The impacts of the weather environment variety on the stream runoff in the mountain area and the impacts of the human activity and hydrologic environment on the distribution and functions of water resources in the interior basin of Northwest China were analyzed.

An integrated water quantity and quality evaluation method has been set up for drainage basins,and the integration concepts of water resources functional capacity and water resources functional deficit have been put forward.

An integrated water quantity and quality evaluation method has been set up for drainage basins,and the integration concepts of water resources functional capacity and water resources functional deficit have been put forward.

According to the intrinsic relation between the function of groundwater resource and its sensitivity to pollution, this paper deals with the spatial relationship based on statistical analysis with Hufu plain as the study area.

Based on the analysis of resources structure and resources function,this paper discussed the syslematic transformation theory by taking the function mutual transformation and the structural corresponding transformation.

In this model,the resources function,ecological function and geo-environmental function of groundwater were evaluated,and the sustainability of the groundwater function in the study area can be handled.
