喀斯特石漠化地区生态系统健康是生态建设和石漠化综合治理的目标，以贵州省花江石漠化综合治理示范区为例，运用遥感影像解译方法，结合社会调查与水文气象监测数据，从生态环境支撑系统、资源环境支撑系统和社会经济支撑系统三个方面，构建石漠化治理过程中生态系统健康变化诊断指标体系，在格网GIS 技术支持下，对各诊断指标实现5 m×5 m 尺度的网格化表达，运用栅格数据的空间叠加方法实现生态系统健康模型诊断，揭示石漠化治理过程中生态系统健康的时间动态与空间格局。结果表明：(1)花江示范区生态系统很健康的区域不存在；(2)近十年来，花江示范区生态系统健康整体状况有所改善，石漠化综合治理取得一定成效，但整体上仍然以不健康和亚健康的区域为主，占区域总面积78.68%；(3)空间上呈现出区域差异的特点，示范区东北部海拔大于1000 m 的峰丛陡坡上生态系统健康状况较差，峰丛洼地区生态系统健康状况则相对较好。
喀斯特石漠化地區生態繫統健康是生態建設和石漠化綜閤治理的目標，以貴州省花江石漠化綜閤治理示範區為例，運用遙感影像解譯方法，結閤社會調查與水文氣象鑑測數據，從生態環境支撐繫統、資源環境支撐繫統和社會經濟支撐繫統三箇方麵，構建石漠化治理過程中生態繫統健康變化診斷指標體繫，在格網GIS 技術支持下，對各診斷指標實現5 m×5 m 呎度的網格化錶達，運用柵格數據的空間疊加方法實現生態繫統健康模型診斷，揭示石漠化治理過程中生態繫統健康的時間動態與空間格跼。結果錶明：(1)花江示範區生態繫統很健康的區域不存在；(2)近十年來，花江示範區生態繫統健康整體狀況有所改善，石漠化綜閤治理取得一定成效，但整體上仍然以不健康和亞健康的區域為主，佔區域總麵積78.68%；(3)空間上呈現齣區域差異的特點，示範區東北部海拔大于1000 m 的峰叢陡坡上生態繫統健康狀況較差，峰叢窪地區生態繫統健康狀況則相對較好。

Ecosystem health is the goal of ecological construction and comprehensive treatment of rocky de-sertification.Taking the demonstration area of rock desertification integrated management in Huajiang of Guizhou Province as an example,this work uses interpretation of remote sensing images,combining social investigation with hydrological and meteorological monitoring data,to establish a set of indicator frameworks for ecosystem health in such three aspects as the support system of natural resources,the support system of environment and the support system of society and economy.With support of the gridding GIS technology, this study gives each index in the diagnosis system the spatial expression of a 5 m×5 m grid scale.Subse-quently,using the spatial overlaying technology based on grid data,we reveal the temporal dynamics and spatial pattern of ecosystem health huring the karst rocky desertification integrated management.The re-search results show that no area of good health exists in the Huajiang demonstration area.In the past 10 years,although the ecosystem health has been improved to some extent overall,most of the land remains unhealthy or sub-healthy,which accounts for 78.68% of total area.Regional differences appear in spatial distribution.The ecological system of peak cluster-depression is more healthy than the peak cluster steep slope,which is located in the northeast of the Huajiang demonstration area (higher than 1000 m above sea level).
