【摘要】：在第一次地理國情普查統(tǒng)計數(shù)據(jù)與調(diào)研數(shù)據(jù)的支持下,采取小流域劃分與圩區(qū)劃分相結(jié)合的方法,對德清縣進(jìn)行水環(huán)境空間評價單元劃分。選用畜禽養(yǎng)殖污水排放量、重點企業(yè)污水排放量、農(nóng)藥化肥入河量、城鎮(zhèn)與鄉(xiāng)村生活污水排放量等5個指標(biāo),運(yùn)用GIS空間分析與統(tǒng)計分析方法進(jìn)行水污染負(fù)荷綜合分析,并進(jìn)行壓力類型劃分。嘗試?yán)盟h(huán)境功能區(qū)劃及生態(tài)環(huán)境功能區(qū)劃的既有成果對各空間評價單元進(jìn)行水環(huán)境目標(biāo)類型區(qū)劃分,并將水環(huán)境目標(biāo)類型與其水環(huán)境壓力類型進(jìn)行空間匹配分析,共劃分為7種水環(huán)境脅迫類型區(qū)。此外,對各脅迫類型區(qū)的主要村域分布進(jìn)行了識別。
[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.
