Ecological value of swamp in Sanjiang plain

Sanjiang Plain is rich in swamp resources, which plays a significant role in regulating the regional climate, playing an important role as a "biological reservoir" and playing an important role in fishery and reed industry. The rich peat resources in this area can also be developed in large quantities as organic fertilizer. Sanjiang plain swamp is developed on the low plain and has unique characteristics in China. As far as hydrological function is concerned, the swamp on the floodplain can reduce the flood peak, homogenize the flood process, and even have the regulation function comparable to that of forest. In regulating climate, swamp can make the temperature in its vast neighborhood rise relatively. Marshes also affect the gas composition in the atmosphere. The marsh vegetation on the earth releases 1.6× 10.8 tons of oxygen into the atmosphere every year, which can also purify the environment. Marsh can effectively increase the surface roughness and prevent the continued development of erosion hazards.
