摘要 区域尺度的生态系统健康评价是生态系统健康评价研究的一个重要发展方向,而景观格局对于区域生态系统健康具有重要意义。根据Rapport提出的活力-组织结构-恢复力(VOR)理论,结合景观生态学理论,构建了区域生态系统健康评价指标体系,以滦河流域的4个市为例,采用综合参数评价模型评价了2008年各市的生态系统健康状况。评价结果表明:承德市生态系统属于一级很健康,秦皇岛属于二级健康,唐山市属于三级亚健康,锡林郭勒属于四级不健康。锡林郭勒生态系统不健康的主要原因是生态系统结构单一,而唐山市是由于过度城市化与沿海工业发展。 The ecosystem health evaluation at a regional scale is an important development direction for evaluating the ecosystem health, and landscape pattern is significant to the regional ecosystem health. An assessment index system of region ecosystem health was established based on the theory of vigor-organization-resilience (VOR) proposed by Rapport and the theory of land- scape ecology. The comprehensive assessment model was applied to evaluate the ecosystem health of 4 cities in the Luanhe River Basin in 2008. The results showed that the ecosystem is very health (level 1) in Chengde, health (level 2) in Qinhuangdao, sub- healthy (level 3) in Tangshan,and unhealthy (level 4) in Xilinguole. The undiversified ecosystem structure is the primary rea-son for the unhealthy ecosystem in Xilinguole, and the reason of weak ecosystem in Tangshan is excessive urbanization and de- velopment of coastal industry.
