| 摘 要： | 通过筛选适生植物,为退化盐漠带生态系统恢复与重建提供参考物种,达到提高绿洲生态系统稳定性的目的。在盐漠带植物种群结构组成、物种多样性及生态位宽度方面进行了综合分析。结果表明,猪毛菜,柽柳,盐爪爪,骆驼蓬在植物种群生态特征方面优势明显,在盐渍化环境下适应能力较强;结合生态位宽度综合分析,得出土壤盐分维最大,为0.5832,其次是有机质、全氮、水分,综合值分别为0.4800、0.4379与0.2201。由此得出,骆驼蓬、柽柳、猪毛菜、盐爪爪为优势适生种;盐漠带植物物种多样性不高,主要受到盐分与水分限制。

| Abstract: | Natural plant was studied in salinization-desert zone in Manas river valley. The dominant species in salinization areas can improve ecological stability and maintain high productivity in the farm; Through the analysis of plant species composition, community diversity and niche breadth, dominant species were selected and its species diversity were studied; Peganum harmala L., Tamarix hispida, Salsola collina, Kalidium foliatum as dominant species; From the analysis, the niche breadth of soil salinity, organi... |
