| 摘 要： | 以新疆塔克拉玛干沙漠南缘中部的策勒绿洲为例，利用SOPT4卫星遥感数据，借助ERDAS image和Arc/View软件，对其荒漠－绿洲景观类型进行分类并形成研究区栅格景观分类图，一共分为14类景观类型。在栅格分类图的基础上生成矢量化的分类图，进而使用ARC／INFO与FRAGSTATS景观格局分析软件计算9种类型的景观参数，并从斑块、类型和景观3个水平上详细列出近70几种相应的参数和景观指数，定量化地揭示了策勒绿洲的景观分布格局与类型特征。

| Abstract: | Qira oasis is located in the middle of the TaNan region and represents a typical desert oasis ecosystem of the southern Xingjiang Province in northwest China. Several oases occur in this region that are totally dependent on rivers that originate from the Kunlun Mountains. The study area was selected as a SPOT 4 scene covering Qira oasis and its surroundings. This study pursues two goals: (1) to produce a landscape classification map, and (2) to evaluate the applicability of landscape pattern indices to a q... |
