Abstract

Abstract: The forest resource inventory data for management in Jinggu county in 2006 were used as the information source.The biomass and related factors of standard simao pine were used to build a model and the biomass of simao pine stand in Jinggu county was analyzed.The results show that the power function model has the highest precision,R²=0.9528,p=85.4％,RMSE=14.81(kg),this model can be used to estimate the simao natural forest biomass.Simao pine trees in the study area of natural forest biomass concentrated at the altitude of 1000~2000m,and the biomass density is the highest at the altitude of 1500~2000m with 73.33t/hm²;Simao pine trees natural forest biomass mainly concentrated on steep slopes,gentle slopes and slopes,in acute slope biomass density reaches a maximum of 76.17 t/hm².Distribution of biomass in each upward slope is relatively uniform,biomass density on the shady slopes is the highest with 74.13 t/hm²,on sunny slope it’s the lowest with 70.42 t/hm².

Key words: simao pine, biomass, altitude, slope, aspect
