摘要: 对荒漠草原区不同利用方式下的土壤氮、磷元素及植物群落特征进行了研究。结果表明,补播区土壤全磷含量较高,补水补播区土壤全氮含量较高,补水补播区土壤氮磷比最高,禁牧区土壤氮磷比最低;补水补播区植被群落的高度、盖度和密度均要高于其他植被群落区,其中禁牧区最低,由此可以看出,土壤的氮磷比较大程度上影响了植被的群落特征。

Abstract: In the present study, the distribution of nitrogen (N) and phosphorus (P) and characteristics of plant community in the soils with different using ways in desert grassland were investigated. Higher soil total P content and soil total N content was observed in re-seeding area and re-watering and re-seeding area, respectively; the highest and lowest soil N/P ratio was found in re-watering and re-seeding area and grazing-prohibited area, respectively; the height, coverage and density of plant community in re-watering and re-seeding area was higher than that in the other areas, and the lowest value was observed in grazing- prohibited area. The combined data suggest that the soil N/P ratio greatly influences the characteristics of plant community.
