中文摘要	以黑河中游荒漠-绿洲过渡带斑块植被区的风蚀积沙观测资料为基础,结合中国生态系统研究网络(CERN)临泽内陆河流域研究站的风况资料,应用地统计学方法对20122013年风蚀季(38月)的风蚀积沙过程进行分类,并分析起沙风对风蚀积沙量的影响。结果表明:(1)20122013年风蚀季风蚀积沙量的空间变异过程分为随机性变异过程(2012年47月)和结构性变异过程(2012年8月及2013年37月)。(2)在随机性变异过程中,风蚀积沙量与起沙风的风速、风向、风频率依次相关;在结构性变异过程中,风蚀积沙量与起沙风的风向、风速、风频率依次相关。③输沙势(DP)与风蚀积沙量的相关性大小为随机性变异过程>结构性变异过程;在随机性变异过程中,合成输沙势(RDP)与风蚀积沙量无明显相关关系(R~2=0.0745);而在结构性变异过程中,合成输沙势(RDP)与风蚀积沙量的相关系数较高(R~2=0.9343)。④在随机性变异过程中,各月风蚀积沙量呈不规则的片状分布;在结构性变异过程中,各月积沙量呈明显的带状分布。
英文摘要	With the data of the sand-driving wind collected in the Linze Inland River Basin Research Station which is about 2 kilometers away from the sampling area,we observed the wind erosion sediment directly in the patch vegetation zone of oasis-desert ecotone in Linze,Gansu in 2012-2013.The results showed that:(1)From April to July in 2012,the process of the wind erosion sediment was randomly variatied.While in August of 2012 and from March to July in 2012,the process was with a structural variation.(2)In the process of random variation,the correlation relationship between the sand-driving wind and the wind erosion sediment decline in sequence from wind speed,direction to frequency.But in the process of structural variation, the sequence of the correlation relationship is wind direction,speed and frequency.(3)In the process of random variation,the relation (R~2=0.9164)is closer than that in the process of structural variation (R~2= 0.6526)between the drift potential(DP)and the wind erosion sediment.But it is opposite between the resultant drift potential(RDP)and the wind erosion sediment.It is not obvious(R~2=0.0745)in the process of random,while it is very close (R~2=0.9343)in the process of structural variation.(4)The wind erosion sediment is patchy distributed in the process of random variation,but concentrated distributed with the zonation in the process of structural variation.
