【摘要】 石漠化是喀斯特地区特有的土地退化问题,是地质、地貌、植被、土壤、降水等自然背景因素和不合理的人类活动综合作用的产物。喀斯特石漠化已成为农村生态环境建设和经济社会发展所面临的一大难题。地理信息技术在喀斯特石漠化现状调查、防治规划编制等方面得到广泛地应用,积累了大量石漠化地区空间信息和社会经济信息。喀斯特石漠化综合防治空间决策支持系统(KSDSS)是结合地理信息系统和决策支持系统,利用Visual Basic开发软件与MapObject控件开发的建立村一级管理分析系统和土地图斑类别、面积查询分析系统,并根据目前已颁布的国家标准(GB)相应编码数字化,有较强的多媒体数据和矢量数据库管理功能。它是以贵州省毕节鸭池示范区的基础信息及石漠化决策信息为数据源、以有助于实现喀斯特石漠化综合防治为目的、以GIS分析方法、决策支持和软件开发技术为手段开发的GIS应用系统。喀斯特石漠化综合防治空间决策支持系统(KSDSS)的开发对喀斯特地区石漠化治理将发挥其决策支持的作用。系统引入实时、高分辨率遥感数据作为系统重要数据源并融合决策支持系统(DSS)的多模型组合建模技术与地理信息系统(GIS)空间分析技术。系统包括两个主体,一个是模型库与数据库的结合,它是决策支持的基础,为决策问题提供定量分析(模型计算)的辅助决策信息;另一个是人机交互,它是地理信息系统与决策支持系统结合,是用户与计算机的交互界面,包括信息查询、模型计算、模型查找、空间分析等。更多还原

【Abstract】 Rocky desertification is unique land degradation problem in the karst area, which is the combined action product of such natural background factors as the geology, the landform, the vegetation, the soil, the precipitation and the unreasonable human activity. The karst Rocky Desertification has become a big difficult problem which the countryside ecological environment construction and the development of the economy and the society have to face. The geography information technology is used widely in the aspects of the present situation investigation, control program about the karst Rocky Desertification and has accumulated massive spatial information and the social economy information of the rocky desertification area.The space decision support system of the karst rocky desertification(KSDSS) integrated control combines the geographic information system and the decision support system, is the village-level management analysis system and the plat spot category, the area inquiry analysis system ,which using the Visual Basic and MapObject controls , Who accords the present national standards to digitize and has strongly administrant function of the multimedia data and the vector data base. It is the GIS application system,who takes the foundational information and the rocky desertification decision information of the Yachi model district in Bijie Guizhou as the data resources and with the purpose of controlling the karst rocky desertification integratedly and with the GIS analysis method , the policy-making support and the software development technology.The development of the space decision support system of the karst rocky desertification(KSDSS) integrated control will play a role of policy-making support for the manage of the karst area Rocky Desertification. The system introduces real-time and high definition remote sensing data as the important data resources, making use of the multi-model combination modeling technology of the decision support system (DSS) and the geographic information system (GIS)spatial analysis technology. The system includes two main parts. One is the combination of the model base and the database which is the foundation of the policy-making support providing the auxiliary decision information of the quantitative analysis (model computation) for the policy-making; The other is the man-computer interaction, which is the union of the geographic information system and the decision support system and the interactive windows between the user and computer, including information inquiry, model computation, model search, spatial analysis and so on.更多还原
