皇甫川流域不同植被类型植物群落特征与土壤抗蚀性关系的研究
Relationship Between Plant Community Characteristics of Different Vegetation Types and Soil Erosion Resistance in Huangfuchuan Basin
摘要
Abstract
To explore the characteristics of plant communities and soil erosion resistance under different vegetation types in the Huangfu Basin,the community characteristics of mosses and herbaceous plants of different vegetation types in the Huangfu Basin were investigated,including 20-year artificial oil pine forest,20-year artificial pine and poplar mixed forest,40-year artificial oil pine forest,40-year artificial poplar forest,artificial caragana shrub forest,degraded grassland and bare land.The soil erosion resistance from 13 indicators was comprehensively evaluated by using principal component analysis.The results showed that the α diversity of mosses was the highest under 40-year artificial oil pine forest;the species richness and evenness of herbaceous plants were the greatest under 40-year artificial poplar forest.The surface roughness,saturated hydraulic conductivity,soil organic matter content,total carbon and total nitrogen content,and bulk density of artificial tree forest,artificial caragana shrub forest and degraded grassland were higher than those of bare land,while the average weight diameter,pH and erodibility K factor were lower than those of bare land;the particle size was mainly concentrated in 10-250 µm;the soil cohesion of artificial tree forests was higher than that of bare land.The principal component analysis indicated that soil total nitrogen,soil total carbon,organic matter,silt content and surface roughness were important indicators for evaluating soil erosion resistance;the comprehensive soil erosion resistance of 40-year artificial oil pine forest was the highest,and that of artificial caragana shrub forest was the lowest.关键词
