| 摘 要： | 将复杂网络研究的理论和方法引入到小清河流域LUCC(土地利用/覆被变化)研究中,以1984-2010年小清河流域土地利用/覆被变化转移矩阵作为网络,通过度、介数和平均路径长度等统计指标,从系统整体的层面分析了地类演变模式,识别土地系统的关键地类,分析其整体的稳定性演变。结果表明,耕地是小清河流域主要的转出型地类,水域湿地和建设用地则是主要的转入型地类;耕地是系统的关键地类,流域的LUCC过程主要围绕耕地展开。流域土地系统的稳定性较弱,且总体上表现出下降趋势。

| Abstract: | Based on the theory and method of the networks,this study explored the conversion models under different land-use types,identified the key land-use type,and analyzed the whole results of the conservation.Statistical indexes such as degree,betweenness and average path length were employed.The LUCC(land use/cover change)during the period from 1984to 2010in Xiaoqing River watershed were taken as a case study.The results indicated that farm land was the main land type that was converted from other land types,while the water land, wetland and construction land were the main land types that could be converted into the farm lands.The farm land was the key land type in the land type networks,by which the watershed LUCC was processed. The stabilization of land system was relative low,and this stabilization showed a decreasing trend. |
