利用3S技术处理遥感图像,分析了湘西自治州石漠化的现状和分布。结果表明,湘西州各县市石漠化面积比重表现为:凤凰县(53.41%)>花垣县(45.35%)>吉首市(44.91%)>永顺县(39.52%)>保靖县(39.45%)>龙山县(29.89%)>泸溪县(25.96%)>古丈县(24.57%);并针对存在的问题,提出了采用生物措施和工程措施相结合的水土保持措施,因地制宜,逐步改善湘西州石漠化现状。
The remote sensing images of Xiangxi prefecture were processed by 3S technology, and the distribu- tion of rocky desertifieation in Xiangxi autonomous prefecture was analyzed. The results showed that : proportion of rocky desertification area in Xiangxi showed as: Fenghuang county(53.41% ) 〉 Huayuan county(45.35% ) 〉 Jishou city ( 44. 91% ) 〉 Yongshun county ( 39. 52% ) 〉 Baojing county ( 39. 45% ) 〉 Longshan county (29. 89% ) 〉 Luxi county(25.96% ) 〉 Guzhang county(24.57% ).
