHENZHEN CITY

Urbanization has already become one of the main means for human to change the earth. The thesis tries to understand the impact of population increase, economic development and land use/cover change in urbanization on the water quality in Shenzhen city with the support of the relatively complete statistical data, environmental data and RS data. Here, a regressive model between the urbanization and water quality change in Shenzhen city is developed. Urban land proportion shows the closest relativity with the water pollution index of the rivers by the multi variables step regression between 5 independent variables. The main conclusion suggests that the regional environment capacity research is the important base of the regional environment assessment and simple emphasis on the control of the letting amount cannot make out the change of the regional environment quality change completely.
