典型草原不同放牧方式植物群落多样性研究
Study on Communities Diversity of Different Grazing in Typical Steppe
摘要
Abstract
The experiments of comparing four season rotational grazing, two season rotational grazing and continuous grazing were conducted on typical steppe in East Wuzhumuqin count of Inner Mongolia. Study the communities structure and diversity of different grazing in typical steppe. We mainly discuss characteristics of plant diversity under different grazing. It provide reference and theoretical basis for ecological restoration and sustainable use. The results showed as fol-low: the Stipa krylovii important value of four season rotational grazing was the largest, settled grazing annuals was in-creased . In the two-year except for the evenness index other indexes had increased, plants simpson of four and two season rotational grazing was lower than the settlement.Shannon-wiener and Margalef correlation coefficient was 0.891 .Shannon-wiener and Simpson index correlation coefficient was 0.899. Three diversity index and Pielou index were a negative corre-lation. The Morisita-Horn similarity coefficient in the two year were increased,The Morisita-Hom similarity coefficient in TG and SG were the highest.The Morisita-Hom similarity coefficient in FG and SG were the lowest.关键词
