The Establishment And Study Of The Balance Sheet System Of Water Resources

The balance sheet of natural resources is based on the traditional accounting mode,record all China area or a China area of natural resources,understanding at a point in time on the status of natural resources,reflecting the change trend and the number of natural resources,the value of assets within a certain period of time.After clarifying the natural resources of family,through the standard outgoing audit of leading cadres,and for environmental protection and ecological civilization construction work formed a forced mechanism useful.(1)In the study of relative assets and liabilities of river water resources,based on the prior probability of the river rainfall runoff relationship and the two-dimensional Archimedean Copula function of the maximum posteriori probability,the relative assets and liabilities of the water quality in the Xiaoqing River Basin are evaluated.The distribution of runoff and rainfall in Xiaoqing River Basin obeys Gumbel and Pearson III distribution respectively,and its joint distribution obeys Gumbel-Hougaard Copula function.By estimating the prior probability of Xiaoqing River Basin,we calculated the variation point of rainfall runoff relationship based on the maximum a posteriori probability in Xiaoqing River Basin in 2005.The joint distribution probability C1 and C2 of water quality and water quality before and after the abrupt point are calculated,which shows the increasing trend in time,which indicates that the control level of the Xiaoqing River Basin is increasing,the probability of water quality and water quality is increasing,which indicates that the relative net assets of river water resources are increasing.On this basis,the asset growth coefficient alpha is defined and its value increases faster in 2013.On the one hand,the reason is that the water quality of the Xiaoqing River is poor and the effect is obvious.On the other hand,the better the water quality is,the more difficult it will be.Therefore,after 2014,the coefficient of growth of assets is flat.In conclusion,the river water resources relative asset liability assessment method has evaluated the water resources and water quality of rivers from multiple perspectives,and is consistent with the actual situation.(2)In the study of absolute assets and liabilities of river water resources,the calculation method of absolute assets and liabilities of river water resources,considering water quality and water,is put forward.Calculate 2008-2013 river water resources static net assets were-26.6 billion,-10.2 billion,m3 m3-4.7,-12.9 m3,m3 billion billion billion billion-1.1 m3,-0.7 m3.The overall trend,decreased with the increase in liabilities of river water resources assets,show that in recent years the Yihe River Basin water quantity and water quality gradually improved.At the same time,as the river water resources evaluation more objective management quality,using the precipitation anomaly exclude the interference of rainfall on the calculation results,the dynamic balance of the net assets of water resources rainfall influence the further calculation of the 2008-2013 river water resources dynamic net assets of-16.0 billion,-15.6 billion.M3 M3-5.3 m3,-11.6 billion billion m3,80 million m3,-0.8 million m3.In the balance of the influence of rainfall conditions,the quality and quantity of Yihe River is still improving,that in recent years in the river water resources quantity and quality management properly.(3)In the study of relative assets and liabilities of regional water resources,the evaluation index system of sustainable development of regional water resources in Shandong Province Based on water footprint is constructed.The relative advantage theory is used to quantitatively evaluate the relative assets and liabilities development of water resources in 17 cities of the province,and the strong and weak rows of the overall sustainable development ability of these geographic units are obtained.Order.The results of 2 places,such as Weihai and Yantai,are the strong sustainable development type.The results of the 6 evaluation results of Zibo,Qingdao,Binzhou,sunshine,Dezhou and Zaozhuang are strong in sustainable development,and the 7 evaluation results of Laiwu,Jining,Weifang,Dongying,Linyi,Tai'an,etc.are weak sustainable development.2 places in Liaocheng and Heze.(4)In the study of the absolute assets and liabilities of regional water resources,the water resources assets are divided into 2 parts of the basic value of water resources and the ecological compensation for water resources.The water resources liabilities are divided into 3 parts of the water environment decline cost and the water resources ecological compensation.The water resources of Ji'nan city from 2011 to 2015 are calculated by using different mathematical and economic models of the game theory.Source assets and liabilities.From 2011 to 2015,the total assets of water resources in Ji'nan were 791 million yuan,731 million yuan,782 million yuan,735 million yuan and 714 million yuan respectively.The total liabilities were 645 million yuan,664 million yuan,743 million yuan,786 million yuan and 858 million yuan respectively.The net assets were respectively 146 million,67 million,39 million,-0.51 billion,and-1.44 billion yuan.Study of Shandong water resources balance sheet to provide a theoretical basis and methods for the improvement of water resources in Shandong province and evaluation method of water resources management,and improve the existing environmental management system of water resources in Shandong Province,to provide reference for the comprehensive management of the sustainable development of water resources in Shandong province and China's River basin.
