摘要
以新疆艾比湖流域平原区为对象,在对研究区进行景观生态分类及野外调查验证的基础上,利用"3S"技术将1∶100×104的新疆土壤类型图与研究区景观类型图叠加,从土壤属性层次上对研究区各类景观的生态土壤类型进行确认,并分析其在研究区内分布的特征。结果表明:研究区主要土壤类型为26类,以石膏灰棕漠土所占比例最大,占研究区总面积的19.03%,棕钙土、荒漠风沙土、草甸盐土、盐化草甸土、和灌耕灰漠土等面积也较大。
Taking the plain region of Ebinur lake basin as an example,landscape classification map of the research area and 1∶100×104 soil type map of Xinjiang are overlapped by using ＂3S＂ technology based on type division of landscape ecology and field investigation to this area.Than,ecological soil types of different landscapes in research area are identified depending on the different levels of soil attribute,and distributing characteristics of them in the plain region of Ebinur lake basin are analyzed.The outcomes show that there are 26 dominating types of soil in research region,in which the area ratio of gypsum gray-brown desert soil to the total research area is the maximal,the value is 19.03%,and the ratios of brown-calcium soil,desert sand soil,meadow solonchak,salined meadow soil,cultivated gray desert soil are higher in turn.
