中文摘要	人为干预是推动生态系统正向演替的动力,探索人为干预作用于生态系统的影响机制对退化生态系统的改善具有重大意义。以花江石漠化综合治理示范区为例,采用GIS空间分析方法,探索了2000-2010年石漠化治理过程中生态系统健康演变特征,进一步探讨了人为干预对石漠化治理过程中生态系统健康的影响。结果表明:(1)石漠化治理过程中生态系统健康整体上呈改善趋势,病态、不健康和亚健康等级相互转换最为激烈;其中亚健康等级转移最为明显,占总转移面积的38.05%;(2)生态系统健康变化呈时空分异特征,生态系统健康不变区面积所占总面积比例最大,为66.75%,遍布花江示范区绝大部分区域,生态系统健康持续好转区主要分布在石漠化综合治理的村组,局部人为干扰强烈地区出现生态系统恶化或反复多变;(3)不同石漠化综合治理工程对生态系统健康的影响不同,其改善比例依次为:封山育林>坡改梯>经果林>水保林>防护林>人工种草。
英文摘要	Human intervention is the driving force to promote the positive succession of ecological system.To explore the mechanism of human intervention to the ecosystem has the great significance for the improvement of the degraded ecosystem.Taking the demonstration areas of the rock desertification integrated management in Huajiang of Guizhou as an example,using GIS spatial analysis method,we investigated the trend of the ecosystem health evolvement of karst rock desertification controlling process from 2000 to 2010,and deeply explored the main factors influencing the ecosystem health evolvement of karst rock desertification controlling process.The results show that:(1)the ecosystem health presented a trend of improvement in the process of rocky desertification control,Conversion between the morbid,unhealthy and sub-health levels was very intense,among them,the most significance is the level of sub-health,which accounted for 38.05%of the total transfer area;(2)the changes of ecosystem health showed spatial and temporal variation characteristics, the unchanged region of ecosystem health widely distributed in the Huangjiang demonstration area, accounting for 66.75%of the total area,continuous improvement area of ecosystem health mainly distributed in the villages where the rocky desertification control project was carried out,ecosystem heath appeared deterioration or repeated variation in the local strong human disturbance region;(3)the influences of different rocky desertification comprehensive treatment projects on ecosystem health are different,the improvement ratio follows the order:closed forest>slope ladder>planting economic fruit trees>forest for soil and water conservation>protection forests>artificial grass.
