Abstract: This paper deals with study the spatial variation characteristics of soil fertility index (index as follows) in different Phyllostachys edulis (Moso bamboo) stands by means of collecting soils sampling in July at fixed monitoring station in the hilly of forest region at Jian-shan mountainous area,Fuyang county,Zhejiang province,In the meantime the mixed coniferous with broadleaf stands (Pinus massoniana+Liquidambar formosana evergreen broadleaved forest) and" aiphyllium forest (Cinnamomum camphora+Castanopsis sclerophylla) were sellected as comparison. The subjection values and index were calculated for evaluating soil fertility condition in term of fuzzy mathematics principles. Resuhs showed that the index of layer I (0--10 cm) is larger than that in layer I1 (10--30 cm) or layer Ⅲ (30--50 cm)among various stands in general, The index of layer I of mixed Moso bamboo with Schima superba stands was larger than that of pure Moso bamboo stands. The index of layer Ⅰ in reclamation pure Moso bamboo stands was lower than that mixed coniferous with broadleaf stands or aiphyllium stands respectively, whereas the index of layer Ⅱ or layer Ⅲ was larger than that in the other stands. The index above three layers was the lowest in no reclamation Moso bamboo stands. While the index in stands mixed Moso bamboo with Schima superba was similar to that mixed coniferous with broadleaf stands above three layers.
