| 摘 要： | 本文研究高山草原土不同海拔高度(4287m4、374m和4464m)的土壤养分变化趋势,结果表明:随着海拔的升高,高山草原土土壤有机质、速效养分逐渐减少,土层逐渐变薄;土壤速效养分受海拔高度影响较大,其变化幅度明显高于全量养分。

| Abstract: | The study was conducted the soil nutrient change trends with the different altitude(4 287m,4 374m,and4 464m) in the alpine meadow soil.The results showed the soil organic materials and quick-acting nutrients were decreased and horizon were thinner gradually with the elevation incneased,the quick-acting nutrients were influenenced mainly by elevation.Its change range was higher apparently than total nutrients |
