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.
