摘要: 环境地图是空间环境信息图形转换、储存与传递的新型专题地图。本文阐述了环境地图的性质、任务、基本类型及点、线、面状环境信息转换为图形信息传输的基本方法,并展望了进一步发展的方向。

Abstract: The environmental map is a new kind of special map for transforming, storing and transmitting spatial environmental information figures, on the basis of the research results of environmental sciences and the theory of cartography. It serves a particular function in the study of regional environment. The analytical mapping and integrative mapping of environmental maps are the means of the scientific generalization and comprehensive summation of regional environmental study, and an important expressive form of research results of regional environment as well.Environmental map itself is a special research method of regional environmental regularity.Its mathematic accuracy and geographical basis are the criterion for verifying the accuracy of regional environmental location and judging the level of regional environmental research. Environmental map can be divided into natural environmental backround map, environmental medical map,environmental pollution map, environmental quality prediction map, environmental protection engineering map and so on, according to the contents and characteristics of mapping information. The expression method of environmental map is to transform environmental information into figure information for transmitting. The environmental information distribution has three basic forms of point, line and area. The environmental information distributed in point shape should be transformed into figures of location symbol and location statistics. Line-shape information can be transformed into line-shape figures or figures of location statistics. Areal information can be transformed into eolour base figures, isogram, net figures, point number figures, graded statistical figures, divisional statistical figures and range figures respectively based on concrete features.
