摘要：为探讨不同放牧方式下的草地植被组成变化,研究放牧方式对草地植物群落数量特征及生物多样性特征的影响,以浑善达克沙地东缘克什克腾旗为研究区域,通过对3种放牧方式的比较研究,结果表明:不同放牧方式在一定程度上改变了植被种群结构。自由放牧的优势种为羊草、落草,季节性放牧的优势种为羊草、碱蒿,划区轮牧的优势种为羊草和沙米;总体来说,划区轮牧下的植物种数、盖度、高度、生物量及多样性指数均高于季节性放牧和自由放牧。说明适宜的放牧方式可提高草地生态系统的稳定性和生产潜力。
In order to explore the change of grassland vegetation composition with different grazing patterns,research the influence of grazing patterns on the quantitative characteristics of grassland plant community and biodiversity characteristics,taking Keshiketeng Banner in the east edge of Hunshandake Sandy Land as the study area,the results show that the different grazing patterns have changed the population structure of vegetation in a certain extent. The dominant species of free grazing are Leymus chinensis and Koeleria cristata,the dominant species of seasonal grazing are Leymus chinensis and Artemisia anethifolia,the dominant species of rotational grazing are Leymus chinensis and Agriophyllum pungens. In general,plant species,coverage,height,biomass and diversity index under the rotational grazing are higher than the seasonal grazing and free grazing. The adaptive grazing pattern can improve the stability and production potential of grassland ecosystem.
