Abstract:

In order to improve the urban ecological environment of Daqing marsh nature reserve as soon as possible, and improve the total ecological and environmental quality constantly, the author mainly began with the air-conditioned function of Daqing marsh, according to the principles of environmental economics and ecological economics, to estimate the air conditioning function provided by the marsh scientifically by adopting carbon tax. The results showed that, the value of CO2 fixed by the main vegetation of Daqing marsh was RMB 495 million, and the value of O2 released was RMB 435 million. Except the value RMB 10 million of the greenhouse gases emission loss, the value of the atmosphere regulatory function of this area ecological system was RMB 920 million, and the gas regulatory value was RMB 6862 per hm2. This study indicated that, CO2 in the atmosphere was fixed by the Daqing marsh ecological system when O2 in the atmosphere was increased. It played an irreplaceable role to maintain the dynamic balance of CO2 and O2 in the area atmosphere, slow down the greenhouse effect, and provide the basic conditions for human existence.
