摘　　要：土地利用的动态监测及其影响因子的分析,有助于了解地区发展的一般特征及趋势,提高城市用地规划的科学性与合理性。本文以黄河三角洲为研究区,基于RS技术,利用3期Landsat遥感影像(2009、2015和2019年),采用监督分类方法提取了黄河三角洲地区的土地利用类型,依据提取结果对10年间土地利用类型进行了动态变化监测与分析。结果表明,2009—2019年期间,盐田、建筑用地和耕地的面积持续增加,分别增加了952.56、605.99和302.54 km^(2);盐碱地、植被、滩涂与水产池塘等地类面积持续减少,分别减少了1033.56、377.53、110.77和336.14 km^(2);其他地类面积或有增减,变化不大。The dynamic monitoring of land use and the analysis of its influencing factors are conduced to understand the general characteristics and trends of regional development,and to improve the scientific city and rationality of urban land use planning.This paper takes the Yellow River Delta as the research area,based on RS technology,using three phase Landsat remote sensing images(2009,2015 and 2019),extracts he land use types in the Yellow River Delta region with supervised classification method,and analysis the dynamic monitoring of land use types in 10 years according to the extraction results.The results show that during 2009-2019,the area of salt field,construction land and cultivated land respectively increase by 952.56,605.99 and 302.54 km^(2);the area of saline alkali land,vegetation,beach and aquatic pond decrease continuously,respectively decrease by 1033.56,377.53,110.77 and 336.14 km^(2);the other land types may increase or decrease,and the change is not obvious.
