中文摘要	选择克里雅绿洲喀尔克乡西部的一块带状芦苇地为研究区,在研究区内布设28个样点,采集芦苇覆盖度、株高、冠幅长、冠幅宽和密度这5个生长指标,分010,1030,3050cm三层取土壤样品并测定各层的土壤含水量,在此基础上,利用描述性统计分析和地统计分析等方法研究芦苇分布区表层土壤含水量的空间变异特征。利用相关分析方法分析各层土壤含水量与芦苇生长指标之间的相互关系,为改善研究区脆弱生态系统提供理论依据。从描述性统计分析来看,芦苇分布区三层土壤含水量的变化幅度均较大,各层均表现为中等变异强度。随着土层深度的增加,土壤含水量逐渐增加,但其变异程度逐渐减小。土壤含水量垂直分布特征有4种:即底聚型、中聚型、表聚型、表聚型和底聚型混合等。底聚型土壤含水量剖面为研究区最主要的剖面类型,其次是中聚型土壤含水量剖面,再次是表聚型和底聚型混合的土壤含水量剖面,表聚型土壤含水量剖面的分布面积最小。土壤含水量与芦苇生长指标之间的相关分析表明,各层土壤含水量与芦苇生长呈正相关关系。其中各层土壤含水量对芦苇覆盖度、株高和密度的正面效应不太明显;对芦苇冠幅长和冠幅宽等生长指标的促进作用较明显。下层土壤含水量相对于上层土壤含水量而言,对芦苇生长起到更重要的促进作用。
英文摘要	A zonal reeds land located in western part of Karki Village in Keriya Oasis was chosed as a study area, 28sample points were arranged,the reeds,growth indices such as coverage,height,crown length, crown width and density were collected,three soil layers 010,1030,3050cm was apareed to take the soil samples.On the bases of soil moisture data,the spatial variability of soil characteristics of reeds land was studied by using the descriptive statistical analysis and geostatistical analysis.And then,the relationship between soil water content in each layer and the growth of reeds was analyzed by using the correlation analysis in order to provide a theoretical base for improving the weak ecosystem of the study area.It could be infered that soil moisture on three layers exhibited medium spatial variability based on the descriptive statistical analysis.Soil moisture increased with the increase of soil depth,but the degree of decreased.Characteristics of vertical distribution of soil water content had four distribution types including the bottom assembled type, medio-assembled type,surface assembled type and combination of bottom and surface assembled type.Bottom assembled type was the major soil moisture profile type in this area,followed by the medio-assembled type,then combination of bottom and surface assembled type,the distribution area of surface assembled soil water content profile was the minimum.Correlation analysis between growth of reeds and soil moisture showed that the amount of soil water of each layer and reed growth was positively correlated.The positive effect of soil water content on the growth of reed cover,plant height and density was less obvious compared to its effect on reed crown length and crown width.Soil water content in deep layer played more important role than soil water content of upper layer in promoting the reed growth.
