| 摘要: |
| 湖泊生态系统健康包含两个方面的内涵:满足人类社会合理要求的能力和湖泊生态系统自我维持与更新的能力.获知湖泊生态系统健康状况及其区域分异特征,对于湖泊管理具有重要意义.本文基于对太湖的野外调查,计算了表征湖泊生态系统健康的系统能、系统能结构、生态缓冲容量和湖泊营养状态指数.聚类分析结果表明,太湖不同湖区生态系统健康状况存在一定差异,东部湖区较好,西部湖区较差,呈现由东南部湖区向西北部湖区递减的趋势.该结果对进一步研究湖泊生态系统健康评价指标阈值具有重要的参考意义. |

| Abstract: |
| Ecosystem health is a new field in ecology and environmental management and it is about fostering a new integrative science. Lake ecosystem health refers to a state of a lake both supplying services for people and maintaining its function and complexity. Assessmenl on lake ecosystem health is the basis of lake environmental management and ecosystem control, so it is important to learn the ecosystem health and spatial differentiation characteristics of a lake. In this case study for Lake Taihu, a large shallow eu-trophic lake, an attempt to apply exergy, structural exergy, ecological buffer capacity and trophic state index to the assessment of the lake ecosystem health was presented. The results revealed there was different ecosystem health to some extent in each area of Lake Taihu through cluster analysis. The ecosystem health of East Lake Taihu was the best among the different areas of Lake Taihu. The ecosystem health of the east part near ihe bank and Lake Gonghu was better. The ecosystem health of the center part and the west part of Lake Taihu was worse. That is to say, the ecosystem health of the east part was better than that oi the west part in Lake Taihu, and moreover, the ecosystem health in different areas of Lake Taihu descended from the southeast part to the northwest. The results will give some advice for environmental management of Lake Taihu and can be used to set up the standard for evaluating ecosystem health of shallow eutrophic lakes. |
