| 摘 要： | 运用Biolog-ECO技术,分析半干旱黄土丘陵区不同生长年限紫花苜蓿（Medicago sativa）地和坡耕地土壤微生物功能多样性。结果表明：①在0～15 cm土层,平均吸光值总体变化趋势为生长旺盛苜蓿地显著优于极度退化苜蓿地、退化苜蓿地和坡耕地,坡耕地最差;在15～30 cm土层,平均吸光值总体变化趋势为极度退化...

| Abstract: | In this paper,the Biolog-ECO plates(Biolog,USA) were used to study the functional diversity of edaphon communities in Medicago sativa fields of different growth years in a semiarid loess hilly region.The results are as follows:(1) In the 0-15 cm soil layer,the average absorbance value in vigorous Medicago sativa fields was significantly higher than that in the severely degenerated Medicago sativa fields,degenerated Medicago sativa fields and slope farmland,especially the slope farmland;in the 15-30 cm soil ... |
