中文摘要：

该实验通过对中国科学院海北高寒草句生态系统实验站地区，连续放牧、间隔放牧和未放牧三种放牧类型的草地土壤中全氮含量的测定，初步得出土壤全氮含量不仅受土壤类型、气候等的影响，更受放牧类型的影响。结果表明，间隔放牧类型的土壤全氮含量最高，为土壤肥力评价及合理放牧等提供了依据。

英文摘要：

In this article , total nitrogen content in the three types of soil ： continuous grazing soil, interval graz- ing soil and no grazing soil were measured, through studied the place of the Chinese Academy of Sciences in Alpine Meadow. The result indicated that total nitrogen content was related to the tape of grazing, and found that interval grazing soil was the best tape. It is good for soil fertility evaluation and reasonable grazing.
