摘要: 沼泽是自然资源,是一个湿地生态系统。编制沼泽图对正确认识沼泽分布规律,深入研究沼泽的发生、发展机制、生态结构以及开发利用等问题,可提洪基础性科学资料。东北地区沼泽面积达5000多万亩,约占全区总面积的3%,占全国沼泽面积的33%,是我国沼泽类型多、分布面积大的地区之一。经过几年来的考察研究,对东北地区沼泽的分布、面积、以及类型积累了一定的资料,为编制东北区沼泽图提供了有利条件。沼泽要素作为专题图内容进行编制,在我国还是第一次。现提出我们在编制1:100万东北区沼泽图(以下简称本沼泽图)中的一些看法,望批评指正。

Abstract: The Northeast Region is one of main swampy distribution area in China. In order to summarize achivement in scientific investigation of swamp, especially elaborate acreage and type of swamp and its distribution regularity as to find a way for Comprehensive development and utilization of swamp resources, the author has compiled and drawn the regional swamp map. The compilation of the swamp map should embody the principle of swampology (the author has suggested that the classification method of Comperhensive factor can be adopted), directly reflect distribution of swamp and its type characteristics, show regional features of swamp distribution and ecological condition, and mirror research level in depth and extent. In expression form, the author used the method combining colour with symbol. It is that the base colour is used to express respective range of swamp type and the added symbol is used to distinguish whether peat exists in swamp or not. The no-proportion symbol is used to express the swamp with acreage less than provided target. In all over compilation and drawing, the author has adopted combinatiye analysis method in informations and field inverstigation with landsat interpretation.
