摘    要:为进一步保护秦岭大熊猫这一独特种群,对秦岭太白、老县城、观音山3个大熊猫保护区栖息地的气候、土壤和水文等生态因子特征进行了深入的调查分析研究。结果表明:秦岭大熊猫栖息地的气候特征、土壤理化性质、水文水质特征在3个保护区的表现均呈现出一定的差异性;在垂直方向上,3个保护区的生态特征随着海拔变化的差异性均比较显著;秦岭气候温和,土壤条件复杂,水质良好,为各种植物的生长提供了优越的自然环境条件,从而进一步为大熊猫种群繁衍和发展提供了有力的保障。

关 键 词:秦岭  大熊猫  栖息地  生态环境  特征

Abstract:The composition and contents of amino acids in three kinds of staple food bamboo(Bashania fargesii,Fargesia qinlingensis and F.dracocephala)for giant panda in Qinling Mountains were determined by the automatic amino acid analyzer and their nutrition was evaluated together.The results showed that samples were hydrolyzed with acid into 17 kinds of amino acids including 8 kinds of essential amino acids.For all samples,Glu content was highest,followed by Asp,Leu,Phe,Val,Ala,Lys,Gly,Pro,Thr,Ile,Arg and Ser,and Cys content was lowest.Except the content of Cys in bamboo leaves was lower than that in stem,the contents of other amino acids in bamboo leaves were significant higher than those in bamboo stem.The proportions of amino acids were higher than the WHO/FAO standard.In this way,these bamboos can provide the protein source with good quality for daily life of giant panda in Qinling Mountain.The results would provide the scientific basis for food resources protection and sustainable development of giant panda in Qinling Mountain.
Keywords:Qinling mountain  Giant panda  Staple food bamboo  Amino acids  Nutrition
