摘要：

健康的生态系统为实现区域可持续发展提供了基础。采用生态系统健康的理论和方法对区域生态系统健康评价,将对强化生态环境管理和实现可持续发展具有显著的理论和实践意义。本文在RS和GIS支持下,利用多源、多时相遥感影像数据,以小流域为评价单元,初步建立了秦皇岛地区生态系统健康评价的压力-状态-响应概念框架的指标体系和评价模型,并利用现代数学分析方法对生态系统健康状态的变化进行驱动力分析。

关键词: 生态系统健康, 评价体系, 驱动力分析, 秦皇岛地区

Abstract:

A healthy ecosystem provides a fundamental basis for the realization of regional sustainable development.Using the theory and technique of ecosystem heath to estimate area ecosystem health will possess rather good significance in theory and practice for eco-environmental management and regional sustainable development.Based on RS & GIS technology,using the integration of multi-source and multi-period data and micro-catchment estimation section,this paper sets up an integrated assessment index system and assessment model with the concept of PSR（press-state-response）,and accomplishes driving force analysis of regional ecosystem health state change by representative correlation analysis technique. Qinhuangdao area,situated to the northeast of Hebei province,covers an area of about 7812km².The assessment result showed that: the area of the first grade subarea of the ecosystem health state（very healthy state） is 1176.68km²,making up 15.08% of the total area of Qinhuangdao;the area of the second grade subarea（healthy state） is 1930.77km²,being 24.71%;the third grade subarea（sub-healthy state） is 1937.35km²,or 24.79%;the fourth grade subarea（non-healthy state） is 1805.47 km²,or 23.11%;and the fifth grade subarea（morbidity state） is 961.90 km²or 12.31%.The analysis of pattern of ecosystem health state from land use structure showed that the health state of woodland and grassland was the best,the health state of plantation was diverse for some acting factors.There are many forces acting on the changes of the ecosystem heath state such as adjusting industrial structure,distributing productivity reasonably,developing primary industry,applying fertilizer properly,controlling soil erosion and so on. The sticking point in this article was the selection and quantification of the ecosystem heath assessment index system in terms of ecological state,vigor and resilience with remote sensing data,GIS technique and landscape ecological indexes,so as to provide guidance for ecosystem heath assessment research in other districts.
