| 摘 要： | 基于GIS／RS环境对两期TM影像数据进行土地利用分类处理,运用土地利用转移矩阵、景观格局分析软件Fragstats3．3,对河北省沽源县土地利用及景观格局变化进行了动态研究。结果表明：随着京津风沙源治理工程的实施,沽源县土地利用景观格局发生了很大变化,土地利用类型变化最明显的是林地、未利用地和耕地,并以林地的增加为主,土地利用景观异质性在增强,景观多样性有所减少和景观组分趋向均匀分布,景观聚集度适中且小斑块数量增多,空间连接性减少,空间分布趋向均衡化分布,斑块形状总体上仍然有规律、简单,受人类干扰程度有所减少。

| Abstract: | Using the techniques of RS,GIS and landscape ecology,based on Landsat TM data of 2002 and 2007,integrating with land use transform matrix and landscape pattern analysis software Fragstats 3.3,the dynamic changes of land use and landscape pattern from 2002 to 2007 in Guyuan County were studied.The main results show that the structure of the land use has been greatly changed with implementing Sandstorm Source Control Project in and Around Beijing and Tianjin.Firstly,the most quickly changed land types are for... |
