| 摘 要： | 【目的】对比不同利用方式对草地群落和土壤养分的影响,为制定合理的草地利用方案提供科学依据。【方法】调查确定新源县则克台镇春秋草地不同利用方式,对比分析草地植物群落特征和土壤养分的变化。【结果】放牧利用方式下土壤有机质、碱解氮、有效磷含量高于打草地,其中,划区轮牧和自由放牧草地土壤有机质含量高于分段放牧方式,划区轮牧和分段放牧草地土壤P、K含量高于自由放牧方式。分段放牧和划区轮牧物种数高于自由放牧和打草方式,划区轮牧的地上生物量最高。【结论】放牧利用方式在保持土壤养分、提高草地群落数量特征和生产性能上均高于打草地,划区轮牧是当地适宜的草地生产方式,而分段放牧具有潜在的优势,长期自由放牧则不利于草地可持续发展。

| Abstract: | 【Objective】Comparing with the effects of utilization modes on the grass community characteristics and soil nutrients.To provide a scientific basis for reasonable utilization of grassland.【Method】The four utilization modes of spring-autumn steppe were determined by investigation in Zeketai Town,Xinyuan County,which are mowing grass,normal grazing,sectional grazing and rotational grazing.The objective is to study the effects of utilization modes on the community characteristics and soil nutrients.【Result】 The high soil organic matter,available N and Olsen-P contents can be maintained by grazing rather than mowing.And the organic matter content of normal grazing and rotational grazing is higher than that of sectional grazing place,the contents of available K and Olsen-P of sectional grazing and rotational grazing areas are higher than those of normal grazing.The plant species of sectional grazing and rotational grazing are the highest,and the aboveground biomass of rotational grazing is the highest.【Conclusion】 Considering the community characteristics and soil nutrients,grazing modes are superior to mowing grass in maintaining soil nutrients,which improve community quantity characteristics and productivity.And rotational grazing is appropriate mode of production for that place,and sectional grazing has potential advantage over long-term freedom grazing,which is disadvantageous to grassland sustainable development. |
