土地覆盖(即地表下垫面)是土地生态环境的基本组成部分。因此,一个地区的土地覆盖状况如何,乃是开发利用该地区国土资源工作中最引人关注的问题之一。为了三峡工程建设和该地区其它发展的需要,对这一地区的生态环境加深研究,摸清它的基本情况,包括地表覆盖情况,颇为重要。本文拟就这个地区土地覆盖的结构、质量及其环境影响提出一个初步的分析。
Land cover (ie, surface underlying surface) is an essential part of the ecological environment of the land. Therefore, how the land cover of a region is covered is one of the most interesting issues in the development and utilization of land and resources in the region. In order to deepen the study of the ecological environment in this region and find out its basic conditions, including the coverage of the land surface, for the construction of the Three Gorges Project and other needs in the region, it is of great importance. This paper proposes a preliminary analysis of the structure, quality and environmental impact of land cover in this area.
