摘    要:以陕西省神木县窟野河流域的六道沟为例,探讨利用景观格局数量指标计算法,并运用马尔可夫链转移矩阵研究不同时段土地利用/覆被的时空变化。其步骤如下:首先,数字化三期利用图,并在ARC/INFO下统一坐标系统;其次,遴选景观格局数量化指标;然后,在统计软件下计算各指标值;最后进行研究区域土地利用/覆被时间-空间变化的分析和讨论,得出土地利用/覆被经年经年变化趋势。其结果可为黄土高原水蚀风蚀区的土地资源合理利用、土地利用规划和控制水土流失等提供科学依据。

关 键 词:黄土高原  水蚀风蚀交错区  土地利用/覆被  时空变化

Abstract:Taking the Liudaogou watershed which is located in Shenmu County, Shaanxi Province as the exam- ple, based on the landscape quantitative calculating method and the Markov transforming matrix, the spatio-tem- poral change of landuse/cover at the different period was discussed. The steps were following: first of all, to digi- tize the three landuse maps and unified the coordinate of these maps; secondly, to chose the suitable landscape quantitative indicators and next, calculated them under the statistic software, at last, to analyze the trend of spa- tio-temporal change from different landuse/covers. The results would provide the scientific support for rational us- es of soil resources, land use plan and soil and water controlling in Loess wind-water erosion crisscross region.
Keywords:Loess Plateau  wind-water erosion crisscross region  landuse/cover  spatial-temporal change
