- Abstract: The distribution, yield and sample information data of Pinus massoniana was obtained by document literature and sample investigation. Based on sample data from 12 provinces including 414 sample plots and environment factors in China,the distribution regionalization of P. massoniana was predicted by using Maxent and spatial analysis function of ArcGIS. The results showed that the northernmost distribution of P. massoniana was 33.5 degrees north latitude, and it mainly distributed in the southeast in China. Based on plant age, plant height, yield per plant and other growth index from 414 sample plots, combined vegetation form and other data, the growth regionalization of P. massoniana was carried out by using SPSS and related functions of ArcGIS. The results showed that Fujian, Guizhou and Guangxi had a lager distribution area of P. massoniana, meanwhile, it had a relatively higher yield of fresh pine needles. The relational model between environmental factors and shikimic acid,and procyanidin, and the total lignans was constructed by using SPSS regression analysis method. Then the spatial calculation function of ArcGIS was used tocarry out the quality regionalization of P. massoniana based on the relational model. The results showed that east of Sichuan, Guizhou, Chongqing had a good pine needles quality. Based on the distribution, growth and quality regionalization, the production suitability regionalization of P. massoniana was carried out. The results showed that the optimal planting base region mainly distributed in east of Sichuan, middle and east of Guizhou, and east of Guangxi.
