新疆伊犁河谷地下水系统划分及特征研究

Classification and Characteristics of Groundwater System in Yili River Valley of Xinjiang

地下水系统划分是正确评价和合理开发利用地下水资源的基础,也是区域地下水规划的重要依据。以地下水系统理论为指导,以伊犁河谷地下水系统为研究对象,在全面分析研究区地形地貌、地质、水文地质条件基础上,依据地下水系统划分原则,将伊犁河谷地下水系统划分为2个一级地下水系统,7个二级地下水系统,并对一级、二级地下水系统特征进行了初步总结。通过对研究区地下水系统划分,为伊犁河谷地下水资源规划提供了科学评价和理论依据,对我国西北干旱-半干旱地区地下水系统研究具有实际参考价值和借鉴意义。

Groundwater system study is an important base to assess regional groundwater resources and to set up the rational groundwater development patterns.Based on the topography and geomorphology,regional geological conditions and hydrogeology conditions of the Yili River Valley,the groundwater system in the Yili River Valley was divided in taking the systematic theoretical analysis of groundwater.According to the principles of groundwater system division,the groundwater system can be divided into two the first grade and seven second grade groundwater system,and the characteristics of the first and second groundwater system are summarized.The division of groundwater system has important theoretical and practical significance for groundwater resources of Yili River Valley,and the research has the practical reference value and referentical significance in the arid and semi-arid area of Northwest China.
