河北省農(nóng)村飲水現(xiàn)狀評(píng)價(jià)與保障機(jī)制研究
[Abstract]:The problem of drinking water safety in rural areas of Hebei Province has always been serious. According to the unsafe factors of rural drinking water in Hebei Province and the policy and policy of the state determined to improve the situation of rural drinking water, the rural safe drinking water project in Hebei Province emerges as the times require. At present, there is still a lack of systematic evaluation method of rural drinking water situation and rural drinking water safety guarantee mechanism in China. Based on the survey data, this paper discusses the evaluation method of rural drinking water situation and the mechanism of rural drinking water safety guarantee. This paper describes in detail the present situation of rural drinking water in Hebei Province from five aspects: water source, water supply mode, water supply quality, sewage treatment and reuse and water price setting, and creatively selects the present water quality index from which the effective data are extracted. The present situation index of water quantity, the present index of convenience and the index of guarantee rate are used as the evaluation parameters of rural drinking water in Hebei Province. Firstly, the corresponding weight of the sub-parameters to which each evaluation parameter belongs is determined, and the value of each evaluation parameter is calculated by using the multi-factor comprehensive index method, and then the relative important relationship among the evaluation parameters is judged. The corresponding weights of each evaluation parameter are calculated by fuzzy analytic hierarchy process (AHP). Finally, the comprehensive index of rural drinking water in Hebei Province is calculated by using the multi-factor comprehensive index method again. This paper makes a digital expression of the present situation of rural drinking water in Hebei Province. The improvement level of infrastructure was represented by the penetration rate of rural tap water in Hebei Province, and the correlation between the per capita GDP of each region and the penetration rate of rural tap water in each region was analyzed. It is found that the per capita GDP of each region is positively correlated with the penetration rate of rural tap water in each region, and the present situation of rural water quality and water quantity in each region is negatively correlated with the penetration rate of tap water. Considering the relative advance and lag relationship between the per capita GDP of each region and the penetration rate of rural tap water in each region, the priority levels of rural financial support and policy tilt in Hebei Province are determined. Based on the sensitivity analysis of the influencing factors of drinking water in rural areas of Hebei Province, the sensitivity of each influencing factor to the present situation of drinking water was determined and divided into three categories: natural category, man-made category and natural-man-made category. According to the results of sensitivity analysis, it can be found that the natural and man-made factors are the most sensitive to the present situation of drinking water, followed by the natural factors, and the human factors are again, which proves that human activities should actively follow the laws of nature from the philosophical and ecological aspects. Further classification of engineering attributes is carried out, and each sub-project attribute of rural safe drinking water project in Hebei Province is divided into three categories: basic, extensibility and companionship. According to the results of sensitivity analysis and the division of engineering attributes, the priority level of each sub-project in rural safe drinking water project in Hebei Province is determined. Starting from five aspects of water quality, quantity, convenience, guarantee rate and long-term operation mechanism to solve the problem of drinking water safety in rural areas, this paper introduces the solutions to all kinds of drinking water safety problems. This paper systematically discusses the mechanism of rural drinking water safety guarantee in Hebei Province, which provides theoretical basis and technical support for the implementation of rural safe drinking water project in Hebei Province.
