摘要
首先运用"图谱"表达方式和GIS分析工具,分析喀斯特土地石漠化征兆图谱和诊断图谱,以都安瑶族自治县为例监测喀斯特土地利用/覆盖变化及其引起的石漠化时空演变规律及驱动机制;在此基础上,归纳广西喀斯特土地石漠化的4种生态重建模式,剖析各种模式的生物和工程等具体措施,为喀斯特石漠化区域环境治理与可持续发展提供科学基础和个案分析。
With atlas and GIS, symptom atlas and diagnosis atlas of karst land rocky desertification were analyzed. Taking Du'an Yao autonomous county as a case study area, spatial and temporal evolution rule and driving mechanism of karst land use/land cover change were analyzed. On the basis of those analyses, four ecological rehabilitation models of karst rocky desertification in Guangxi Zhuang Autonomous Region were concluded and biological and engineering measures of every ecological rehabilitation model were discussed, which provided scientific basis and case analysis for the environmental reconditioning and sustainable development of karst rocky desertification areas.
