【正文】 uge effect in maintaining global carbon balance and mitigating global warming. Forest biomass is the base of evaluating carbon cycling contribution, so studying its regularity of distribution and dynamic change has a significant meaning for us to understand global carbon balance. Jingouling forest farm is located in Northeast China which ranks among top ones of the list of Chinese carbon density storage areas. The change of forest biomass carbon in this place brings many aspects of ecosystem benefits and needs a deeper study. The inventory data of 1987,1997 and 2007 , bined with forest biomass models and GIS was used to analyze the biomass of the temporal and spatial change in Jingouling farm. Finally the biomass temporal and spatial system was developed with GIS secondary biomass storage in Jingouling forest farm of 1987,1997,2007 are respectively , density are respectively t/ hm2, t/ hm2, t/ ratio of mixed broadleafconifer forest, conifer mixed forest, broadleaf mixed forest, Larch forest , other forest types is 5:2:1:1: the time
