| 摘 要： | 应用遥感和GIS技术，采用多样性指数、破碎度指数和分维数等指数，分析了广州市花都区1979年到2000年的景观动态变化，结果表明：（1）各景观类型的斑块数量增加，面积变化较大，且斑块形状复杂性增加；（2）景观破碎度增大，景观类型稳定性增加，优势度减少，受人类干扰程度加深；（3）景观斑块间的转移中，林地、耕地不断转移为城市用地、农村居民点以及工矿等用地，农村居民点以及工矿等用地也成为景观格局中的主要组成要素；（4）整体上景观变化后10年比前10年的幅度稍大。

| Abstract: | With the help of GIS,and based on RS image MSS of 1979,TM of 1990 and ETM of 2000,and by using the indices of the landscape pattern,this paper studied the landscape change from 1979 to 2000 in Huadu Section of Guangzhou city. The results show that: (1) In Huadu Section,there were rapid increases in the patch number and area variety. (2) The residential area and construction area in this section increased. (3) The woodland and farmland were mainly transformed to construction area and residential area. (4) The landscape change was accelerating in the study area. |
