干旱区生态景观制图的谱型特性与模式方法

Characteristics and Methodology of Ecological Landscape Mapping in Arid Zone

生态景观制图是专题制图学的重要发展方向之一。其主要特点表现在可以揭示自然要素和人为作用的特点 ,反映各景观要素的相关性和数量关系。本文选择以新疆和田为代表的干旱区生态景观制图 ,通过遥感与 GIS相结合的方法 ,对生态景观制图的信息识别、信息挖掘、综合分析应用等研究 ,探讨了地图信息认知、表达、反演等专题制图中的生态景观分类、动态变化问题。

Ecological landscape mapping is one of the fields of thematic mapping.There are some characteristics, such as, the mapping can reveal the features of natural elements and artificial functions and reflect correlative and quantitative relations of all kinds of landscape elements.Furthermore,it has advantages of combining principles with practice.Based on the methodology and principles of remote sensing and GIS, the ecological landscape maps of Hotan,a representative of the arid zone, are made.Meanwhile, some principles and methodology of geographical information science are emphasized for thematic mapping.Especially, the effects of ecological mapping on information identification, information mining, and information integration and information analysis are showed.Moreover, the importance of classification and dynamic changes and analysis of ecological landscapes are pointed out for information cognition and expression and retrieval.
