贵州黔西喀斯特地区土地利用景观格局分析

Analysis on Landscape Pattern of Land Use in Qianxi Karst Area of Guizhou

为揭示贵州省黔西县实施生态治理措施后的环境状况和生态成果,对其进行土地利用景观分类,并用景观指数定量化来揭示土地利用景观格局分布特征。结果表明:黔西县2010年土地利用景观格局以林地和旱地面积占主导地位,草地和水田面积占支配地位,未利用地面积最小,景观类型较多,几何形状较复杂,并且分布不均匀,边界割裂的程度高,破碎化程度大,完整性和连通性较差。

In order to discover the ecology rewards and the environmental condition under the ecological treatment engineering in Qianxi County of Guizhou Province, the authors classified the landscape types and land use pattern, and quantified the landscape index to reveal the landscape of land use feature. Results： In 2010, the {orest land and non-irrigated land were the dominated land use patterns in the study area. The grass land and irrigated land were the dominant land use patterns. However, the area of underdeveloped land was the smallest among all patterns; The landscape types in Qianxi County was vary and geometrical complicated, there was a high degree in boundary isolation, the landscape fragmentation and the landscape connectivity were both in a low level.
