| 摘 要： | 以湖南省怀化市会同县为研究区,利用该区1989年、2000年遥感卫星图像和森林资源调查资料,借助3S技术,对研究区11年间农林复合生态系统景观格局的变化进行了研究。从景观面积动态变化、景观要素斑块特征、景观异质性和景观要素空间相互关系4个方面进行了分析,结果表明研究区森林景观不论从面积还是斑块规模上,都是不断增加,景观总体异质性增加,森林景观的优势度升高。

| Abstract: | Based on the TM images and the forest resource researching data of 1989 and 2000,the agri-forest complex landscape pattern changes in Huitong during the eleven years which used by the 3S technigue were studied in the paper.The four factors: the landscape area dynamic changes,the patch feathers,the spatial heterogneity,the relation of spatial and temporal heterogeneity were analyzed in the paper.The results showed that it was increasing in the areas and blocks of the forest landscape of research area.The difference and advance level of overall landscape also increasing. |
