以景谷县思茅松天然乔木林为研究对象，以2006年森林资源二类调查数据和 DEM为信息源，在前期实测120株思茅松单木生物量建立思茅松单木生物量估测模型基础上，对研究区思茅松天然林乔木生物量的空间分异特征进行分析。研究结果表明：思茅松单木生物量模型以幂函数模型精度最高，决定系数 R2＝0.9528，估测精度 p ＝85.4％，均方根误差 RMSE ＝14.81kg，可用来进行思茅松天然林生物量估测；在空间分异上，研究区思茅松天然林乔木生物量集中分布于海拔1000～2000 m，在海拔1500～2000 m 时生物量密度最大，为73.33 t／hm2；坡度对生物量影响主要集中在陡坡、缓坡和斜坡上，其中，在急坡上生物量密度达到最大，为76.17 t／hm2；生物量在各个坡向上的分布相对较均匀，生物量密度在阴坡上最大，为74.13 t／hm2，在阳坡上最小，为70.42 t／hm2。

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 con-centrated 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.
