以独山县2013年林地年度变更小班为基础数据，结合实地调查，通过建立指标体系、利用熵值法计算指标权重、利用加权平均法计算石漠化程度得分，对坝望河小流域进行石漠化评价研究。结果表明：研究区有372.71hm2的石漠化土地，其中中度石漠化、重度石漠化和极重度石漠化分别占石漠化土地的37.68％，19.79％和42.53％。在此基础上分析了研究区的石漠化成因，并有针对性地提出了一些对策建议，以期为岩溶地区的石漠化治理提供一定的参考依据。
以獨山縣2013年林地年度變更小班為基礎數據，結閤實地調查，通過建立指標體繫、利用熵值法計算指標權重、利用加權平均法計算石漠化程度得分，對壩望河小流域進行石漠化評價研究。結果錶明：研究區有372.71hm2的石漠化土地，其中中度石漠化、重度石漠化和極重度石漠化分彆佔石漠化土地的37.68％，19.79％和42.53％。在此基礎上分析瞭研究區的石漠化成因，併有針對性地提齣瞭一些對策建議，以期為巖溶地區的石漠化治理提供一定的參攷依據。

Based on the data of the annual forestland changes of the subcompartments in 2013 in Dushan County and combined with the field survey,rocky desertification in the small watershed of the Bawang River was evaluated through establishment of the index system and use of entropy method for calculating the index weight and use of the weighted average method for calculating rocky desertification degree.The results showed that there was 372.71 hectares of land suffering rocky desertification in the study area.The percentages of moderate desertification,severe and very severe rocky desertification were 37.68%, 19.79% and 42.53%respectively.On the basis of the analysis results,the desertification formation in the study area was studied and some suggestions was put forward in order to provide some reference for rocky desertification control of karst region.
