摘 要:利用3S技术,分析了黄淮海平原风沙化土地典型区内的内黄、滑县和延津三县1979—2009年夏季土地利用变化特征。结果表明:该区近30 a的土地利用类型变化显著,变化趋势为耕地、水域和未利用地面积持续减少;林地和建设用地面积不断增加。黄淮海平原以风沙化土地为主的未利用地的利用,对研究区各土地类型之间的平衡起至关重要的作用。研究区土地利用演变规律性较强,社会经济的发展对该区林地、建设用地和耕地变化影响明显。The summer land use quantity change character of the typical region of wind-sandy land in the counties of Neihuang,Huaxian and Yanjin of the Huang-Huai-Hai plain between 1979 and 2009 was analyzed by means of 3S technique.The results show that the land use type has been changed evidently in the region in the recent 30 years,the trend of land use change is as follows: the areas of cultivated land,waters and unused land decrease continually,while the areas of forest land and construction land show an increase trend.The use of unused land in the Huang-Huai-Hai plain,where is main wind-sandy land,plays important role in balancing diversified land types in the studied region.In the studied region,the evolvement regularity of land use is relative better,and the social and economic development evidently effects the area change of forest land,construction land and cultivated land.
