中文摘要：

黄河三角洲是我国重要的后备土地资源开发利用区,是土地利用、覆被变化研究的热点区域。本文选择黄河三角洲核心区域垦利县为研究区,采用2001、2005、2011和2014年的卫星遥感数据,基于RS和GIS技术,在ENVI软件支持下,利用监督分类方法,提取了研究区各时相土地利用类型面积及分布信息,研究了该区土地利用时空变化特征与规律,并结合研究时段内的自然和社会经济因素,对研究区土地利用变化驱动力进行了分析。研究结果表明：耕地、盐荒地和滩涂是该区土地利用的主要类型;研究时段内,垦利县土地利用发生了显著变化,陆地面积总体增加,耕地、林草地呈现减少趋势。耕地是减少速度最快、减少面积最大的土地利用类型,建设用地、盐荒地、滩涂则处于持续增长状态。气候水文因素是主要的自然驱动力,而人类的开发建设活动是主要人为驱动力。研究结果对于该区的土地资源合理利用及经济社会可持续发展具有积极意义。

英文摘要：

Yellow River Delta region is an important commodity grain base,with socio-economic development and ecosystem protection contradiction.With the support of ENVI software,based on RS and GIS technology,using remote sensing data in 2001,2005,2011 and 2014,the paper studied the space-time characteristics of land use change by the method of supervised classification,and combining the research period of natural factors and social economic factors,analyze the driving force of land use dynamic change in the Kenli Country.The research indicated that obvious changes of Land Use had taken place in the study area,as the Yellow River silt siltation,land area showed a trend of growth,cultivated land,salt wasteland and shoal land are the main types of land use,cultivated land and forest-grass land are decreasing and the first mentioned of two is the fastest and largest,construction land is continuing to grow.The climatic and hydrological factors were the dominant natural driving forces for land use changes,and exploitative activities of local people were the main artificial driving forces.Kenli County Land Use Change in guiding the sustainable development of the area is important.
