西安市主城区地下水位动态类型划分研究
Study on division of groundwater dynamic type in main urban of xi'an
摘要
Abstract
In order to understand the spatial distribution of groundwater level dynamic type in the central areas of Xi'an, based on different hydrogeologic units , the paper selected groundwater depth data of 15 typical monitoring wells ,and used principal component projection-clustering ( PCP-C) model which is based on nonlinear transformation to study groundwater level dynamic type in different regions .The results showed that the groundwater dynamic types overall study area can be divided into types of hydrological in -fluence and mining influence .The influence of hydrological factors ranging from flood plain to second-or-der in non-mining areas change gradually from strong to weak;loess tableland ,self-supply well mining ar-eas and water source concentrated mining areas are greatly influenced by human activities and these areas belong to the type of exploitation influence .关键词
