摘要:
为探究蒙古冰草种群动态及叶功能性状在不同群落生境的变化,以宁夏盐池县荒漠草原蒙古冰草+草木樨状黄芪(MC)、蒙古冰草+老瓜头(ML)、蒙古冰草+牛枝子(MN)3种不同群落生境为研究对象,按丛径将蒙古冰草个体划分为Ⅰ级株丛(0~2.0 cm)、Ⅱ级株丛(2.1~4.0 cm)、Ⅲ级株丛(4.1~6.0 cm)、Ⅳ级株丛(6.1~8.0 cm)、Ⅴ级株丛(8.1~10.0 cm)和Ⅵ级株丛(>10.0 cm),研究了不同群落生境蒙古冰草种群的株丛结构和叶功能性状。结果表明:在蒙古冰草+草木樨状黄芪和蒙古冰草+牛枝子群落生境中,Ⅰ、Ⅱ级株丛较多,株丛密度较大,在蒙古冰草+老瓜头群落生境中,以Ⅲ、Ⅳ级株丛为主,株丛密度较小。蒙古冰草+草木樨状黄芪和蒙古冰草+老瓜头群落生境中蒙古冰草叶面积和比叶面积分别为4.68 cm2和41.2 cm2·g-1、4.70 cm2和39.2 cm2·g-1,显著高于蒙古冰草+牛枝子群落生境的3.38 cm2和27.7 cm2·g-1。蒙古冰草株丛结构主要受土壤全钾的影响,而土壤水分、有机碳、全氮和全磷是影响叶功能性状的主要因子。由此,可通过改变种群数量特征和叶功能性状以适应自然生境的变化。
