Strategy of Water Resources Protection for Guishui River, China
In the Yanqing area, Beijing, China agriculture water use and soil erosion are significantly serious due to large-scale agricultural irrigation; It has been the most prominent issue of agricultural irrigation for water resources protection, mainly because irrigation water use utilization efficiency is very low. The key issue of water-saving agriculture is to improve the utilization of irrigation. In this research, Guishui River in Yanqing County, Beijing with water eco-system protection function has been selected as the study location which experiences period of drought and wetness annually. Based on the hydrology methodology and support of the field surveys and continuous observation means for hydrology environmental elements, combined with experiments of vadose zone water transport mechanism, integrated multiple geo-information technology and methods, the research would obtain valuable long-term multiple spatial and temporal scale quantity data on water and environmental concerns. Understanding of quantitative mechanism-based research methods, it is very important not only for scientific theory, but also helps to address natural and artificial groundwater recharge mechanisms, drainage analysis and a series of theoretical and practical problems for water-saving agriculture. Moreover, for evaluation of regional water resources system, it is of great practical value to develop a scientific and rational irrigation system for Guishui River in Beijing area. It is of great significance to establish a regional sustainable development pattern for balance of regional development and protection of water resources.
