Optimize The Allocation Of Water Resources Research In Chaoyang

Chaoyang city is one of the important cities of liaoning province, high degree of development and utilization of water resources, water contradiction is more outstanding, the rapid growth of social economy make the chaoyang city needs more water resources, the serious problem of the contradiction between supply and demand of water resources.Inter-basin water diversion project development has greatly enriched the chaoyang city water supply source, therefore, to study water resources optimal allocation in chaoyang chaoyang city social economy ecology coordination for sustainable development has a certain theoretical and practical significance.Inter-basin water diversion project development as the background, the new increase in water diversion and back, in view of the general plan and water saving, set up 75% reliability under 2020,2030 chaoyang city water resources optimal allocation model.The main content of the article is as follows:(1) The introduction of water poverty index and water pressure index to evaluate water resources situation in 2012 in chaoyang, chaoyang water poverty index was 34.9 in 2012, in the unsafe state of water resources;Chaoyang city water resources per capita is 452.4 m3 person, less than the water level threshold of 1000 m3/person, a serious shortage of water in chaoyang city.(2) According to the development of chaoyang city planning and the related theory of water demand prediction, draw up water quota of water consumption departments on different planning years, through the quota method to predict the water demand of different water department, Get under the assurance rate of 75%,2020 2030 under the general plan of water demand in chaoyang, respectively are 864.50 million m3,1.026821 billion m3, Water-saving scheme of water demand is 775.64 million m3,929.07 million m3.Combined with the water resources development and utilization in chaoyang, incorporating the diversion and back to the increase of the water, the supply amount of 2020,2030 are 0.836 billion m3,0.9988 billion m3.Under the general solution is obtained by analysis on the balance of three times, 2020,2030 water deficit are-2.452 million m3,3.805 million m3.Water saving scheme under water in 2020,2030 years are 61.309 million m3,69.806 million m3.(3) Based on the related theory of optimized allocation of water resources,Introduce sustainable development coordination index. establish a social benefit, economic benefit, ecological benefit comprehensive benefit as the goal model of multi-objective optimization allocation of water resources in chaoyang using matlab software to solve multi-objective model, Results show that under the 75% reliability, general scheme mild water shortage problems in chaoyang,2020,2030 water rate are0.00%,0.38%.mainly for agriculture, industrial water;Under water saving plan there is no shortage of water, and after the configuration, groundwater use decreases, it would be helpful for the sustainable utilization of water resources in Chaoyang.
