湖南洛塔饱水岩溶带地下水动态分析

Groundwater Dynamics Analysis of The Saturated Karst Zone of Luota in Hunan Province

湖南洛塔为一典型的溶丘洼地型岩溶区。本文利用近几年水环境监测资料,进行饱水岩溶带地下水的动态研究,认为影响岩溶地下水动态变化特征与降水、生态环境和土地覆盖程度等因素相关。降雨强度与地下水动态变化量呈正相关关系;植被、土壤的覆盖程度与地下水的动态变化幅度、降雨动态滞后时效性呈正相关关系。

Hunan Luota is a typical one of Karst billabong Terrain.The article is based on some monitoring data of water environment in recent years and studies groundwater dynamics in the saturated zone. It is concluded that the groundwater dynamics is evidently related with some factors,such as precipitation,ecological environment and land covering degree.The variation of groundwater dynamics is evident positive related to the rainfall intensity.The covering rate of vegetation and soil is positive related to groundwater dynamic variety range and rainfall dynamics delay time effect.
