Key Problems Impacting the Development and Utilization of Irrigation Region Groundwater and Their Solutions

According to the practical problems and the impacts on economic,social and ecological environment in the process of development and utilization of irrigation region groundwater,particular in the north of our country,the reasonable necessity was discussed in this paper.Based in all kinds of theoretical researches and equipments development current situation in domestic and abroad,key technologies of groundwater in irrigation region are suggested,they including the technology of groundwater bearing capacity and appropriate exploitation,the new filter structure and well-forming treatment as well,efficient well repair,the intelligent monitoring of groundwater and surface water combined dispatching and so on.Aiming at the above key technologies,the corresponding solutions of sustainable development and utilization groundwater resources in large-scale irrigation region were formulated to meet a new stage,so as to provide a certain amount of technical support for reasonable development,efficient utilization and benign cycle of groundwater resources in irrigation region.
