| 摘 要： | 以克鲁伦河下游地区典型草原为研究对象,以传统游牧作为对照,研究探讨了围栏放牧草场利用方式下土壤养分性状变化规律,其研究结果如下:在冬营盘和夏营盘2个营地,土壤有机质、全氮、全磷和全钾含量均表现为游牧放牧区>轮牧放牧区>打草场,且冬营盘大于夏营盘;土壤有机质、全氮和全磷含量在冬营盘0～10 cm土层上游牧区、轮牧区和打草场之间均有显著差异;土壤全钾含量分布状况与其他养分有所不同。

| Abstract: | Taking the typical steppe in the downstream region of Kelulun River as research object and the traditional nomadism as the control, the changing law of soil nutrient character with intensive grazing has been studied. The results show that in winter quarter and summer quarter, the soil organic mater, total nitrogen, total phosphorus and total potassium is nomadic area 〉 rotational grazing area 〉 clipping pasture, and winter quarter is bigger than summet quarter. In winter quarter, there is among nomadic area, rotational grazing tassium is different with other nutrient. obvious difference of soil organic matter, area and clipping area at 0 - 10 cm soil total nitrogen and total phosphorus layer, the distribution of total po v v tassium is different with other nutrient. |
