贵州茂兰喀斯特原始森林地区25个雨水样品的化学组成研究表明,该区雨水的pH值为4.4～7.2,平均为5.1。雨水样品富NH4+、Ca2+和SO42-、Cl-。NH4+是最主要的阳离子,平均值为56.8μmol/L,占阳离子组成的26%～74%,Ca2+次之,平均值为14.8μmol/L,NH4+和Ca2+之和占了阳离子组成的71%～94%,SO24-是最主要的阴离子,平均值为39.2μmol/L,占了阴离子组成的69%～91%,Cl-次之,平均值为9.5μmol/L。SO42-和Cl-占了阴离子组成的71%～96%。与中国其他地区的雨水样品相比,茂兰地区雨水离子含量要低1～2个数量级;物质来源分析表明茂兰地区雨水中溶质主要来源于自然过程的输入,人为活动输入可以忽略不计。 |

Twenty-five rainwater samples from Maolan National Natural Reserve,Guizhou Province,have been characterized for their chemical compositions.The pH value varies from 4.4 to 7.2(mean value is 5.1).NH+4 and Ca2+ are the principal cations in the rainwater samples and their mean values are 56.8 and 14.8 μmol/L,respectively.The sum of NH+4 and Ca2+ accounts for 71%-94% of the total cations in the studied rainwater samples.SO2-4 with a mean content of 39.2 μmol/L is the predominant anion,and Cl-with a mean content of 9.5 μmol/L is the second important one.The sum of SO2-4 and Cl-together accounts for 71%-96% of the total anions.Compared with rainwater samples of other areas in China,the ion contents of the rainwater samples of Maolan National Natural Reserve are relatively lower in 1 to 2 order of magnitude,which may suggest that the contribution of human activities is negligible and the natural inputs are the major atmospheric sources in Maolan. |
