摘　　要：对2002年番禺区的卫星影像进行分析,得到土地利用类型的分类数据,根据自然特点和人文特点将研究区划分为3个梯度区,运用景观生态学的方法定量研究土地利用空间结构的梯度变化。结果表明,番禺区的景观多样性和均匀度下降;人工景观类型逐渐减少,自然、半自然景观类型逐渐增加;斑块的几何形状由简单到复杂。The categorical data on land use types of Panyu district was obtained on the basis of analyzing its satellite image in 2002, and the study area was divided into 3 gradient regions according to its natural and humanities characteristics. The gradient change of land use and spatial structure was quantitatively studied with landscape ecology method. The results showed that the diversity and uniformity of the landscape in Panyu district were decreased. The artificial landscape types were gradually decreased, while the natural and half-natural landscape types were gradually increased. The geometry shape of the patch was changed from simple to complex.
