A Study On Fargesia Qinlingensis Population Age Structure And Biomass In Taibai Mountain Habitat For Giant Pandas

Taibai Mountains is the primary one of the China’s first level rare animal under legalprotection, giant pandas live mostly in Qinling Mountains. In the area, fargesia qinlingensishas been the main food resource for giant pandas. Thus rational development and sustainableutilization of the fargesia qinlingensis has a great effect on the pandas’ survival andreproduction. This study carries the aim of providing theoretical proofs for biotope selectionof the panda’s artificial breeding, so that the pandas, their habitat and their food resources canbe better protected. Also quantificational statistics analysis has been included on fargesiaqinlingensis population from8different spots in Taibai Mountain protection area, in terms ofthe biomass of the functional components like leaf component, main stem component andsubterranean stem component, and their age structure. The research shows as follows:(1) Every fargesia qinlingensis of the area is of growing age structure as their mainstem number decreases from lower age class to higher age class;(2) Age of the fargesia qinlingensis can be preliminarily inferred, because the fargesiaqinlingensis individual Rhizome diameters and lengths turn out to be growing, reaching theirmaximum figures at11age-class; as the age class of the fargesia qinlingensis populationincreases, their primary lateral branches drops in numbers and average length;(3) Overground biomass of the fargesia qinlingensis exceeds their underground biomasswith high percentages; overground biomassive order falls from their main stem to primarylateral branch to leaf, while underground biomassive order from their traverse stem to root tobud; Under different habitat conditions and different elevation, fargesia qinlingensis presentsgreat difference in terms of its population components biomass and total biomass per unitarea.The fargesia qinlingensis of growing age structure is more aligned with needs ofsurvival and reproduction of pandas inTaibai mountain area. The primary edible parts offargesia qinlingensis to pandas is main stem and primary lateral branch respectively insequence. The overground biomassive order of fargesia qinlingensis in Taibai mountain areais more aligned with pandas’ eating habits. It also indicates that pandas have made a choicein distribution of components biomass of fargesia qinlingensis when developing their eatinghabits. In addition, fargesia qinlingensis allots high proportion of biomass to their traverse stems, which plays a vital role in maintaining its population growth and renewal and reducingshoot mortality risks. The above all factors prove that Taibai Mountain Area is one of the besthabitats for ailuropoda melanoleuca qinlingensis.The effect of environmental factors on growth of individual species and theirfunctional components is quite obvious, in which elevation exert an important effect in somedegree. In birch forest ecological environment at an altitude of about2100meters, thepopulation biomass and total biomass per unit area of the fargesia qinlingensis come inmaximum. This indicates that the birch forest at an altitude of about2100meters is the besthabitat for fargesia qinlingensis and deserves a key protection.
