摘要
根据2002-2006年宝鸡峡塬上、塬下灌区内典型井观测资料,分析地下水的时空动态特征;利用灰色关联度理论分析地下水变化的主要影响因素,得出影响地下水动态的主要因素为降水、灌溉和开采;并在此基础上建立了GM(1,1)模拟地下水动态演变规律,模型精度较高。研究结论可为宝鸡峡灌区地下水调控提供依据。
The article is based on the typical observed data in the irrigation area of the top and lower of loessial plateau in Baojixia from the year of 2002-2006 and analyzes the spatio--temporal dynamic characteristics of groundwater. It studied the main rel0ted factors which influenced the groundwater dynamic variations by the theory of grey correlation, which the main factor is precipitation, exploitation and irrigation. Therefore, it was set up to simulate the groundwater dynamic evolvement regulation and the precision of the model. The results could be used to regulate groundwater level in the Baojixia irrigation area.
