Analysis Of The Water Resources Carrying Capacity And Joint Optimization Allocation Of Water Resources In Heilongjiang Province

Water resources in Heilongjiang province is abundant, uneven distribution, According to the current situation of development and utilization of water resources in Heilongjiang Province,In this paper, in order to achieve the sustainable utilization of water resources in Heilongjiang Province as the guiding ideology,In order to achieve reasonable utilization of surface water and groundwater as the goal and on this basis, the main production areas of Sanjiang Province, Heilongjiang Province, the main grain producing areas of agricultural water,Of water resources are optimal allocation, sustainable utilization of resources in Heilongjiang Province, Sanjiang plain water cost reduction and surface water and groundwater combined ratio provides a certain theoretical basis.(1) By utilizing the present situation and the present condition of water conservancy proje ct of water resources development in Heilongjiang Province, find out the problems existing in the utilization of water resources development in Heilongjiang Province. Based on the analysis of the existing literature on water resources bearing force evaluat ion system, and combined of Heilongjiang province actual situation of water resources, Heilongjiang Province water resources carrying capacity evaluation index. Evaluation of water resources carrying capacity of different administrative regions in Heilongjiang Province Based on the support vector machine method. The results show that: Greater Khingan Range, Heihe City, Yichun City, Hegang City, belongs to the class I, the water resources carrying capacity is strong,Shuangyashan City, Jixi City, Qitaihe City, Mudanjiang City, Jiamusi city and Harbin city belong to the II level,The water resources carrying capacity is in the middle level, and Qigihar, Suihua and Daqing belong to the III level. The carrying capacity of water resources is weak. This conclusion p rovides guidance for the rational development of water resources in Heilongjiang province.(2) According to the relationship between water resources and environment, analysis and calculation of multi scale theory of ecological footprint of water resources in Heilongjiang Province Based on the ecological footprint of water resources in Heilongjiang, the scale is divided into two administrative regions, river basin, the province’s three scale water resources difference study, respectively, from the municipalities(regions) of the surface ecological water overall, groundwater, carrying capacity to the bearing basin ecological footprint and ecological capacity and ecological surplus, to the province’s ecological carrying capacity, ecological footprint, ecological footprint and ecological surplus in different accounts, from the multi region and multi angle calculation of the bearing capacity and the ecological resources in Heilongjiang Province, the ecological footprint, ecological surplus and other indicators, an d the corresponding analysis. From the overall, Heilongjiang Province is rich in resources, but the water resources ecological footprint demand has increased year by year, the water resources ecological carrying power is low in the year appeared ecological deficit;Heilongjiang Province, the development and utilization of space is larger, but the distribution of water resources in space is extremely uneven, strong bearing capacity of the northern hilly region, the development and utilization of water resourc es is low;Southwest region economy is relatively developed, bearing capacity is low, so in the southwest, especially water resources carrying the lower force Qiqihar City, Suihua City, Daqing city should increase the adjustment of industrial structure and consumption larger amount of water and serious pollution of the enterprise; The southeast region belongs to the plain area, it should adjust the grain planting structure in the agriculture, reduce the large amount of individual water demand, the planting scale of the crops with low quality;From the Heilongjiang province water resources ecological footprint account distribution can also reflect the change of the industrial structure of Heilongjiang province. Should according to municipalities bearing capacity continue to adjust the industrial; resources of Heilongjiang Province water mainly from precipitation and water resources bearing force and precipitation associated, in dry years, water resources reduce the carrying capacity of, leading to reduce the ecological surplus, on water resources sustainable utilization of the impact. With the development of economy and technology, the water resources ecological footprint per ten thousands yuan GDP decreased year by year, various regions of Heilongjiang Province on water resources utilization rate is gradually improving, based on should improve storage, extraction, water diversion capacity of Heilongjiang Province, rational use of surface water and groundwater, promotion of agricultural water-saving measures, promote the healthy cycle of water resources.(3) For example of Sanjiang Plain in Heilongjiang Province of major grain producing areas water resources optimal allocation of, maximum comprehensive benefit of agricultural planting structure of single objective optimization model is established, considering that agriculture sustainable development, the objective function of the model representing the economic, social and ecological aspects. In various crops planting area is determined, the rational allocation of water resources were studied to crop water cost minimum as the objective function, calculate the surface water and groundwater, the configuration optimization, not deterministic interval two stage stochastic programming model should be used in optimal allocation of agr icultural water resources in Sanjiang Plain, for decision makers to make more rational decision-making provide reference. The biggest advantage of this model is combination of United Dispatching of surface water and groundwater, while the introduction of water diversion and water cost as the cost of water and calculated under different scenarios under different inflow water allocation, Sanjiang plain water resources planning and management, provides the basis for decision making, help policymakers to save water, improve the efficiency of water use. This chapter gives the analysis of the optimal allocation of surface water and groundwater exploitation of interval, and use ratio range of surface water and groundwater, which after rational exploitation and util ization, has important reference value, provide more favorable theoretical basis for sustainable utilization of agricultural water resources in Sanjiang Plain policy of, is bound to the rapid development of grain yield in security at the same time, bring better to solve the shortage of water resources problems.To sum up, through the research and analysis of the force capacity of Heilongjiang Province, water resources, can have a general understanding of Heilongjiang Province Water Resources Development and utilization of the status quo, and the province’s water resources ecological footprint development trend. For the exploitation and utilization of water resources in Sanjiang Plain in the presence of surface water and groundwater use proportion coordinatio n and groundwater exploitation and utilization of water resource cost higher problem, the interval of the two stage stochastic programming uncertain model of water resources optimal allocation to carry on the example analysis, based on proposed different optimization objectives, the water resources development and utilization ratio, Sanjiang plain water resources sustainable utilization and protection of regional benefit optimization provide theoretical guidance.
