    摘要:

    基于中国西南部中小城市曲靖市2006、2011、2015年TM影像图,依托ArcGIS10.2和ENVI5.1,采用最大似然法,结合转移矩阵和各时段单一用地类型对比图,定性定量地研究评价土地利用变化情况及驱动力,从土地利用现状、土地利用转移情况以及土地利用变化驱动力3个方面研究曲靖市土地利用/土地覆被变化(LUCC);研究结果表明:在研究年限内曲靖市土地利用情况总体科学合理,其中耕地、灌草主要受限于气候和政策原因变化较为剧烈,在2006—2011年和2011—2015年时段均接近其总量的50%;建设用地以城市中心向四周扩张,在两个时段向其他用地转移维持在20%左右,主要集中于麒沾马一带人口密集区;研究可对曲靖市该时段的发展情况评价提供依据,对曲靖市土地利用和发展规划有一定的指导作用。

    Abstract:

    Based on TM image of Qujing City, a small city in the center of southwest China, in 2006, 2011 and 2015, this paper quantitatively and qualitatively evaluates land use/land cover change(LUCC) of Qujing City from such three aspects as the change of land use and the status quo and the transfer situation of driving force from land use as well as the driving force of land use change by relying on ArcGIS10.2 and ENVI5.1, by using the maximum likelihood method, by combining the transfer matrix with each period of single land use type comparison chart. The research results show that in the studied years, the land use situation of Qujing City overall is rational and scientific, among which the cultivated land, shrub and grass mainly depend on the climate, policy change is more intense, during 20062011 and 2011—2015 period, the land use is close to 50% of the total, the construction land expands to surroundings from city center, the other land use maintains at 20% in the two periods, which is mainly concentrated in the densely populated area along Qilin District and Zhanyi County. This research can provide the basis for evaluating the developing situation of Qujing City in these periods and has certain guidance to land use and development plan of Qujing City.
