| Due to the special location of Tibet plateau,there were various wetlands and the eco-system of which had great importance to the whole world.There are rich plateau wetlands ecosystems in Tibet which is endemic to China.Through spotting observation and literature analysis,the research systematically studied the structure,distribution and characteristic of Tibet wetland eco-system.The wetlands in Tibet plateau have such characteristics as various wetlands types, wide distribution but uneven and abundant biodiversity and frangibility,and so on.By adopting reflection engineering method,the market value method and carbon tax revenue method,the estimated total value of the wetland ecosystem service funcation was 6 207.83×108 yuan/year.According to value quantity,the service order was decreasing pollutants>regulating atmosphere component>controling and storing flood>material production>regulating climate>scientific and cultural research and biology habitats>water storage.Among which,maximum was decreasing pollutants 2 080.15×108 yuan/year,and minimum was water storage 25.12×108 yuan/year. |
