威宁县石漠化监测结果分析与治理对策

Analysis of Monitoring Results and Control Measures for Stony Desertification in Weining County

为分析威宁县石漠化监测结果,总结治理对策。采用“3S”集成技术,以威宁县第四次石漠化调查监测结果为依据,开展了威宁县第四次石漠化调查,通过调查和系列数据处理分析。结果表明:全县潜在石漠化面积62042.30 hm^(2),石漠化面积44664.45 hm^(2),其中轻度石漠化面积27035.04 hm^(2)、中度石漠化面积15876.73 hm^(2)、重度石漠化面积1652.87 hm^(2)、极重度石漠化面积99.81 hm^(2)。威宁县岩溶地区的中度石漠化土地有所改善,但石漠化分布极不均匀,仍需不断加强石漠化综合治理。

By analyzing the monitoring results of stony desertification in Weining County,the control measures were summarized.Methods:The"3S"integrated technology was used to carry out the fourth stony desertification survey in Weining County based on the results of the survey and data processing.The potential stony desertification area of the county was 62042.30hm^(2) and 44664.45hm^(2),including 27035.04hm^(2) of mild stony desertification,15876.73hm^(2) of moderate stony desertification,1652.8787hm^(2) of severe stony desertification and 99.81hm^(2) of extremely severe stony desertification.Conclusion:The moderate stony desertification land in the karst area of Weining County has been improved,but the distribution of stony desertification is very uneven,so it is necessary to strengthen the comprehensive control of stony desertification.
