官厅水库氮、磷污染及其控制途径

官厅水库是北京地区担负多功能的重要水资源。过去曾对该水库的酚、氰、重金属污染做了许多调查研究。但很少涉及氮、磷污染问题。本项工作主要对该水库近年来氮、磷污染水平、污染的生态效应特别是富营养化问题,进行了较为系统的研究,根据实验结果进行了综合评价。在此基础上,应用生态学原理,提出了控制氮、磷污染的有效途径。

NITROGEN AND PHOSPHOROUS POLLUTION OF GUANTING RESERVOIR AND THE WAYS OF CONTROL

Guanting Reservoir is an important water supply with multiple functions in Beijing area. There had been carried out many kinds of interesting investigation about pollution evaluation by phenol, cyanide and heavy metals etc., but little information concerning N and P pollution obtained.This paper is written with recent studies on N and P pollution of the reservoir, their ecological effects particularly of eutrophication, and then a comprehensive evaluation about N and P of the reservoir was made. Results obtained are to be used to make some suggestion about effective ways of pollution control of the reservoir on basis of ecological rules.
