Study On The Water Resources Carrying Capacity Of Liaoning Along Bohai Region For Key Industries

Under country to speed up the regional economic development strategy, driven by along bohai area is developing to become the national macroeconomic strategy important point to areas and become new poles of economic growth. As one of the main distribution area of our country basic and strategic industry, along bohai area occupy the important position in the regional economic pattern.The bohai sea is the only inland seas, ecological condition is superior,rich in biodiversity,its coastal area is important buffer for maintaining the bohai sea ecological functions,in national regional ecological security pattern occupies an important position.However, the shortage of water resources and water environment deterioration and water ecological degradation coexist, constrain harmonious development between regional economic society and the ecological environment.Take water resources carrying capacity as the foundation, scientific adjustment the key industries of the scale, structure and layout, has become a urgently to be solved significant problems of regional of economic and social development.This study based on data collection, model calculation and system integration, and analysis liaoning coastal area around the bohai industrial development phase, the key industry recognition;On the basis of regional water resources and utilization evaluation, recognize the liaoning coastal area around the bohai are facing in the industrial development of the key problems of water; In combination with regional water supply, regional and key industry of water demand, the construction of the carrying capacity of water resources evaluation system dynamics model of liaoning coastal area around the bohai, calculation the carrying capacity of water resources of liaoning coastal area around the bohai,hebei province relevant data for the dynamic model of the system reliability test; Combined with the future development of regional water resources of the new situation, based on the industrial niche theory, according to the water resources carrying capacity of the liaoning coastal area around the bohai,put forward key industry adjustment scheme, and proposed regional industry overall regulation and the security of water resources comprehensive countermeasures.This paper mainly research content:(1) Along the bohai area of liaoning present situation of the development of the industryOn the regional economic contribution to higher, more influence on the ecological environment, regional future planning as determined by the focus of development as recognition standard, system identification the key industry of along bohai area, and evaluate the present situation of the key industry characteristics and development trend.(2) The research present situation of regional water resourcesThe surface and groundwater resource survey along the bohai area of liaoning, clarify water quantity and useable water resources characteristic; Analysis on the evolution of the water quantity trans-regional major issue and the key factor; Identify key industrial development and regional water resources related major problem; Analysis the interaction rule between can useful water resources, the ecological water requirements and the development of economic society key industry layout, identify key industry development strategy on the influence of the water resources.(3) The research present situation of regional water environmentRegional water environment quality overall characteristics and key issues.On regional water environment quality present situation appraisal and retrospective study, summed up in recent years domain of inland surface water environment quality evolution trend, identification of regional key problems of water environment problem.(4) Water resources carrying capacity model building and calculatedTake water resources as the base, study area around the bohai of liaoning water quantity available to trends and regular, main restrict factors of water resources sustainable development;Based on system dynamics model, construct water resources carrying capacity model for liaoning along the bohai region, calculate water resources carrying capacity.(5) Water environment capacity calculationPrediction pollutant discharge total amount of the key industrial along the bohai area of liaoning,prediction of water environment carrying status of key industries, an improved evaluation index system is proposed to calculate the bearing capacity of water environment along Bohai region in Liaoning(6) Water resources optimization allocation policy and technology research of the key industry developmentAccording to the characteristics of shortage of water resources along bohai region, especially in the area where surface water and groundwater are shortage need to solve the problem inter-basin swap water, break administrative region, study cross region and inter-basin water resources comprehensive control policy.Presents the cracking water resources shortage and water pollution problems method of along the bohai area of liaoning, Include Water pollution prevention and control integration technology and Water saving optional integration technology for the key industry.The main innovation points:(1) Organic combinat industry development strategy and resource use strategy, at domestic for the first time, system screening key industry along the bohai area of liaoning, and evaluate the current situation of the development of the key industry;(2) Building system dynamics model of water resources carrying capacity, at domestic for the first time, system calculat water resources carrying capacity of the key industry development along the bohai area of liaoning,and other province data for the dynamic model of the system reliability test.(3) Based on the industrial ecological position theory, according to the water resources carrying capacity of liaoning along bohai area, put forward sustainable development strategies of key industry.The main conclusion:(1) The shortage of water resources restrict the sustainable development of economic society of the liaoning coastal area around the bohaiBased on the research of water resources carrying capacity and water environment carrying capacity in coastal regions, it indicated that key industry scale expanding rapidly and water demand is remarkable,present status of water resources use and utilization efficiency of water unable to support the key industrial development scale and structure.(2) Adjustment of layout and adjustment of structure at the same time to alleviate the shortage of water resourcesWater resources as the development limiting factor,according the ecological principle,limit layout bt water, limit structure by water, limit evelopment by water,limit key industry scale,optimizat key industry structure, adjustment key industry layout,increase regional transferred water measures to alleviate the shortage of water resources.(3) Strengthen the key industrial water pollution control and water saving technology application to improvement of water resources carrying capacityTo develop the water consumption big industries under the condition of shortage of water resources of the liaoning coastal area around the bohai,strengthen the key industrial water pollution control and water saving technology application is important means of improvement of water resources carrying capacity...
