Abstract:

In order to speed up utilization and layout of gardens green waste in Beijing, moreover to reduce the pollution of environment and realize the resource recycling, the experiment was conducted by using 14 kinds of main species in Beijing to estimate the biomass model of trees and shrubs, moreover to estimate the amount of gardens green waste in Beijing suburbs in Jiufeng National Forest Park, West Hill Farm Pass Area, Xigou Village in Sihai Town of Yanqing, Daxing Farm. The results showed that, the amount of gardens green waste in Beijing suburbs was 406.395×104 t, which was distributing Miyun County, Huairou Area, Fangshan District and Yanqing County. According to the calculation tree species, trees produce garden green waste which was the most, economic forest was the second, and open and nursery was the less. Garden green waste which was produced by trees was mainly distributed in Yanqing County, Daxing Area and Huairou Area, the green waste from the trees around the village was mainly distributed in Fangshan District and Shunyi District and the green waste from economic forest was mainly distributed in Miyun County. The factors which influenced the amount of green waste were city garden tending clip rules, forest tending rules and cutting task, natural disasters. Scientific measurement of the amount of green waste was providing theoretical number to construct processing point, which was the starting point of using the green waste.
