摘　　要：为了更好地配合喀斯特石漠化的综合治理,结合地理信息系统(GIS)和决策支持系统(DSS)技术,采用Map Object开发方法,开发了喀斯特石漠化综合防治空间决策支持系统。充分利用喀斯特石漠化地区各种空间信息,建立石漠化强度现状分析、石漠化发生率计算、石漠化年变化率分析等决策分析模型以及石漠化综合防治效果监测模块。通过实际应用可知,基于空间决策支持系统(SDSS)建立空间信息系统可以很好的为喀斯特石漠化的防治提供决策分析,可以更好地监测石漠化强度的变化,有助于石漠化的治理工作。For better comprehensive treatment of Karst rocky desertification, combined with technologies of geographic information system（GIS） and decision support system（DSS）, spatial decision support system（SDSS） of integrated control of Karst rocky desertification was developed by development means of Map Object. Making full use of various spatial information in Karst rocky desertification regions, decision-making models were established such as analysis of rocky desertification intensity status in quo, calculation of rocky desertification incidence and analysis of annual variation ratio of rocky desertification. Monitoring module of integrated control effect of rocky desertification was also established. Through actual application, establishment of spatial information system based on SDSS would better provide decision analysis for integrated control of Karst rocky desertification and monitoring the rocky desertification intensity variation, which would help to the treatment of rocky desertification.
