中文摘要：

在第一次地理国情普查统计数据与调研数据的支持下,采取小流域划分与圩区划分相结合的方法,对德清县进行水环境空间评价单元划分。选用畜禽养殖污水排放量、重点企业污水排放量、农药化肥入河量、城镇与乡村生活污水排放量等5个指标,运用GIS空间分析与统计分析方法进行水污染负荷综合分析,并进行压力类型划分。尝试利用水环境功能区划及生态环境功能区划的既有成果对各空间评价单元进行水环境目标类型区划分,并将水环境目标类型与其水环境压力类型进行空间匹配分析,共划分为7种水环境胁迫类型区。此外,对各胁迫类型区的主要村域分布进行了识别。

英文摘要：

Based on the data from the first census of geographical information, Deqing County has been divided into 58 assessment units of water environment space by combining the division of small watershed and polder area. Using spatial analysis and statistical analysis in GIS and choosing sewage production from livestock and poultry, sewage discharge of key enterprises, pesticide and fertilizer input, urban and rural domestic sewage discharge, water pollution load was comprehensively analyzed and water pollution pressure was divided. This study attempted to divide target regionalization of water environment using the outcome of function zoning of both water environment and ecological environment.Meanwhile we conducted a spatial matching analysis by combining water environment target and water environment pressure of each spatial evaluation. Totally, Deqing County has been divided into seven types of water environment risk regions including low-target and low-pressure region, medium-target and low-pressure region, low-target and mediumpressure region, high-target and low-pressure region, low-target and high-pressure region, medium-target and mediumpressure region, and medium-target and high-pressure region, respectively. Then main administrative villages distributed by various pressure and risk regions are identified. This research would improve the pertinence of sewage governance in Deqing County and provide certain reference for guiding industry promotion and spatial distribution.
