横断山北部生态脆弱区土壤磷素空间分布特征

Phosphorus plays an important role in the course of plant growth,and is a key factor that influences crop output and so is an important index to evaluate soilfertility.Furthermore,it can contribute to nonpoint source pollution of surface waters.Many researches indicated that parent material and fertilization quantity were the two primary factors to determine soil phosphorus content.There had been many researches on the spatial distribution regarding soil phosphorus content and it's influencing factors in re...
