Abstract:: Taking six types of typical Pinus massoniana in Guizhou as the research objects, we nvestigated the plant species. The communities are named Pinus massoniana+Cunninghamia lanceolata—Castanea seguinii—Rubus buergeri(Ⅰ), Pinus massoniana+Quercus fabri—Castanea seguinii+Quercus fabri—Rubus buergeri+Pteridium aquilinum(Ⅱ), Pinus massoniana +Populus adenopoda—Lindera glauca+Quercus fabri—Miscanthus sinensis(Ⅲ), Pinus massoniana+Liquidambar formosana—Castanea seguinii—Hypolepis pallida+Rubus fockeanus(Ⅳ), Pinus massoniana—Quercus fabri)—Arthraxon hispidus+Macrothelypteris oligophlebia(Ⅴ), Pinus massoniana—Quercus fabri+Rubus leucanthus—Miscanthus sinensis+Ficus tikoua(Ⅵ). The plant diversity and soil physicochemical properties under different communities were compared, and the relationship between the two are explored. The results showed that a total of 120 species of vascular plants, belonging to 62 families and 99 genera, were recorded; the plant diversity indices of different communities had obvious differences, and decreased in the order: Ⅳ>Ⅲ>Ⅱ>Ⅰ>Ⅵ>Ⅴ; in addition, the plant diversity indices in each group were also different between levels; the soil bulk density, water content, pH, total nitrogen, available nitrogen, total phosphorus, available phosphorus, available potassium, organic matter, etc. of different Pinus massoniana clusters were significantly different(p<0.05); The soil nutrients of cluster Ⅳ were significantly higher than those of the other cluster types. The results of CCA analysis showed that soil conductivity, altitude, canopy closure, bulk density, available phosphorus may be important environmental factors affecting the distribution of plant species in the Pinus massoniana stand(p<0.05).
