摘　　要：黄淮海平原处于半湿润地带,自然条件较为优越,且地域广阔,总面积约35万平方公里,其中风沙化土地的面积204.4万公顷,占总土地面积的5.9％。在风沙化土地中,沙丘占38％,风蚀沙地占42％,沙埋耕地占20％。扩大耕地面积,改造低产田增加粮食产量,是当前国民经济发展的迫切需要。为此,1986年兰州沙漠所进行风沙化土地的形成、特征及开发利用途径的研究,并在山东禹城沙河地区从事开发性应用试验研究工作。风沙化土地经采取“水利先行,林草紧跟,草田轮作,综合利用”的整治措施,取得了较好的经济、社会、生态效益,并得到一定程度上的推广应用。Huang-Hui-Hai plain, situated at subhumid zone, covers an area of 350000km2., 2.04 million ha of which is blownsand land, accounting for 5.9% of total area. Amoung these blownsands sand dune occupies 38%,roded sandy land 42%,sand buried land 20%. In order to enlarge cultivated land area and ameliorate lowyield farmland to meet the increasing food requirement, the ]nstitute of Desert Research, Academia Sinica conducted researches on the formation cause, features and utilization ways of blownsand lands. In the meanwhile various field experiments were carried out in yucheng area. It has proved that first priority was given to water conservancy in combination with afforestation, grass-crop roty-tion and comprehensive uses could achieve better economic, social and ecological benefits.
