摘要: 草地退化会呈现出地上群落与土壤的同步退化,相对于地上植被的退化,土壤退化呈现一定的滞后性,为分析藏北高寒草地退化过程中的群落地上生物量与土壤养分关系,选取那曲地区不同退化程度高寒草地,对土壤养分和地上生物量进行研究。结果表明,随着退化程度的加剧,藏北地区退化草地群落地上生物量和土壤养分(除全钾外)总体上表现为降低趋势,而且步调基本一致。土壤全氮、全钾含量与土壤有机质呈显著正相关(P<0.05),土壤pH与有机质含量呈显著负相关(P<0.05)。草地地上生物量与土壤有机质含量呈显著正相关(P<0.05),与全氮、全磷、全钾含量的相关性不显著(P>0.05)。

Abstract: Grassland degradation had characteristic of vegetation and soil degradation synchronization. In order to study the relationships between community biomass and soil nutrient during degradation processes in the northern Tibet grassland, alpine grassland in Nagqu, northern Tibet with different degraded degrees were selected to study the variations of soil nutrients and above ground biomass. The results showed that with increasing of grassland degradation, aboveground biomass and soil organic matter significantly decreased. Total nitrogen, total phosphorus and total potassium had significant positive correlation with soil organic matter (P<0.05) whereas soil pH had significant negative correlation with soil organic matter content (P<0.05). Aboveground biomass had significant positive correlation with soil organic matter content (P<0.05) but had no correlation with total nitrogen, total phosphorus, total potassium and pH (P>0.05).
