摘要
[目的]深入探索土地"三生"(生态、生活、生产)功能格局特征,为土地利用总体规划提供指标控制的科学依据。[方法]利用内蒙古和林格尔县1996,2006,2015年3期遥感数据,采用动态度、空间变化分析模型、空间变化率指数对研究区"三生"用地数量变化、空间变化及其变化集聚特征进行分析。[结果](1)研究期间生态用地减少数量突出,后期逐渐减缓;生产生活用地增加幅度明显,年均变化率达5.9%,动态度达12.06%;从整个空间变化率分析,生产生态用地两期变化均强烈,生产生活用地呈增强趋势,生态用地变化逐渐减弱。(2)研究区"三生"用地空间变化前期集聚在黄土丘陵区和山区,后期集聚在平原地貌类型区。[结论]经过20a规划管控,研究区"三生"用地逐步形成北部平原区以生产生态用地和生产生活用地为主的生产生活空间,中部、南部黄土丘陵区和山区以生态用地和生态生产用地为主的生态空间,且生产生活用地功能区扩张和生产生态功能区减少的矛盾得到一定程度遏制。
[Objective] To investigate the variation of land ecological-living-industrial function pattern in order to provide scientific basis for the overall plan for land utilization.[Methods] With the interpreted maps from TM imagery in 1996, 2006 and 2015 of Helingeer County, Inner Mongolia, the quantity, spatial changes and the agglomeration characteristics of ecological-living-industrial land was analyzed by using the spatial analysis model and spatial change rate model.[Results] ① The amount of the ecological land decreased greatly at the initial stage, and then slowed down. The increase of industrial-living land was obvious, the annual rate of change was 5.9% and the dynamic degree was 12.06%. The spatial variation of industrial-ecological land varied dramatically. Industrial-living land showed a great increasing trend, and the variation of ecological land weakened gradually. ② The spatial variation of living-industrial land distributed in loess hilly region and mountainous region at earlier stage, and in the plain region at the later stage.[Conclusions] After 20 years of planning control, the industrial-ecological land and industrial-living land was mainly distributed in the north plain area, while the ecological land and ecological-industrial land was mainly distributed in the central and southern part in loess hilly and mountainous region. Moreover, the contradiction between industrial-living land expanding and the industrial-ecological land reducing has been contained at a certain extent.
