| 摘 要： | 选取黄河小浪底水库库周1993年和2000年TM遥感影像进行土地覆被变化分析,绘制出蓄水前后的土地利用现状图,计算出土地覆被变化的转移矩阵和景观结构的控制指标,分别从土地利用类型、空间景观结构特征及土地变化过程等方面进行了研究.研究结果表明:小浪底水库的施工和蓄水对库周的土地利用变化和空间景观结构的改变没有太大影响;由于林地向耕地和其它土地覆被类型转变,使得1993～2000年的模地类型由有林地向耕地转化

| Abstract: | The authors used 1993 and 2000 TM images for surrounding districts of Xiaolangdi Reservoir to analyze land cover change.After making the landuse change map from before to after of constructing reservoir,control indices of transfer matrix and landscape structure of land cover change were computed.Some researches were done on landuse categories,characteristics of spatial landscape structure and process of landuse change.The results show that construct and sluice of Xiaolangdi Reservoir do not have big effect on landuse change of surrounding districts and change of spatial landscape structure,and that from 1993 to 2000 the matrix type transformed from woodland to crop field. |

| Keywords: | surrounding districts of Xiaolangdi Reservoir land cover transfer matrix landscape structure |
