摘要:生态系统健康评价是当前宏观生态学与生态系统管理研究的热点问题之一,区域尺度的生态系统健康评价则是生态系统健康评价研究的一个重要发展方向。在探讨生态系统健康时空尺度特征的基础上,明确界定了区域生态系统健康及其评价等相关概念,结合目前区域尺度生态系统健康评价的相关研究进展,从评价的区域类型、目标单元、模型方法、指标选取及其阈值、权重设定等方面探讨了区域生态系统健康评价的基本原理与方法,并展望了进一步研究的重点方向,即评价结果的多尺度综合与尺度转换、景观生态学理论与方法的应用、3S 技术的综合应用等理论与技术问题。

Abstract:The evaluati on for ecosystem health is one of the hots pots within the fields of macr o ecol ogy and ecosystem management .Conducting analysis at the regi onal scale is an i mportant directi on for evaluating ecosystem health .Changing the spatial scale fr om the l ocal to the regi onal level leads to great differences in the targets and methodologies for evaluating ecosystem health and creates a new directi on for regi onal ecosystem health research .Compared t o ecosystem health at the local scale,which refers to a single ecosystem type,regi onal ecosystem health focuses on the health conditions and s patial patterns of different ecosystem types .However,there is little attenti on t o this very research .Based on the p r ogress on ecosystem health research at the regi onal scale,the study reported in this paper ai m s to discuss the i mp licati ons of the concep t of regional ecosystem health and to put for ward a methodology for evaluating regional ecosystem health .The main results are as follows:(1)there is a significant scaling effect on the ecosystem health analysis and the regional level is the key scale used to focus on the correlation bet ween s patially neighboring ecosystem s in ter m s of ecosystem health;(2)regi onal ecosystem health can be defined thr ough these four as pects,i .e .vigor,organization,resilience,and ecosystem service function;(3)the basic object of the evaluation for regional ecosystem health is s patial entity,which is the matrix of different ecosystem types;(4)the index system method is the only app r oach for evaluating regional ecosystem health;(5)the abs olute thresholds of the evaluation indices for regional ecosystem health do not exist;the ai m of the evaluation is to discuss the temporal change and s patial differences of health conditions and not to ascertain whether a region is healthy or
