摘要
根据喀斯特生态环境系统的演变过程及其引起石漠化灾害的成因,通过监测预警评价因子,确立了喀斯特石漠化监测预警评价指标体系。该系统依据空间信息和属性信息,在石漠化发展趋势的基础上设计了喀斯特石漠化监测预警系统,利用GIS技术与数学模型,在计算机语言环境下进行了编译,可对生态系统和各种资源环境问题及时地进行监测预警分析,研究结果可为生态系统的良性循环提供辅助决策支持。
According to the evolution of karst ecological environment system and the causes of rocky desertifi- cation disaster, this study established karst rocky desertification monitoring and pre-warning evaluation index system. According to the spatial information and attribute information, this system was designed based on the development trend of rocky desertification. GIS technique and mathematical models, combined with com- puter programming were employed to establish the karst rocky desertification monitoring and pre-warning evaluation index system. The established system can be used to monitor and predict environmental issues in time. It will provide supports to governmental decision making.
