呼伦贝尔市土地利用动态变化研究

土地利用动态研究是全球变化研究的核心 ,是涉及到人类可持续发展的新兴的研究项目。本文以系统论、持续发展论为指导 ,对呼伦贝尔市土地利用时空变化进行了较深入、系统的研究。文中 ,以地理信息系统技术为研究手段 ,利用时间序列动态模型、动态度模型、分布重心模型和主要土地利用类型空间变化图对呼伦贝尔市近十多年的土地利用时空变化趋势、变化速率进行了分析 ,得出耕地正在向西北方向扩展 ,且速度快 ;林地稍有扩展趋势 ;牧草地面积则快速减少 ,向西南方向萎缩的结论 ,并从一定的深度研究了土地利用变化所带来的环境影响

Dynamic Study of Land-use in Hulunbier City

Dynamic study of Land-use is the core of global change studies, and is new study-item in connection with sustainabie development . Based on the theories of systematology and sustainable development,the temperal and spatial chenges of landuse of Hulunbier were probed. Firstly, the tendency of space-time changes of land-use of Hulunbier and change-rate of it in decade were analyzed by GIS, dynamic model of time-list and the model of distributive center of gravity etc.. Secondly, the conclution was drown that the areas of farming land are extending quickly to northwestwards; areas of woodland extende slightly; grassland areas decrease quickly to southwestwards, and the change of land-use resulted to environmental changes.
