Spatial Interpolation Method Preferences and Influencing Factors of Groundwater Depth Interpolation in the Kriya River
摘要
Abstract
In order to select an appropriate interpolation method to reveal the spatial variation characteristics of groundwater depth in the arid oasis,53 groundwater monitoring well sample points were selected to be taken as the study area,and three interpolation methods,including spline function method,inverse distance weight method and kriging method,were used to interpolate the groundwater depth of the monitoring wells,and the cross-validation method was selected to verify the interpolation effect,and the factors affecting the spatial distribution of groundwater depth in the Keriya River were qualitatively analyzed.The results show that from 2019 to 2021,the groundwater depth of the tail oasis gradually increases from southwest to northeast with time,and the groundwater depth of the desert section is smaller in the south and north and larger in the middle,and the groundwater depth in the Yutian oasis is smaller than that in the tail oasis and the desert section.In 2019,2020 and 2021,the average groundwater depth of the desert section is 4.64 m,4.08 m,2.78 m;4.80 m,4.22 m,2.88 m;4.86 m,4.10 m,2.87 m.The kriging method is the optimal method for spatial interpolation of groundwater depth in arid areas,and the oasis vegeta-tion cover,transpiration and human activities are important factors affecting the groundwater depth of the Kriya River.关键词
