摘要
针对边境城市土地利用变化频繁,人地矛盾突出的问题,该文以黑龙江省绥芬河市为研究区,GIS技术为基础,基于2009—2016年Landsat卫星遥感影像进行人机交互目视解译,综合利用土地转移矩阵、标准差椭圆分析、热点分析和密度分析对研究区进行土地利用时空变化特征研究。结果表明:2009—2016年,研究区耕地面积减少最多,建设用地面积增长明显;土地利用空间变化以东北—西南方向为主轴发生倾斜,集中分布在西南部和中部地区;土地利用变化热点与点密度核心区为西南部小绥芬河流域和寒葱河沿岸地区、中部绥芬河市交通枢纽以及东部绥芬河市中俄通商口岸地区,北部的绥芬河林场变化程度极低。研究成果可为边境城市土地利用规划及可持续发展提供科学依据。
Aiming at the problems of frequent land use change and prominent contradiction between human and land in border cities, this paper took Suifenhe city of Heilongjiang province as the research area, GIS tech no logy as the basis,based on the La nd sat satellite remote sensing images from 2009 to 2016, the human computer interactive visual interpretation was carried out,and the land use spatiotemporal variation characteristics were studied by using the land transfer matrix, the standard deviation ellipse analysis. the hot spot analysis and the density analysis. The results showed that. in the 2009一2016 years, the area of cultivated land was reduced most, the area of construction land was increased obviously;the spatial change of land use was inclined to the northeast and southwest direction. concentrated in the southwest region and central region;the core areas of land use change hot spots and point density were the small Suifenhe basin in the southwest and the coastal area of the Han Cong River in the southwest. the hub of Suifenhe in the middle of the central region,and the Sino Russian trade junction in the eastern Suifenhe city,and the change degree of the Suifenhe forest farm in the north was very low. The research results can provide scientific basis for land use planning and sustainable development of border cities.
