在干旱区绿洲平原地带,地下水埋深与土壤盐分时空分异明显,且二者存在高度的交互耦合关系。为实现分时段、分区域对地下水进行综合利用及对土壤盐渍化进行有效治理,以克里雅绿洲为研究区,根据20个地下水样点及8个土壤样点的监测数据,采用经典统计学方法、地统计分析法及GIS技术对研究区地下水埋深与土壤盐分的时空分异进行了研究,并运用耦合系数模型计算了二者之间的耦合度。结果表明:地下水埋深夏秋季较深,冬春季较浅且研究区西北浅,东南深,由西北向东南递增;土壤盐分含量夏秋季快速下降,冬春季迅速上升且研究区西高东低,由西向东呈条带状递减分布;地下水埋深与土壤盐分含量之间存在交互耦合的关系。
In the arid plain oasis plain, the spatial and temporal distribution of groundwater depth and soil salinity are obvious, and the two have a high degree of mutual coupling. In order to realize the comprehensive utilization of groundwater and the effective control of soil salinization in different time zones and sub-regions, and based on the monitoring data of 20 groundwater samples and 8 soil samples, The spatial and temporal variability of groundwater depth and soil salinity in the study area was studied by means of geostatistics, geostatistics and GIS, and the coupling degree between them was calculated by using the coupling coefficient model. The results show that the groundwater depth is deeper in summer and autumn, shallow in winter and spring, shallow in northwest, deep in southeast, increasing from northwest to southeast. Soil salinity decreased rapidly in summer and autumn, There is a decreasing distribution from west to east. The relationship between groundwater depth and soil salinity is interaction and coupling.
