| 摘 要： | 黄河中游多沙粗沙区是黄河中下游淤积泥沙的主要来源区,所以研究多沙粗沙区的土地利用与覆盖变化具有重要的现实意义。利用具有时间序列的多沙粗沙区土地利用图,在地理信息系统的支持下,分析了该区1980年到1997年间土地利用的时空变化规律,以及土地利用、土地覆盖变化的驱动因子,并结合多沙粗沙区的自然特征,对该区的水土保持、生态环境建设提出了一些建议。

| Abstract: | The coarse sand area located in the middle reaches of the Yellow river is the main source area which produces the most amount of the deposited sediment in the riverbed of the Yellow river. Consequently, it is very important and practical to study LUCC in the coarse sand area. The land-use temporal and spatial characteristics and driving forces for cover change are analyzed supported by GIS platform with a time series of land-use maps as raw materials. Based on the research results and the region's natural characteristics, some advices on soil and water conservatiom and vegetation restoration are given. |
