摘要
[目的]了解流动沙丘人工栽植塔郎造林的治理沙地效果.[方法]采用时空替代的方法,研究赤峰市采取塔郎造林治理沙地后1～ 10a草本植物的多样性变化动态.[结果]随着年限增加,植物种类增加;Shannon-Wiener、Simpson和Margalef指数均增加,Pielou指数逐渐降低;与造林当年相比,群落相似性系数逐年降低,植被恢复明显;造林后3 ～7a植物群落为稳定群落;植物群落优势种主要以塔郎、沙蓬、虫实、狗尾草和沙蒿为中心发生变化;造林10a后植物多样性指数逆转,应继续加强灌木林经营管理.[结论]研究结果为沙地治理模式的选择提供了理论依据.
Abstract
[Objective] To research the sand-control effects of planted Hedysarum leave afforestation in moving dune.[Method] By using the method of spatial and temporal replacement,dynamic change of herbaceous plant diversity was researched after 1-10 years of Hedysarum leave afforestation in moving dune in Shifeng City.[Result] Plant types enhanced as the years increased.Shannon-Wiener,Simpson and Margalef indexes all enhanced,but Pielou index reduced.Compared with afforestation in the current year,population similarity coefficient reduced gradually ; and vegetation recovery was significant.Plant community became stable in 3-7 years after afforestation.Dominant species of plant community changed with the center of Hedysarum leave,Agriophyllum squarrosum,Corispermum declinatum,Setaria viridis and Artemisia desertorum.The index of plant diversity reversed 10 years after planting.Thus,the management for shrubs should be further strengthened.[Conclusion] This research provides theoretical foundation for the selection of sand control mode.
