【摘要】 生态系统健康是生态学和环境管理方面一个新兴的多学科综合性研究领域。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和湖泊生态系统自我维持与更新的能力。湖泊生态系统健康评价是湖泊环境管理和生态系统调控的基础。运用Exergy、结构exergy和生态缓冲容量等指标来评价太湖梅梁湾湖区2001年生态系统健康的周年变化,其健康状况由好到坏依次为3～4>1～2>11～12>9～10>5～6>7～8月份。这和分别应用营养状态指数(TSI)和生物多样性指数(DI)进行评价的结果相似,表明运用Exergy、结构exergy和生态缓冲容量指标对湖泊生态系统健康状况进行评价的方法是可行的。更多还原

【Abstract】 Ecosystem health is a new field in ecology and environmental management.Lake ecosystem health contains the capability of supplying services for people and maintaining its function and restoration.Assessment of lake ecosystem health is the basis of lake environmental management and ecosystem control.Exergy(Ex),structural exergy(Ex(st)) and ecological buffer capacity(β) were applied to the ecosystem health assessment of annual variation at Meiliang Bay ecosystem.The health state of Meiliang Bay ecosystem in 2001 decreased as the following order: March to April,January to February,November to December,September to October,May to June,and then July to August,which was similar to those estimated by trophic state index(TSI) and diversity index(DI).Therefore it is feasible to use exergy,structural exergy and ecological buffer capacity to evaluate the health state of lake ecosystem.更多还原
