摘要

[目的]研究科尔沁沙地土地利用时空演变特征，为该区土地资源的合理开发和生态环境的改善提供科学依据。[方法]基于土地利用重心迁移模型，利用1980-2016年Landsat系列卫星影像，分析该地区土地利用时空格局和空间转移特征。[结果]1980-2016年科尔沁沙地植被重心向西北方向迁移，迁移速率为64.6 m/a；水体向东南方向迁移，迁移速率为389.3 m/a；建筑用地向东北方向迁移，迁移速率为53.6 m/a；沙地向西南方向迁移，重心迁移速率为379.5 m/a；耕地向东北方向迁移，重心迁移速率为148.3 m/a。[结论]1980-2016年科尔沁沙地各土地利用类型在不同时期的重心迁移速率有较大差异，建筑用地总体迁移速率最小，水体和沙地的重心迁移速率相对较大，该现象主要与科尔沁沙地生态环境脆弱有关，造成了水资源持续性减少以及沙地随时反弹。

Abstract

[Objective] The spatial and temporal evolution characteristics of land use in Horqin sandy land were studied in order to provide basic information for appropriate decision-making.[Methods] Based on the gravity center migration model of land use

the patterns and characteristics of spatial-temporal dynamics induced land use were analyzed with Landsat images from 1980 to 2016.[Results] The gravity center of vegetation migrated to the northwest at a rate of 64.6 m/a

and water body migrated to the southeast at a rate of 389.3 m/a. The gravity centers of construction land and cultivated land both migrated to the northeast at rates of 53.6 and 148.3 m/a

respectively. The gravity center of sandy land migrated to the southwest at a rate of 379.5 m/a.[Conclusion] There were great differences in the migration rate of gravity center among different land use types in different periods. The overall migration rate of construction land was the smallest

and water body and sand land were relatively large. This phenomenon was mainly related to the fragile ecological environment of Horqin sandy land

resulting in the sustained reduction of water resources and the rebound of sandy land at any time.
