平朔煤矿复垦区不同人工林草本层植物群落特征
Characteristics of Plant Communities in Different Herbaceous Layers of Plantation Forests in Pingshuo Coal Mine Reclamation Area
摘要
Abstract
Changes in the composition and diversity of plant communities during vegetation restoration in reclaimed areas can en-hance our understanding on the evolutionary processes and patterns of plant communities.Four planted forests,Populus simonii,Pinus tabuliformis,Ulmus pumila and Robinia pseudoacacia in a typical coal mine reclamation area in Pingshuo,Shanxi,were se-lected to analyze the composition and species diversity of the understory herbaceous community and to investigate the influence of soil and stand on the herbaceous layer of the plant community.The aim of the present study was to provide basis information for spe-cies selection in the later stage of mining area reclamation.The results showed that:(1)there were 25 families,49 genera and 59 spe-cies of understory herbaceous plants,among which the A.Bercht has the most species,followed by the F.Lindl and P.Barnhart,and the life type is mainly perennial herbs.The dominant species of plants are mainly woodland P.nemoralis,M.sativa and S.chamae-jasme.(2)The herbaceous diversity of the P.tabuliformis showed a trend of increasing and then decreasing during vegetation recov-ering,while the opposite trend was observed in the U.pumila,and no obvious trends were observed in the P.simonii and R.pseudo-acacia communities.(3)Soil organic matter and total nitrogen increased significantly(P<0.05),soil bulk density decreased signifi-cantly(P<0.05),and total phosphorus increased significantly(P>0.05),except for R.pseudoacacia,while soil water content did not change significantly(P>0.05).(4)Soil physical and chemical properties and highly significant effects on herbaceous communi-ty composition(P<0.01).The study reveals the successional characteristics of herbaceous communities under different plantation forests in the Pingshuo coal mining reclamation area,which can provide a scientific basis for the ecological restoration in this area.关键词
