Research On Water Environment Security Assessment System And Sustainable Utilization Of Water Resources Of Hebei Province

Hebei province lies in the Huabei region where water resource is short.In Hebei," the shortage of water in water resource " and " the shortage of water in water quality " are both conspicuous, and the issues of Water Environment Security are extremely serious. Since the revolution and opening of China, the degree of exploitation and utilization to the water resource is higher and higher following the high-speed development of social economy. It has even reached the hypernormal stage and has already caused the complexion of water quatity sharply reduced not only native but also in and out. Especially, the excessive exploitation of groundwater has already brought about the dropping continuously of groundwater level and caused a lot of geology issues or environment calamities, for example, ground crack, funnel caused by falling of groundwater level.At the same time lot of wastewater was discharged without treatment especially high polluted enterprises such as paper mill, tannery and print works because of lacking of environment consciousness. And this made water bodies pollution and sharpened water resources shortage and influenced water environment security.This analyzed water environment actuality and problems of Hebei Province, and expatiated the contents, characteristics and significance of water environment security. Based on the theory of AHP and grey relating degree, water environment security assessment system was established. This paper assessed water environment security of Hebei Province by establishing and predigesting calculation model. Aiming at the water resources actuality of Hebei Province, water demand and supply amount were forecasted and demand and supply balance was analyzed, also analyzed and forecasted the actuality of pollutant discharged. According to the theory of sustainable development, this paper analyzed the water resources loading actuality and put forward the technology an supporting system of water resources sustainable utilization. Finally water environment security and water resources sustainable utilization of Baoding City was assessedThe results show that the security degree value of eco-safety, water quality safety and water quantity are all lower than national average, especially water environment security degree is serious and is in the end of all the regions, water quality and quantity crises are existed.The results of water demand and supply balance and pollutant amount forecast show water resource supplied is lower than demanded. The second analysis can reach the balance with water transportation from southern to northern area. The sewage influence water environment security gradually serious and industrial wastewater in the reverse.The research on technology and measures of sustainable utilization of Hebei Province shows that water resources of Hebei Province can achieve sustainable utilization with effective treatment technology and supporting system.The assessment of water environment security and sustainable development of Baoding City shows the situation of Baoding City is better than that of Hebei province. Water quantity is serious and the water supply can't satisfy the demand. Also the influence from domestic sewage is gradually serious however industrial wastewater is in the reverse. Water environment security and sustainable development of Baoding City can be achieved with effective countermeasures.The result of this paper can make people know the status of water environment security of Hebei Province, and also know the water resources loading capacity and countermeasures of water resources sustainable utilization. It can providing references to government for making policies and countermeasures of water environment and water resources. Finally it can direct Hebei and other provinces to improve water environment and assess water environment security and achieve sustainable development of water resources.
