发布时间：2019-01-21 18:36
【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。
[Abstract]:With the support of the statistical data and investigation data of the first general survey of geographical conditions, the spatial evaluation unit of water environment in Deqing County was divided by combining the division of small watershed and polder area. Five indexes were selected, such as sewage discharge from livestock and poultry breeding, sewage discharge from key enterprises, amount of pesticide and fertilizer into river, sewage discharge from towns and villages, and GIS spatial analysis and statistical analysis method to carry out comprehensive analysis of water pollution load. And the type of pressure is divided. This paper attempts to make use of the existing achievements of water environment functional regionalization and ecological environment functional regionalization to divide the water environment target types of each spatial evaluation unit, and make spatial matching analysis between the water environment target types and the water environment pressure types. It is divided into 7 types of water environment stress. In addition, the distribution of the main village areas in each type of stress area was identified.
