| 摘 要： | 目的]为了研究扎龙自然保护区羊草种群分蘖株的数量性状。方法]以扎龙羊草种群为研究对象,以年龄结构为切入点,对不同土壤生境条件下羊草分蘖株的数量性状进行了研究。结果]在5~9月的取样中,扎龙保护区4种生境的羊草种群分蘖株平均数量表现为沙土>林间风沙土>草甸土>中度碱土,年龄结构最多由3个龄级组成,其中均以1龄和2龄级分蘖株占绝对优势,3龄级所占比例甚小,呈增长型年龄结构;不同生境分蘖株的生物量也表现为沙土>林间风沙土>草甸土>中度碱土,年龄组成均以1龄和2龄级分蘖株对种群物质生产的贡献大,3龄级所占比重很小,也呈增长型年龄结构。结论]该研究为湿地的管理、开发利用提供了理论基础和理论指导。

| Abstract: | Objective] The aim of the research is to study quantity characteristic of Leymus chinensis population tillering plants in Zhalong natural reserve.Method] With Leymus chinensis population as research object and the age structure as cut-in point,the quantity characteristics of Leymus chinensis tillering plants growing in different soil habitat conditions were studied.Result] During the sampling course(from May to September),the average quantity exhibitions of Leymus chinensis population tillering plants growing in 4 kinds of soil habitats in Zhalong natural reserve were as follow: sand soil > wind-sand soil in woods > meadow soil > moderate alkali soil.The age structure was consisted of 3 age classes at most,and the tillering plants of 1 age class and 2 age class had absolute advantage and 3 age class took very little proportion,showing the growing age structure.The biomass of tillering plants growing in different soil habitats were also as follow: sand soil > wind-sand soil in woods > meadow soil > moderate alkali soil.In age structure the tillering plants of 1 age class and 2 age class had more contribution to the population production and 3 age class took very little proportion,also showing the growing age structure.Conclusion] The study supplied theoretical basis and guidance for management,development and utilization of marsh. |
