| 摘 要： | 以生态系统健康、生态系统完整性和湖泊内物质循环为基础,在国内外已有的研究基础上,提出了评价湖泊生态系统健康的方法体系、指标和综合健康指数,评价指标包含外部指标、环境要素状态指标和生态指标,并以滇池为例进行评价.1988年、1994年和2001年,滇池的生态系统健康指数从0 847下降到0 814和0 787,这说明滇池的生态系统健康状况在下降,且已处在一种稳定的富营养化状态.

| Abstract: | Based on the conception of ecosystem health, ecological integrity and substance circulation in lakes, an assessing approach and its indicators are brought forward in this paper. The indictors are consisted of external indicators, environmental indicators and ecological indictors. A comprehensive health index (ICH) is calculated based on the indicators. Also, the ecosystem health conditions of Lake Dianchi in 1988, 1994 and 2001 are assessed using the indicators given in this paper. The ICH in 1988, 1994 and 2001 are 0.847, 0.814 and 0.787, respectively. The results from the case study indicated that the health conditions of Lake Dianchi in past three years have been decreasing and in steady state of the eutrophication. |
