摘要

土地荒漠化是困扰人类发展的主要问题一

荒漠生态系统是荒漠化地区可持续发展的基础。以资源环境数据库中的植被空间分布信息为本底

结合最新的调查和遥感资料

利用地理信息、遥感技术和统计手段

对中国荒漠生态系统的空间分布格局进行了详细的分析。中国的荒漠生态系统可以分为5个基本类型

15类生态系统

在海拔、经向和纬向的分布上都存在一定的规律性。在研究各类荒漠生态系统空间分布特征的基础上

分析了荒漠化生态系统的总体特征。

Abstract

Desertification is a serious environmental problem

particularly because desert ecosystem support sustainable development in desertified regions. Based on spatial information of vegetation in an environmental database and on associated remote sensing data and survey information

the authors analyze the spatial pattern of desert ecosystems in western China. Desert ecosystems are classified into five groups and fifteen sub-types. Their spatial distribution is related to elevation

latitude and longitude. Their spatial characteristics are then presented

along with some recommendations for combating desertification.
