| 摘 要： | 基于TM影像解释和实地考察,查清了罗甸县石漠化面积为103479.65 hm2、占全县土地总面积的34.35%,划分了石漠化强度(中度以上的石漠化面积占全县总面积的15.83%),明确了罗甸县石漠化的空间分布格局,分析了罗甸县石漠化的危害。根据石漠化现状及分布,其防治分区以流域、主要地貌类型、石漠化程度及防治方向、区域资源条件为划分依据,并采取二级分区等级系统将石漠化综合防治分为4个大区(其中包括11个小区),并对此提出综合防治对策。

| Abstract: | Based on TM imagine and field investigation,it was analyzed that the rocky desertification area of Luodian County was 103 479.65 hm2,occupying 34.35% of the total land area of the county.The rocky desertification degree was divided(the area above middle degree rocky desertification is more than 15.83% in the total land area of the county).The spatial distribution pattern of Luodian County was made clear,and the damage of rocky desertification of Luodian County was analyzed.According to the status and distribution of rocky desertification,its control subarea and river basin,major geomorphological types,rocky desertification degree and control direction,regional resources condition were used as the partitioning standards.Comprehensive control of rocky desertification was classified into 4 big areas and 11 small areas by secondary subarea grade system,and its corresponding comprehensive control measurements were put forward. |
