Economic value of vegetation carbon fixation and oxygen release in Loess Plateau of North Shaanxi Province under land-use and land-cover change;

Application of CITYGREEN model in air purification,carbon fixation and oxygen release by greenbelt system of Shenzhen City

On the base of the research of the biomass,according to the relationship between organic compounds and carbon fixation and oxygen release photosynthesis,preliminary study was carried out on the total effects of carbon fixation and oxygen release con.

Ten kinds of familiar plants in Nanyang City,Henan Province,are studied;their quantity of transpiration and cooling in summer and their quantity of oxygen releasing and carbon fixation of per unit leafy area are measured and calculated.

Under the different indoor environment, choose the best plant in the function of nitrogen fixation and oxygen release,transpired water release, absorbed caloric, bacteriostatic action .
