【摘要】 以1990年和2005年泰山区的1:1万土地利用现状图为数据源,运用ArcGIS软件进行空间叠加分析,提取其中的属性数据,获得近15年来研究区的土地利用变化规律。结果表明:研究区园地和居民点及工矿用地的变化量最大,其中园地减少了53.93%,主要开垦为耕地;居民点及工矿用地增加了44.40%;林业用地增加了18.90%,主要由园地、耕地和未利用地转换而来;耕地总量减少了5.44%;未利用地减少了34.13%。并找出了研究区耕地浪费的原因和农业结构调整混乱、建设用地迅速扩大等问题,提出了严格保护耕地和建设用地的审批等建议,为调整人类自身活动、优化配置资源、改善生态环境、实现土地可持续利用提供依据。更多还原

【Abstract】 With the 1:10000 map of land use status in 1990 and in 2005 of Taishan District as the source of data,this paper uses ArcGIS software to do the overlapping analysis and distill its properties,obtaining the rule of land use change of the research area in the past 15 years.The results show that there had been greatest change in garden land and construction land,with garden land decreasing by 53.93%and mostly converted into farmland,that residential land and industrial land area had increased by 44.40%and forest land by 18.90%,mostly converted from garden land,and that farmland had decreased by 5.44%and unexploited land by 34.13%.The paper discloses the cause for the waste of land and such problems as disordered agricultural structure adjustment and fast increase of construction land and proposes protecting the arable land strictly and controlling the rule of construction land approval and so on,providing bases for the improvement of eco-environment and the sustainable land use.更多还原
