| Abstract: | 【Objective】 To study the correlation between the diversity of herbaceous plants under two forest types in order to provide scientific basis for the reasonable management of soil quality and the scientific protection of species diversity in Picea schrenkiana forest. 【Methods】 Two forest types, Mesophyll- Picea schrenkiana forest and moss- Picea schrenkiana forest, were taken as the research objects, and herbage species diversity of 4 ages was analyzed by diversity index, and the correlation between soil physical and chemical properties and species diversity was studied by multivariate statistical method. 【Results】 There were 93 species of herbaceous plants in 34 families and 77 genera in the study plot. The dominant species of the two forest types were shade tolerant and mesophytic grasses, respectively. The diversity index of stand decreased with the increase of stand age. Understory herbaceous species diversity was mainly affected by soil bulk density, organic matter, total potassium and total nitrogen content, and soil factors could only explain 27.10% of the variation of understory herbaceous vegetation diversity. 【Conclusion】 The soil bulk density, organic matter and total nitrogen content is the main soil factors affecting the Picea schrenkiana forest herb species diversity, but its corresponding small, indicating some unknown factors in the region more forests herbaceous species diversity has a great influence, subject to further plant physiological ecology characteristics and environmental factors such as study together. |
