摘要
To improve the reliability of regional groundwater resource assessment and to apply the theory and method of ecology-oriented regional groundwater resource assessment in arid and semi-arid area, the research on the relationship between groundwater and ecology environment in Junggar Basin and Ordos Basin is carried out, and the result reveals that groundwater takes significant ecological value. Nowadays it takes inadequate consideration on the ecological value of groundwater in groundwater resource assessment in arid and semi-arid area, which is one of the reasons for inaccurate groundwater resource assessment. The concept of groundwater ecological value is constructed in arid and semi-arid area.
