In order to solve water resources problems in the North China Plain, this paper explored human-nature compound water circulation system from three aspects including urban flood control, surface drainage and saline water in the central and eastern of the North China Plain. Results show that: (1) The technical methods have achieved zero increase in rainwater runoff in urban areas, (2) surface drainage depletion problems can be solved through abandoned water and river water separation method, (3) and technical method through promoting rainwater infiltration would be used to solve problem of saline water in the central and eastern parts. This research provides a new perspective to the ultimate solutions to water resources problems in the North China Plain, and a fresh research direction for the development of hydro-geological science.

The risk of groundwater contamination following the infiltration of waste surface water, is of great interest, particularly in areas experiencing water shortage. In this study, the distribution characteristics of contaminants along the Cihe River, in the piedimont plain of the Taihang Mountains, China, was investigated by measuring the soil and water samples. The main organic contaminants detected in different media include hydrocarbons, chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, and pesticides. The main contaminants found in different media are mostly derived from the river water, which can be seen from the results of waste water from the river and groundwater, from the soil samples from different depth and distance of the profiles along the river. The distribution characteristics showed that there has been a natural attenuation of the contaminants from the river during their transportation through the soils and groundwater. The sorption of organic compounds to soil organic matter is thought to be a main mechanism of natural attenuation.

The continued sustainable economic development of china depends in part, to the scientific management of China’s precious groundwater resources in the coming years. Groundwater resource scarcity is a common underlying problem across China, in addition, the large-scale groundwater exploitation for human consumption over recent decades has resulted in a series of environmental geological problems. As a result of these problems, the national economics in china have been seriously affected. In order to prevent groundwater resource exhaustion and environmental geology deterioration, “accurate control of groundwater resources (ACGR)” theory and its support system were established in this article, and the related prevention measures of the ACGR theory, such as accurate irrigation, accurate supply water, and accurate subsidies, were proposed. This paper highlights the ACGR theory as an efficient and essential way to achieve the sustainable groundwater resource management, which can be applied to countries such as China.
