摘要
本文以2005年SPOT5遥感影像和1992年1∶10000海伦市土地利用矢量数据为基础,将RS与GIS技术相结合分析了13年来海伦市土地利用动态变化情况.研究结果表明,13年来海伦市的耕地、草地、建设用地和水域都呈增加趋势,分别增加了12763.5 hm2、1517.2 hm2、883.9 hm2、607.7 hm2;而林地和未利用地分别减少了1678.8 hm2、14093.5hm2.本研究通过对海伦市土地利用更新调查数据分析,为合理利用有限的土地资源和城市的可持续发展提供科学的决策依据.
The article analyzed the land use dynamic change between thirteen years of Hailun city,based on SPOT5 remote sensing in 2005 and land use vector data in the ratio of one to ten thousand of Hailun in 1992 using RS and GIS technologies that is combined with.The results indicated the area of field land,grassland,construction land and water increased 12763.5 hm2,1517.2 hm2,883.9 hm2,607.7 hm2 while the area of forestry and not used land decreased 1678.8 hm2,14093.5 hm2 respectively during 13 years.The studies provided the scientific decision-making for using limited land resource in reason and developing the city continually through analyzing the land use updating investigation of Hailun.
