The Analysis And Calculation On Water Resources Carrying Capacity Of Hebei Province

Water is not only a precious resource, but also one of matter bases of human's society unremitting develop. Water resources have potential ability to sustain economy develop of society to a certain extent except absolutely necessarily survival needs to people live. It means water resources not only have the ability of carrying capacity to people, but also to economy including industrial develop scale and agricultural irrigate scale. And then the concept of carrying capacity is accepted by people gradually and apply to others concerned aspects, so study on water resources carrying capacity also emerge as the times require. Water resources carrying capacity is an important compose part of natural resources carrying capacity and a key index to able or not to sustain harmonious develop of population economy and environment in lack of water resources region.Study on water resources carrying capacity in Hebei province has very important meaning to develop layout of civil economy protect entironment and water resources durative utilize. Water resources as the most important restrict factor of society economic develop to Hebei province, its carrying capacity belongs to research category of continuable. In this paper, the author bring water resources carrying capacity problem of Hebei province into complex-giant system, according to the characteristic of water resources exploitation and utilization in Hebei province, and the relations among population water resources environment and development. Futher, a multiply objective decision-making analysis model for the water resources carrying capacity research on Hebei province is set up in term of sustainable development. To solve the model, Tchebycheff method as a new tool is introduced, and complete compiling procedure work of mutual Tchebycheff multiple objective decision-making analyse cource.The primary concents of this paper as follows: ①Recommend academic study of water resources carrying capacity, analyse historical develop status of water resources carrying capacity and summarize the investigative method,characteristic,meaning and basal principle of water resources carrying capacity.②Recommend the calculational method for water resources carrying capacity, analyzes the water resources carrying capacity's academic basic and establish mathematical models of water resources carrying capacity.③ Recommend the method to solve multiple objective model of water resources carrying capacity.④Calculate the water resources carrying capacity of Hebei province in the year of 2010 and 2020 and analyse the calculative result.⑤Aiming at the actual circs for water resources carrying capacity in Hebei province, the author brings forward some materialmeasures to improve the water resources carrying capacity for Hebei province.The results proved it is feasibility for the model to analysis water resources carrying capacity on Hebei province. It also demonstrated that the model can be high efficiency mean for forecasting and optimization of social-economic development and environment protection on Hebei province and offer definite references and ways for water resources sustainable utilization research on Hebei province in the future.
