钱塘江(杭州市)水域水质改善控制对策研究

Study on Water Quality Control of Qiantang River Watershed

2009年至2011年期间杭州市环科院以钱塘江水质监测历史资料为基础,采用理论分析、现场观测与调查、GIS和RS等技术手段,融合生物学、生态学、水文学、水力学、水化学等各学科的研究方法,综合分析钱塘江水域生态表征的物理、化学、生物学动态生态过程和调控作用,力图掌握钱塘江水域生态系统的动态变化规律和关键影响因子等,为十二五期间钱塘江流域的水污染防治、保障饮用水源安全提供科学依据。

Based on data collected by Hangzhou Academy of Environmental Science during 2009 to 2011, this paper conduc- ted a comprehensive water quality control study on Qiantang River Watershed, in which theory analysis, traditional on - site moni- toring, modem GIS, RS and mathematic modeling and other technological tools were adopted. In the above - mentioned study, this paper analyzed the physical, chemical, ecological, hydrological characteristics of water from Qiantang River. The study aims to discuss the dynamic variation and key factors affecting the whole ecosystem of Qiantang River and then provides the policy and technology suggestions for the recent water pollution control and drinking water protection in the Qiantang River Watershed.
