【摘要】 基于TM影像解释和实地考察,查清了德江县石漠化面积为70 693 hm2、占全县土地总面积的34.1%,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16.6%),明确了德江县石漠化的空间分布格局;分析了德江石漠化的危害;从地形地貌、岩性、降水、耕种方式等方面探讨了石漠化的成因,最后提出了德江县石漠化综合防治对策。更多还原

【Abstract】 Based on TM image and field investigation the authors,analyzed the current distributed area(accounts to 70 693 hm~2,34.1% of the total area of Dejiang county) and patterns of rocky desertification,divided developing degrees of rocky desertification(the area of middle degree rocky desertification is more than 16% of the total area of Dejiang county),and studied its influencing effects on regional social and economic development such as cultivated area trends to decrease and contradiction between man and environment is sharp,surface potable water for man and domestic animals tends to reduce,and the drought and flood become more and more frequent.etc.,and explored the causes of rocky desertification of Dejiang county in WuJiang basin.Finally corresponding proposals to harness rocky desertification were suggested.更多还原
