中文摘要	荒漠盐生植物作为艾比湖湿地广泛分布的植物类群,其影响下的土壤养分和盐分的变化特征,对于研究盐生植物适应盐渍化环境的机理有着重要意义。基于2012和2013年对艾比湖湿地3种不同生境(灌丛生境、草甸生境、稀疏乔木生境)进行野外调查,采用传统统计学方法与地统计学方法,对土壤养分和盐分特征进行了初步探究。结果表明:(1)灌丛生境-草甸生境-乔木生境,随湖距和海拔高度的增加,土壤有机质、全氮和全盐含量显著升高(P<0.05);(2)表层0~5 cm土壤聚盐和聚养现象极为显著(P<0.01),且呈上高下底分层结构;(3)灌丛生境-草甸生境-稀疏乔木生境,土壤有机质、全氮和全盐均具有明显的空间结构特征,且空间分布不均,其空间异质性主要由结构性因素如微地形、湖面积波动、成土母质、气候变化等引起,以条带状和斑块状镶嵌分布;(4)通过对3种不同生境土壤养分和盐分的回归分析表明,土壤有机质含量的变异性是影响土壤全氮变异性分布的重要因子,而土壤盐分异质性的存在,在一定程度上又是引起土壤有机质和土壤全氮异质性的重要因素。
英文摘要	Desert halophytes are the plant groups which are widely distributed in Ebinur Lake Wetland. Under their influence, the change features of soil nutrient and salinity are of important significance to researching the mechanism that halophytes adapt to salinization environment. Based on the field survey on 3 different habitats (shrub habitat, meadow habitat, sparse arbor habitat) in Ebinur Lake Wetland in 2012 and 2013, elementary exploration was carried out on soil nutrient and salinity by using traditional statistical method and geostatistic method. The results showed that: (1) soil nutrient and salinity had significant elevated with increasing of the altitude and the distance from the lake under three different types of habitats. (2) the salt and nutrient accumulation in topsoil at the depth of 0~5cm were extremely significant, and the hierarchy was formed with higher high and lower low. (3)The soil organic matter, total nitrogen and total salt had the significant spatial structure feature and the uneven spatial distribution. The reason mainly lied in the micro topography, Fluctuation in Ebinur Lake Area, Parent material and climate changes and so on and distribution in the form of Strip and Patch; And (4) the regression analysis of the nutrition and salt in three different environmental soils displayed that, on the one hand, the variability of soil organic carbon was the key factor for the influence of soil total nitrogen,on the other hand, to some degree, the variability of soil salt was the important factor to effect the soil organic matter and soil total nitrogen.
