抚仙湖流域生态系统结构与功能分析

从湖泊地质结构、湖泊水文、湖泊生态系统的不稳定性、湖泊水环境承载能力特征进行了分析，结果表明：抚仙湖的生态系统不稳定，水环境的承载能力有限，湖水补给水量较小，水资源消耗量大。湖泊的功能是由各种资源相互作用而维系的，直观的资源过度利用造成对其功能的危害。全面实施抚仙湖保护，成为关系玉溪市社会经济可持续发展的头等重大问题。必须实现湖泊资源利用和经济的可持续发展，保护湖泊的生态服务功能，确保湖泊的生态安全。

Analysis of Ecological System Structure and Function in Fuxianhu Lake Basin

Based on analyzing geological structure and hydro and instability of ecosystem and water environment loading capacity of Fuxianhu lake, the results show that the ecosystem of the lake is instable, and the water environment loading capacity is limited with small water quantity supply and large water resource consumption. The extreme water resource utilization leads to the destruction of lake function. To protect Fuxianhe lake becomes the key issue to remain sustainable development of society and economy of Yuxi.
