For this reason , to analyze the spatial and temporal dynamic of ground water table and water quality beneath the typical phytocommunity in particular areas , will be helpful to probe into the dynamic formation of soil moisture and salinity , and to understand the spatial variation of vegetation 因此，分析区域内典型植物群落的地下水水位、水质在时空上的动态变化，有助于探讨土壤水盐动态变化的形成条件，揭示植被在空间上梯度变化的原因。
