| 摘要: |
| 依据60处地点野外观测水质化验数据，分析了地下水及土壤中各种离子含量之间的相互关系，结果表明，和田绿洲地下水硬度和土壤碱性主要受镁离子影响；土壤钾钠离子含量大于11.013 mg/kg或氯离子含量大于4.966 mg/kg时，农田产量会下降。 |

| Abstract: |
| Based on the field observation data from 60 locations and chemical test data from 3 plots in Hotan Prefecture,the relationships between several ions in groundwater and in soils are analyzed.It is shown that the hardness of groundwater quality and soil alkalinity are affected mainly by ion Mg and if ion K or Na content is higher than 11.013 mg/kg the crop yield would be decreased. |
