Water resource is an important resource for human survival and social development.However,with the rapid development of social economy,People's livelihood and social development are more dependent on water resources,We ignore the protection and effective of water resources.The problem of water resources brought by the rapid economic development has become an urgent problem to be solved,The balance of supply and demand of water resources has become an important factor restricting the further development of social economy.Zhaozhou county is a famous grain production place in china,Agriculture and industry have developed rapidly in recent years,With the increase in water consumption,there is a shortage of water resources.Based on the study of the existing water resources carrying capacity,On the basis of studying the relationship between water resources system and social economy,agriculture and life,Using system dynamics method,according to the actual situation of Zhaozhou County,according to the principle of system dynamics,divided the water system of Zhaozhou County into agricultural water subsystem,industrial water system,water system and water resources subsystem,using VENSIM software,established by the 3 state variables,3 variable rate,10 table the function and the 12 feedback loop of Zhaozhou County water resources carrying capacity system dynamics model.In the analysis of 2009-2014 in Zhaozhou county and the development and utilization of water resources based on the characteristics of change,selection of industrial water quota,agricultural water quota,the population growth rate,sewage with multiple variables such as rate of scenario simulation SD model to simulate the decisionvariables on the bearing capacity of water resources in Zhaozhou county.The water resources on the complex relationship between economic and social development restrict each other through a variety of scheme comparison,select the optimal scheme to water saving,pollution control as the focus,Zhaozhou county put forward to the comprehensive coordinated and sustainable development of the water recommendations.This paper provides some theoretical basis for the scientific development and utilization of regional water resources and optimization of water resources management.
