Ecosyetem Services Evaluation Of Momoge Nature Reserve Wetland

Ecosystem is sustaining system of life on the earth,which is based on economy society to live and develop by human,but wetland is one of the three important ecosystems(forest,sea and wetland)and it is especial on the earth .This paper comprehensively assessed service value of Momoge Natural Reserve Wetland Ecosystem.The main serve functions of Momoge Wetland ecosystem includes water storage ,flood regulation,climate regulation,water clearing,purification,CO2 fixation and O2 release,controlling corrosion and soil protection ,life-form habitats ,amusement and scientific research .Now,Momoge Natural Reserve has lots of environmental problems ,such as short of water , wetland ecosystem degenerating;no supervision as clear as a bell , agriculture and breaking into ;area of tour badly pollutant;living and production of industry and agriculture pollutant ;oil extraction pollution . This thesis quantitatively estimated the direct and indirect functional value of wetland ecosystem by different methods(such as market value method ,shadow engineering method ,carbon tax approach and reforestation cost approach).The article computed the direct and indirect serve function value of Momoge wetland ecosystem ,totally ten kinds (direct value including fish,plant,water supply and sluice ,scientific research and amusement ,indirect value including flood regulation,species diversity,climate regulation,soil protection and purification ).The total of serve function value of Momoge wetland ecosystem is 5.15×10~4 millions .Because of indetermination of un-value in use ,the thesis couldn't quantitatively assess it .The result indicated :purification and flood regulation is the magistral service of Momoge wetland ecosystem ,these two is 72.87 percent of serve function value of Momoge wetland ecosystem ,thereinto ,the value of purification is 20331.14 millions yuan per annum that is 39.47 percent of the gross ,the value of flood regulation is 17200 millions yuan per annum that is 33.40 percent of the gross ,the service value of Monoge wetland is 64.9×10~4 yuan per proportion and annum ,it is much more than the one of countrywide ecosystem whose is 0.54×10~4 yuan .Form that we can see the value of wetland ecosystem is very important ,the result matches with the research Costanza .The direct value of Momoge wetland ecosystem is 8378.3818millions,16.27percent of the gross ,indirect value is 43126.3933 millions,83.73percent of the gross ,it indicated that the indirect value is much more than the direct one .This result could apply into decision-making ,supply scientific basis on the building ecosystem ,protecting and managing resource.
