Courtyard Ecological Economic Development Pattern And Benefit Evaluation In Three River Source Area

The three river source area is located in hinterland of Tibat Plateau,is an important areathat our country’s and southeast Asia’s water conservation,to safeguard China’s economicdevelopment has the important ecological status in the central east area.Since the three riversource nature reserve policy implementation and YuShu earthquake in2010,a number of coreresidents and earthquake victims moved out their long-term resident land and from thetraditional nomadic scattered into a settlement,so they changed the production and lifestyle.How to further optimise economoc model in immmigrants area and make immigrantscan move out,staying and good development.This study through plenty of field investigationand combined with the regional natural resource conditions, social economic conditions andcharacteristics of religious culture present that build plateau solar aided biogas courtyardecological economic model and community solar aided biogas circular economy model basedon rural household.The enphasis of this paper is to region defined and regionalresource,economy and social development, three river source courtyard ecological economicdevelopment of renewable resources potential evaluation,three river source courtyardecological economic model design and solar aided biogas digestion device design,analyze thebenefit of what three river source courtyard ecological economic model design,thecountermeasures to develop three river source courtyard ecological economic model and soon.The main results are as follows:1.Region defined and regional resource,economy and social developmentAccording to three rivers resource natural protecting areas planning scheme and the planfor post-earthquake recovery and reconstruction of Yushu area,defines appropriate rangewhich involves courtyard ecological economic model.Analyze the nature resources fordevelopment such as solar radiation, sunshine, temperature, precipitation andpopulation,livestock,the social and economy condition in courtyard ecological economicmodel, reviwewed the three river source the Ecological Migration and post-earthquakerecovery and reconstruction.2.The three rivers source courtyard ecological economic development potential ofrenewable resourcesBy building a model to analyze the source area of courtyard ecological economic modelinvolving solar energy and biomass energy resource potential and put forward the three rivers source ecological migration points have resource advantages and conditions of developmentcourtyard ecological economic model.3.The three rivers source courtyard ecological economic model designAccording to nature and economic condition of the three rivers source,puts forward theconcept of courtyard ecological economic system of three rivers source，analyze constraints ofplateau courtyard ecological economic system and constructing principle of courtyardecological economic model,on this basis,Designed two courtyards ecological economic modelbased on the household level and community level,proposed key devices and technologies ofthe Three Rivers Source Ecological Economic courtyard for the model.4.Design of a solar aided biogas digestion deviceAimed at the key technology and system structure of plateau courtyard ecologicaleconomic model is designed a design plan of solar aided biogas digestion device.According tothe heat balance equation,chose configuration parameters of solar collectors, inlet and outletpipelines, electric heating system, control system and circulatory system.On this basis,aimedat different user demands is designed6m3-2000m3series digesters as the core deviceparameters.5.Benefit analysis of the three river source courtyard ecological economic modelBy building model to analyze input costs, economic, ecological and social benefits oftwo kinds of courtyard eco-economic model of household and community levels.6.Development strategies of the three river source courtyard ecological economic modelFrom a social level, technical level and the policy level proposed science and technologyneeds, policy support measures of the three river source nature reserve area ecologicalmigrationapp:addword:migration points courtyard economic model development.In summary，since the three river source nature reserve policy implementation and theplan for post-earthquake recovery and reconstruction of Yushu area,a number of coreresidents and earthquake victims from the traditional nomadic scattered into a settlement.Thethree river source area is located in hinterland of Tibat Plateau,so higher elevations,lowertemperatures,but biomass energy is abundant,solar energy resource is sufficient.On thisbasis,build plateau solar aided biogas courtyard ecological economic model and communitysolar aided biogas circular economy model based on rural household.The research results mayprovide technical support and theoretical guidance for understanding the building the threerivers source courtyard ecological economic model.
