摘要:

选取一条典型入滇池河流大河为研究对象,深入调查了大河周边地下水氮污染的状况,并对其时空分布规律及其相关影响因素进行系统分析.结果表明,大河周边地下水三氮污染十分严重,时空分布呈现出一定的变化规律.地下水中三氮含量变化与降雨量、空间位置、地下水位埋深和氮肥施用量等因素相关.

关键词: 地下水, 氮污染, 富营养化, 滇池流域, 大河

Abstract:

Nitrogen pollution of groundwater in a typical catchment was investigated in order to understand the nitrogen contribution from groundwater to the serious eutrophication in Dianchi lake. The characteristics and patterns of temporal and spatial distribution of nitrogen in groundwater were obtained for the typical river catchment in Dianchi watershed. Additionally, four factors controlling variation in the nitrogen concentrations in groundwater, such as precipitation and N fertilizer applications, were indentified.

Key words: groundwater, nitrogen pollution, eutrophication, Dianchi watershed, Dahe river
