| 摘要: |
| 1993年以来,对东部平原、云贵高原、蒙新高原等地区主要湖泊采取水样,进行了湖水矿化度分析，分析方法为容量分析法和火焰分光光度法。结果表明，中国湖泊矿化度的空间分布特点，大致依纬度及高度可分为青藏高原高矿化湖区、内陆高矿化湖区、东部低矿化湖区。从东向西存在矿化度逐渐增大的趋势，这种明显的区域分异既与自然环境的特点密切相关，又反映出湖泊本身的区域特色。 |

| Abstract: |
| Water samples were collected from the lakes in East plain, Yungui plateau and Mengxing plateau since 1993. Mineralized degrees were analyzed using volumetry and flame photometry. The spatial distribution of mineralized degree of the lakes in China can be roughly divided into 3 regions according to latitude and altitude, i. e. high mineralized degree region of Qinghai-Xizang Plateau, inner land high mineralized degree region and low mineralized degree region of the east China. The mineralized degree increases gradually from the east to the west. Such a distinct regional differentiation is related to the matural environment as well as the regional features of the lakes themselves. |
