中文摘要	用样带法研究藏北高寒植被地上生物量与土壤环境因子之间的关系,对高寒植被地上生物量和7个土壤指标进行相关性分析和回归分析,结果表明:高寒草原到高寒荒漠植被,群落组成逐渐趋于简单化.土壤环境因子影响高寒植被地上生物量,0~10cm土层的土壤有机碳,有效氮,全磷和速效磷与高寒植被地上生物量极显著正相关(P<0.01);10~20cm土层的土壤总有机碳和全磷与高寒植被地上生物量极显著正相关(P<0.01);20~30cm土层的土壤各环境因子与高寒植被地上生物量的关系均未达到显著水平
英文摘要	Relationships between aboveground biomass and the soil factors in alpine grassland were studied in north Tibet. Correlation and regression analysis was used to study the relationships between aboveground biomass and seven soil factors. The results indicated that community composition gradually tends to simplify from alpine grassland to alpine desert. Organic carbon, available nitrogen, and available phosphorus in soil in the 0~10cm soil layers were positively correlated to aboveground biomass significantly(P<0.01);organic carbon and total phosphorus in soil in the 10~20cm soil layers were positively correlated to aboveground biomass significantly(P<0.01);the relationships between soil factors in the 20~30cm soil layers and aboveground biomass were not significant
