构建了以活力、组织水平和弹性恢复力为主要指标的评价体系,建立了人工垦复——竹林生态健康关系模型:Y=0.802 064 016-0.023 261 585 034 X12-0.028 516 085 034 X22,并结合湖州市的竹林特点进行分析,结果表明:随着坡度的增加,健康状... 构建了以活力、组织水平和弹性恢复力为主要指标的评价体系,建立了人工垦复——竹林生态健康关系模型:Y=0.802 064 016-0.023 261 585 034 X12-0.028 516 085 034 X22,并结合湖州市的竹林特点进行分析,结果表明:随着坡度的增加,健康状况整体下降,随着竹林不科学的经营人为干扰的增加,抵抗外界干扰的能力降低;将毛竹林生态系统健康状况划分为3个类型:健康类型、健康状况一般的类型、健康状况较差的类型,人工垦复与立地坡度对森林健康有负影响;以面积比例为权重,湖州市毛竹林的管理水平指数为1.557 175,要实现湖州市毛竹林健康管理,竹林建设的坡度指数应不大于1.483 137,对应的坡度为27.415 69°,也就是说,保障湖州市竹林生态系统,发展竹林的立地坡度不适宜高于27.4°。 展开更多

Strategic environment assessment (SEA) and ecosystem health are two new ideas on environmental management. On the basis of reviewing some relevant literature, this paper made discussions on the ecological sustainability target of SEA, the content of ecosystem health as well as the interrelations between SEA and ecosystem health. For a good SEA, its ecological sustainability principles should be provided with distinct content and a general assessment system. A framework for ecosystem health assessment was established according to the content of ecosystem health, and combined into SEA as SEA抯 ecological sustainability target, we can effectively guide decision-makers to make suitable indigenous means and local solutions. , The basic principles and procedure of SEA for ecosystem health are also discussed in the paper. 展开更多
