哈尔滨市土地利用变化及驱动力分析

Analysis of Land Use Change and Driving Forces in Harbin City

摘要: 本文利用ArcGIS 10.4解译哈尔滨市2000年、2010年和2020年遥感影像，利用土地利用转移矩阵和土地利用变化模型定量分析哈尔滨市2000年以来土地利用类型和土地利用观的时空动态变化，运用多种方法分析哈尔滨市土地利用类型演变特征、空间演化特征及其影响因素，旨在为哈尔滨市土地利用优化发展提供科学依据。结果表明：1) 哈尔滨市不透水面和未利用地面积增加，水体先减后增，耕地、林地和草地总体呈减少趋势。2) 在空间变化上，土地利用变化区域建设用地、耕地、林地重心迁移呈现先缓后快的阶段性特征。3) 哈尔滨市土地利用变化驱动因素主要是政策、经济、人口、交通因素。

Abstract: This paper uses ArcGIS 10.4 to interpret the remote sensing images of Harbin in 2000, 2010 and 2020, quantitatively analyzes the temporal and spatial dynamic changes of land use types and land use views in Harbin city since 2000 by using the land use transfer matrix and land use change model, and analyzes the evolution characteristics, spatial evolution characteristics and influencing factors of land use types in Harbin city by using various methods, aiming to provide a scientific basis for the optimal development of land use in Harbin city. The results showed that: 1) The area of impervious surface and unused land in Harbin increased, the water body decreased first and then increased, and the arable land, forest land and grassland showed an overall decreasing trend. 2) In terms of spatial change, the migration of the center of gravity of construction land, cultivated land and forest land in the area of land use change shows the phased characteristics of slow first and then fast. 3) The driving factors of land use change in Harbin are mainly policy, economic, population and transportation factors.
