红旗农场地下水对土壤盐分分布影响预测研究
Predictive study on impact of groundwater on soil salinity distribution in Hongqi Farm
摘要
Abstract
In order to investigate the effects of changes in groundwater depth and mineralization on the spatial transportation of soil salt,Hongqi Farm of the Third Division of Xinjiang Production and Con-struction Corps was selected as the research area and the GMS-HYDRUS-2D(groundwater modeling system,GMS)model was constructed to predict the changes in groundwater and soil salinity at three characteristic points in the study area from 2023 to 2035 based on the field monitoring groundwater and soil salinity data from 2021-2023.The research results show that groundwater changes are cyclical,the groundwater depth shows a decreasing trend,while the mineralization of groundwater and soil sali-nity show an increasing trend.The root mean square error of the GMS-HYDRUS-2D coupling model is less than 0.250 0,the Nash efficiency coefficient is greater than 0.700 0,and the determination coeffi-cient is greater than 0.660 0,which indicate that the model has a good fitting effect and can present the changing trend of soil salinity under the action of groundwater.At the end of the simulation period in 2035,the groundwater depths of wells 1,4 and 5 decrease by 0.44,0.63 and 0.52 m,respectively,compared with the same period in 2023,and the salinity of the soil surface layer in the sampling points 3,8 and 9 increase by 0.27,0.87 and 0.36 g/kg,respectively.Additionally,the decrease in ground-water depth positively correlates with the accumulation of soil surface salt.The research results can pro-vide theoretical support and scientific guidance for the formulation and application of the program to im-prove soil salinization in Hongqi Farm in southern Xinjiang.关键词
