太湖水域氮、磷环境容量评价

Evaluation on nitrogen and phosphor volume in Taihu Lake area

最近20年来,太湖水质不断恶化,富营养问题日益严重。有效治理太湖当前污染的前提,是查明太湖的污染因子、途径及环境容量。本次研究从生态地质的角度,以太湖水体中水生植物的组成、生态效应分析为依据、以东太湖输出Ⅲ类水为目标,估算太湖水体的N、P环境容量,对太湖水体环境容量问题作初步的尝试和探索。

In recent 20 years, the water quality in Taihu Lake worsened, eutrophic problem severed, the precondition to control the pollution was to investigate the pollution gene, pollution channel and environmental volume. In light of eco-geology, and based on the water plant composition and ecological effect analyses, the author calculated N and P environmental volume in Taihu Lake area taking class three water output in east Taihu Lake as study object.
