The Features And Management X Of Forestry Carbon Sinks

Global climate change is triggering more people’s attention,and the increasing concentrations of greenhouse gases such as carbon dioxide,which is important cause of global climate change.To cope with climate change,energy-saving and emission reduction has become the focus of attention.Forestry carbon sinks are an important measure to increase carbon sinks,reduce emissions costs and economically in the future.The study on the characteristics and management model of forestry carbon sinks can make the role of our forest in coping with climate change and global warming further improved in the future.This paper based on the MODIS land use type and NPP data in Xinjiang of 2001～2013,and analysis the temporal variation characteristics of carbon sinks in Xinjiang and the influencing factors of forestry carbon sinks in 2001-2013 years,the results are as follows:(1)Between 2001 and 2013,the range of the average value of NPP in Xinjiang is 18.51～23.60 g/m~2,the range of the average value of NEP in Xinjiang is 4.56～21.84g/m~2,the range of the average value of NPP in Xinjiang forest is 38.58～46.74 g/m~2,the range of the average value of NEP in Xinjiang forest is 38.58～46.74 g/m~2,and there is no apparent annual variation trend,and the carbon sink capacity in Xinjiang is low.(2)Xinjiang carbon sinks in the northwest high,the southeast low trend,in the more abundant water mountain and grassland,agricultural land area,carbon sink capacity,but in the desert-dominated basin areas,carbon sink capacity is weaker.(3)The effects of annual temperature,precipitation and land use type on the total vegetation carbon sinks in Xinjiang are small,and there is obvious positive correlation between Xinjiang forestry land area change and the vegetation carbon sink in Xinjiang.(4)Using GIS to construct forestry carbon sink management model,based on multivariate data,complete the characteristics analyzing of forestry carbon sinks,analyzing the influencing factors of forestry carbon sink and the data management of forestry carbon sink and the data management of foresty carbon sinks and their visualization.
