Research On Biomass And Carbon Storage Of Forest Vegetation In Jinan City

Combating with the remote sensing image data of Jinan City Landsat in2013and forestresource second inventory data, biomass conversion factor function model was used to estimatethe Jinan City forest vegetation biomass and carbon stock, and on the basis of which analysis abrief of the distribution of Jinan City forest vegetation carbon storage and influence factors,finally, brought the following conclusion:(1)In the major of Jinan City Forest is artificial pure forest, which is mainly distributed insome state-owned forest farm, natural protection area and National Forest Park. In the forest, talltrees is depend on pine forest, Platycladus orientalis and poplar trees, the species is relativelysimple, and vegetation diversity is poor.(2) Jinan city’s forest area increased with a short extent. The City’s land area is100430hm2, in which increased about57hm2than2012; therefore the increased extent ofwoodland area is so short. Among them, the city area of the total forest area is about61033hm2in2013, in which reduced about14hm2than2012; The total area of Zhangqiu City’s forest landis29485hm2in2013,compareing with the last year, it reduced about260hm2; The total area ofPingyin County’s woodland is about8093hm2in2013, in which reduced about36hm2than2012;The total area of Shanghe County’s forest land for508hm2in2013, which increasedapproximately328hm2than in2012; The total area of Jiyang County’s forest land is1311hm2,which increased about39hm2than in2012.(3) Jinan city’s total forest stock volume has increased with a steady growth trend. By theend of2004, Jinan City’s forest total volume is about599.19104m3. Jinan City’s forestvegetation total accumulation amount is about1148.01104m3till the end of2013.Under thecommon efforts of Jinan city government and the forestry sector, Jinan City’s forest vegetationvolume has increased significantly, and which has kept about the average growth rate of7.5%inthese nine years time. (4) The total of Jinan City’s forest vegetation biomass is about631.47104t in2013, themunicipal district’s forest vegetation biomass is about382.13104t, which is accounted60.51%in total vegetation biomass in City Forest, that is the highest than others country. Zhangqiu Cityis the second, whose biomass is about187.58104t, it is accounted29.71%in the city’s totalvegetation biomass. Pingyin County, Jiyang County and Shanghe County’s forest vegetationbiomass were47.84104t,10.23104t and3.69104t, respectively accounted about7.58%,1.62%and0.58%in Jinan City’s total forest vegetation biomass.(5), Jinan City’s forest vegetation carbon storage is about319.11104t in2013, the carbonstorage of municipal district area was about193.54104t, which accounted about60.65%inJinan City was the highest; Zhangqiu City’s forest vegetation carbon storage was about94.71104t, which accounted about29.68%in the total carbon storage; Pingyin County, Jiyang Countyand Shanghe county forest vegetation carbon storage were respectively23.97104t,5.07104tand1.83104t, which accounted about7.51%and1.59%and0.57%in Jinan City’s forestvegetation carbon storage.(6)Jinan City’s forest carbon sequestration value is about20069.02104yuan in2013, themunicipal district area’s forest carbon exchange is about12171.46104yuan, which accounted60.65%in Jinan City’s forest carbon aggregated value is the highest; Zhangqiu City forest carbonsequestration value is about5956.05104yuan, which accounted29.68%in Jinan City’s forestcarbon aggregated value is second; Pingyin County, Jiyang and Shanghe county’s forest carbonaggregated value are respectively1507.57104yuan,31.899104and114.95104yuan,which accounted7.51%,1.59%and0.57%in Jinan City’s forest carbon aggregated value wererelative less than others.
