摘    要:在特定的时间和空间尺度上,某一区域的土地退化(如盐渍化等)及演变必然会导致该区域范围内土壤特性的空间变异性。本文运用RS/GIS技术,采用相关分析、传统统计学和地统计学相结合的方法,分析渭一库绿洲土壤含盐量、矿化度、电导率、含水率、PH值、八大离子等土壤特性的时空变异情况,揭示其绿洲土壤特性的时空变异规律及相互之间的关系,以便更准确地了解土壤特性时空变异和区域生态环境之间的关系。

关 键 词:渭-库绿洲  盐渍化土壤  时空变化

Spatio-temporal Character of Soil Salinization in Weigan-Kuqa Oasis

Abstract:Land degradation (e. g. salinization) and its evolution in a given region will inevitably cause the variability of soil characteristics in specific temporal and spatial scales. In this paper, we used RS/GIS technology with the combination of correlation analysis, traditional statistics and geostatistics methods. We analyzed the temporal and spatial variation of soil properties, such as soil salinity, conductivity, moisture content, pH value and the eight ions. This can be a scientific basis for the rational use of land resources, better understanding of the soil structure and function, reasonable use of water resources in irrigation, soil salinity control and improvement, and thus can contribute to the eco-environmental stability protection in Weigan-Kuqa Oasis.
Keywords:Weigan-Kuqa Oasis  saline soil  temporal and spatial variation
