It has great significance to know the relationship between forest characteristics and spatialstructure with carbon sinks.In Coniferous-Broadleaved Forest in Mount Tianmu,Anatural,anthropogenic and rare standard plot was set. For each sample, it was investigated, estimatedbiomass by biomass method of per plant, and converted to carbon stocks. Using neighborhoodcomparison, mingling, angular scale and other indicators to analyze the spatial structure, which isabout the analysis of carbon storage distribution of different spatial structure, as well as differentlevels of carbon storage in tree height. While the species is divided into five types, carbon storagebetween different species was conducted.Finally,using geostatistical methods to learn the difference incarbon storage distribution,and propose recommendations on forest management.Through the research, we draw the conclusions as following:(1) It has rich species, complex stand in Coniferous-Broadleaved Forest,,it is mixed, moderationand slug growth momentum distribution in the forest.(2) The distribution of carbon stocks is changed on different spatial scales with low-high-low andchanging smaller after some number, and it would have no or be lowest in some carbon storageclass.It changs on different neighborhood comparison, mingling, angular scale with low-high-lowand changing small after some number. in different Height level, within the0-30class, the number ofcarbon stocks on2-3,3-4,4-5,5-6,6-7,7-8,8-9height level than others, where the number of level6-7is highest. Within the30-100range, the changing of carbon stocks is little,and there is no relationshipwith plot size.(3) In five species type, the carbon storage change of â…¡ hardwood, softwood and cedar peakare higher,which the number of â…¡hardwood is more obvious than others, the carbon storage changeofâ… hardwood and pine are relatively low.(4)Carbon stock chart shows a clear difference between the high value and low value area, thereis a lot variability of carbon storage spatial structure,and in the same spot, high value area is notSimilar to low value area,the changing between the high value and low value area is not choppy. italso differs between different spots,and high value areas are distributed on decentralized or regionaldistribution,low value areas are more scattered. In Tianmu Coniferous-Broadleaved Mixed forest, tree species is rich, accumulation of carbonstock is high, it plays an important role to improve atmospheric conditions. species distribution andcomplex spatial structure is good for carbon collection. in order to increase carbon sinks, to maintainthe distribution of forest stand structure and its complexity, we should keep forest closed, strengthenforest protection and management, and make full use of natural productivity of the forest.
