| Abstract: | By adopting the Typical Relation Analysis on the forest growth and the soil factors, the seven factors which indicate the forest soil fertility were discoursed. and the comprehensive class evaluation method of forest soil fertilty is advanced. the forest soil fertility evaluation should begin with the soil physical properties. Seven fertility factors are divided into two classes, the one includes the soil layer depth, soil volume weight, organic matter content, stone content, the other includes the alkaline nitrogen, quick-acting phosphatia. quick-acting potassium. Based on these, twenty one soil groups of eastern Sichuan were evaluated. |
