万州区位于长江中上游三峡库区腹心,承载着三峡库区生态环境保护和移民安稳致富的双重使命。本文依据万州区土地变更调查资料,在GIS技术的支持下,结合万州区自身的区位和地貌特征,对万州区2009-2013年间土地利用变化特征进行追踪与研究。结果表明:研究区土地利用结构相对稳定,土地利用综合程度处于中等水平,耕地、林地为区域主要的土地利用类型;单一土地利用动态度变化各有不同,其中建设用地面积增长较为明显,林地和耕地的面积有所减少。本文旨为万州区土地资源的合理开发利用提供理论依据和数据支持。
Located in the heart of the Three Gorges Reservoir in the middle and upper reaches of the Yangtze River, Wanzhou District carries the dual mission of ecological environment protection and immigration stability in the Three Gorges Reservoir Area. Based on the survey data of land change in Wanzhou District and with the support of GIS technology, this paper traces and studies the land use change characteristics of Wanzhou District from 2009 to 2013 based on its own location and landscape features. The results showed that the land use structure in the study area was relatively stable, the comprehensive degree of land use was at a middle level, and the cultivated land and forest land were the main types of land use. The dynamic change of single land use varied, including the obvious increase of construction land area, The area of cultivated land has been reduced. This paper aims to provide a theoretical basis and data support for the rational development and utilization of land resources in Wanzhou District.
