摘 要:通过野外实地调查及采样,采用NaOH熔融—火焰光度法及NH;OA;浸提—火焰光度法分析哈巴雪山自然保护区土壤全钾及速效钾含量,结果表明哈巴雪山土壤A层、BC层土壤全钾含量与海拔高度之间存在着较为显著的线性相关,相关系数均≥0.850,B层全钾含量分布则与海拔高度相关性不大,R^(2)=0.5039;A层速效钾含量明显的高于B层、BC层,A层速效钾含量随海拔升高而增加的趋势较为明显,散点分布范围在0~700 mg.kg^(-1)之间。Through field investigation and sampling, the total potassium and quick potassium content were analyzed by NaOH melting-flame photometry and NH;OA;extraction-flame photometry. The results showed that there is a significant linear correlation between the A and BC layers and the altitude,with a correlation coefficient of ≥0.850. The total potassium content distribution in layer b showed little correlation with altitude, with R^(2)=0.5039;the content of quick effect potassium in layer A is significantly higher than that in layer B and BC. The trend of quick effect potassium content in layer A increases with altitude, and the scatter distribution ranges between 0 and 700 mg.kg^(-1).
