Abstract:

为研究蜥蜴(Phrynocephalusfrontalis)活动对内蒙古典型草原群落多样性、地上生物量、群落结构、生活型组成以及优势种生物量的影响,于2012年6月和8月在内蒙古毛登牧场围封草场内布设有蜥蜴样地和对照样地,进行样方调查和生物量取样.结果表明与对照样地相比,蜥蜴样地6月的Shannon-Wiener指数和均匀度显著降低,8月Shannon-Wiener指数、均匀度和物种丰富度均显著低于对照样地;蜥蜴样地的群落生物量在6月和8月分别比对照样地高68.85和111g·m-2;在功能群水平,蜥蜴样地一年生植物和多年生禾草的生物量比例比对照样地增加了19.1%和11.0%,而多年生杂类草生物量比例降低了19.8%;在物种水平,蜥蜴样地羊草(Leymuschinensis)生物量的比例在生长季节初期达到了75.0%.可见在内蒙古典型草原,蜥蜴干扰可使一年生植物和多年生禾草的生物量比例增加,而使多年生杂类草的物种数和生物量比例显著降低;蜥蜴干扰显著促进了羊草的生长;同时会降低群落的物种多样性,提高地上生物量.
