摘要

极端干旱区生态过程与生态现象具有特殊性，分析生态信息的表达模式与方法，对于进一步认识与理解其内涵、特征及规律具有重要的理论价值与现实意义。以20世纪90年代初、2000年的TM和2005年的CBERS-2/CCD影像作为提取生态景观信息图谱的基础资料;依据干旱区MODS特有的耦合关系，将我国极端干旱区的新疆吐鲁番划分为4个一级类型与13个二级类型。同时，借助GIS符号库，从客观真实性与美观实用性等角度，设计了景观生态专题制图符号体系;极端干旱区景观生态信息图谱模式由图形和特殊符号，描述性数字参数，数学模型3个成分组成;在ERDAS8.5及ArcGIS9.0的支持下，编制了景观生态专题图，最终实现了景观要素的图谱表达。

Abstract

Ecological processes and ecological phenomena have their particularities in extreme arid zone. By analyzing the mode and method of expression of ecological information

its meanings andfeatures，as well as its relationships can be easily understood. By using remote sensing images including LANDSAT/ TM in the beginning of 1990s and 2000

as well as CB ERS-2/ CCD in 2005

the 4 first level types and 13 second level types of landscape type in Turpan，an extreme arid zone of China，are classified based on coupling relations in Mountainous Oasis Desert System(MODS).Meanwhile

the thematic symbol system of ecological landscape is designed by using the GIS symbol base and considering the objectivity andpracticability. The ecological information TUPU is constituted of graph and special symbols

descriptive digital parameters，and mathematic models. Under the support of ERDAS 8.5 and ArcGIS 9.0

a landscape ecology map is made.
