| 摘 要： | 对天山中部4种不同郁闭度天然云杉林立地土壤养分进行了分析,结果表明,4种郁闭度之间和不同土层土壤养分含量具有一定的相关性。具体表现为郁闭度较大的云杉林立地土壤养分含量总体高于郁闭度小的云杉林。在土壤剖面上,pH值与土层深度没有显著的相关性,而有机质、全氮、全磷、速效养分等指标则随着土层深度的增加而不断降低,与土层深度呈明显负相关。表层与其余土层养分含量差别较大,土壤养分"表聚"现象明显。

| Abstract: | The soil nutrient of four different canopy density of natural spruce forest in the central Tians- han were analyzed,the results showed that there was a closed relationship between canopy density and soil nutrient content. The soil nutrient content of spruce forest with small canopy density was lower,compared with that of spruce forest with great canopy density. In the soil profile,pH had not significant relationship with soil depth. ;soil nutrient indicator,like organic matter, total nitrogen＇, total phosphorus,available nu- trients, declined with increasing of soil depth,indicating they had a significantly negative relationship with soil depth. The difference in soil nutrient content of different soil layers was significant and many soil nutri- ents concentrated on surface layer. |
