The Analysis Of Biomass And Ecological Benefit Of Public Welfare Forest In Huzhou

The forest has many kinds of ecological functions,it is the main body of the terrestrial ecosystem,the forest plays a very important role in the ecosystem,and the ecological benefits of forest is more and more recognized by the public.In this paper,the ecological public welfare forest in Huzhou is taken as the research object,and the two element compatible biomass model of Forstat2.0 package is used to analyze the data?After calculation:Huzhou's public welfare forest biomass was 5 million 834 thousand and 600 t of 2008 year,compared with the previous year,Among them,shrub biomass was 37 thousand and 800 t,of total biomass;Chinese fir forest biomass of 127 thousand and 700 t,;mixed bamboo biomass is 144 thousand and 200 t;needle broad-leaved mixed forest biomass of 747 thousand and 700 t,;forest biomass of 1 million 213 thousand and 500 t,;the bamboo biomass is 1 million 352 thousand and 800 t,;biomass of broadleaf forest was 2 million 210 thousand and 700 t,.The economic benefit of Huzhou public welfare forest was 3 billion 737 million 840 thousand yuan in 2008.The volume of water is 706 million 530 thousand T,the social value is 1 billion 266 million 600 thousand yuan;the amount of O2 is 618 thousand and 793 T,the social value is 680 million 670 thousand yuan;the absorption amount of CO2 was 850 thousand and 972 T,the social value is 1 billion 21 million 170 thousand yuan,to maintain the soil or reducing the soil erosion amount was 2 million 564 thousand and 691 T;nutrient replenishment of soil nitrogen 2 thousand and 611 T,657 t pure pure phosphorus,potassium 53 thousand and 308 t.The annual storage energy of 103.5826 Joule trillion produced social value is 246 million 620 thousand yuan;the forest control flood and drought of the social value of 90 million 420 thousand yuan,the social value of forest recreation is 310 million 670 thousand yuan.Significant ecological benefits..The research results provide the basis for the accurate evaluation of the ecological benefits of forest,and provide the basis for the protection of local ecological forest,the adjustment of forest and ecological compensation.
