| Abstract: | This article analyzes the forest structure of greenbelt around Changchun city with the method of sample plot survey.The results show that the forest density of greenbelt around city is 1386 trees/ hm2,which comes up to the standard,the average DBH is 12.5cm,the total biomass is 66794t,the total leaf area of trees is 37 435 900 m2,the LAI is 2.7.The ecological benefit assessment is that the greenbelt around city can remove 17 063.3t CO2,give off 12 410t O2,absorb 8 222.2tdust and assimilate 121.4tSO2. |
