| 摘 要： | 结合土壤磷素形态及含量变化与消落带坡地类型关系,探讨消落带不同坡地类型的磷素分布特征。结果表明：土＋石质型坡地磷素形态变幅较大,有效性高的Ca2-P、Al-P、Ca8-P及易活性的Fe-P易在土体中累积,加强了对水体富营养化的威胁;陡/缓坡裸岩型坡地上覆土体缺乏,有效磷和水溶性磷含量均较低,变化幅度较小;稳定滩涂淤泥型坡地有效磷含量有上升趋势。

| Abstract: | Combining relationship between the variation of soil phosphorus shape and content,and the types of water-level-fluctuating zone scope land,the distributional characteristics of phosphorus of different types of slope land in water-level-fluctuating zone were discussed. The results showed that the rangeability of phosphorus shapes in soil + lithic slope land was larger;Ca2-P,Al-P and Ca8-P with high effectiveness and Fe-P with high activity were easy to accumulate in the soil,thereby,the threat of eutrophicat... |
