摘    要:借助于GIS技术,从景观生态学的角度出发,以沿海的电白县为例,按照土地利用类型进行景观格局划分,并通过其指数的变化对局地土地利用动态变化进行研究。结果表明:2005—2009年电白县沿海滩涂沼泽面积明显增加,水域大幅度减少,其余也有一定量的增减。土地利用斑块数目增加,分维数和分离度呈增加趋势,多样性和均匀度均呈下降趋势,景观格局的空间异质性下降,优势度有所增大,破碎度增加,人类活动对景观格局的干扰程度较大。

关 键 词:土地利用  景观格局  动态变化

Abstract:Based on GIS technology,from the perspective of landscape ecology and by taking Dianbai County for example,the paper had made landscape layout division according to land use types and studied dynamic change of local land use through indexes' change.The result showed that coastal everglade in Diantai County had increased obviously while water area had decreased substantially and other lands also decreased in a way from 2005 to 2009.The number of land use patches increased,fractal dimension and splitting degr...
Keywords:Land use  Landscape pattern  Dynamic change
