中文摘要	针对我国西部干旱半干旱区典型流域的土地利用与景观格局时空变化特征分析问题,以近35年来的5期Landsat卫星遥感影像为数据源,利用变化监测技术和景观生态学分析算法,对石羊河流域的土地利用和景观格局时空变化特征进行分析,结果表明:1)近35年来,由于人类的活动,石羊河流域居民地和耕地大幅增加,水体、草地、林地面积大幅减少,生态环境日益恶化。2)研究区不同地类之间出现不同程度的转移现象,主要是较大面积的未利用土地和草地转化成了耕地,部分草地转化成未利用土地。3)景观格局在各个研究时段也发生了明显的变化,整个景观的密度是先增后减,说明流域的开发已有所节制。
英文摘要	For analyzing the spatial and temporal variation of land use and landscape pattern in typical semi-arid and arid watershed of western China, we used change monitoring techniques and the landscape ecology analysis algorithms to discuss the temporal and spatial variation of land use and landscape characteristics of Shiyang River Basin, based on five Landsat satellite remote sensing images in recent 35 years. The results showed that:1)As a result of human activity, residential areas and farmland increased rapidly. Water, grassland, and woodland areas reduced significantly with the deterioration of ecological environment. So the ecological environment of the Shiyang River Basin deteriorated significantly in the last 35 years. 2)There were varying degrees of transfer between different land use types in the study area. A lot of unused land and grassland was reclaimed into farmland, and part of grassland degraded to unused land. 3)Landscape in each study period also occurred significantly change. The entire landscape of the density was decreased at first and then increased. Those indicated that the development of the basin had been restrained effectively.
