摘要
以整个莱州湾南岸区域作为研究对象,运用经典统计学和地统计学相结合的方法研究了该区2007-2009年浅层地下水埋深及矿化度的空间变异特征,并绘制了其空间分布图。结果表明:地下水矿化度和埋深在东西和南北两个方向都呈二阶趋势效应,具有强的空间自相关性,说明主要受自然因素影响;kriging插值表明:离海岸线距离越近地下水矿化度越大,地下水埋深表现为西南部较深,而东南部和西北部较浅,地质构造、河流及海水入侵等自然因素作用是形成该空间格局的重要因素。地下水特征的空间结构性和定量化研究对莱州湾南岸地区地下水资源评价和区域水盐迁移调控有着直接的现实意义。
Taking south coast of Laizhou Bay as the study object,the spatial variability of shallow groundwater table and mineralization in 2007-2009 of this area was studied using the combination of classical statistics and geostatistics method,and the spatial distribution map was drawn.The results showed that groundwater table and mineralization presented second order trend effect in both East-West and North-South directions and had a strong spatial autocorrelation,demonstrating it mainly influenced by natural factors.The kriging interpolation showed that the closer from the coastline,the higher mineralization of groundwater,and groundwater table presented that the southwest was deeper,and the southeast and northwestern were shallower;the natural factors of geological structures,rivers,and sea water invasion were the important factors that formed the spatial pattern.The spatial structure characteristics and quantitative research of groundwater features had a direct practical significance on groundwater resource evaluation and regional water and salt migration of south coast of Laizhou Bay.
