以乌梁素海和岱海2个不同类型湖泊上覆水中TIC、DIC、TOC、DOC的地球化学特征为基础,分析和探讨了2个湖泊上覆水的水化学特征和TIC、DIC、TOC、DOC的空间分布格局及其制约机制.结果表明,乌梁素海和岱海湖泊的水化学特征均属蒸发-浓缩类型,湖泊水体离子组分特征受控于流域的蒸发-浓缩作用及蒸发盐岩的风化作用;岱海TIC、DIC、TOC、DOC的含量范围分别为(0.93~1.16)×10~4、(0.78~0.90)×10~4、(0.07~0.63)×10~4、(0.07~0.48)×10~4μmol·L~(-1),乌梁素海TIC、DIC、TOC、DOC的含量范围分别为(0.18~1.00)×10~4、(0.03~0.81)×10~4、(0.10~0.51)×10~4、(0.04~0.32)×10~4μmol·L~(-1);2个湖泊上覆水中TIC和DIC含量的差异性是湖泊富营养化类型、自然地理区划、水文地质背景及水量收支方式等因素综合作用的结果;岱海上覆水中DIC、TIC、DOC、TOC受N、P、Si等3种营养盐的共同影响,乌梁素海上覆水中DIC、TIC、DOC、TOC主要受N的影响.

In this work, the concentrations, specie8 distributions and controlling mechanism of total inorganic carbon(TIC), dissolved inor-ganic carbon(DIC), total organic carbon (TOC) and dissolved organic carbon (DOC) were discussed on the basis of the overlying water hy-drochemistry character from the Wuliangsuhai and Daihai Lake. The results indicated that the overlying water hydrochemistry characters from the two lakes were controlled by the evaporation-enrichment process. The concentration ranges of TIC, DIC. TOC and DOC in the Daihai Lake overlying water were (0.93~1.16)×10~4,(0.78~0.90)×10~4,(0.07~0.63)×10~4 μmol·L~(-1)and (0.07~0.48) ×10~4 μmol·L~(-1),respectively;and (0.18~1.00) ×10~4,(0.03~0.81)×10~4,(0.10~0.51)×10~4μmol·L~(-1) and (0.04~0.32)×10~4 lcmol L-I in the Wuliangsuhai Lake, respective-ly. The differences of TIC and DIC reflected the eutrophication type, physical geographical regionalization, hydrogeologic setting and water incoming and outgoings of the two lakes. The concentrations and species distributions of TIC, DIC, TOC and DOC in the Daihai Lake were in-fluenced by the nitrogen, phosphorus and silicon; while they were mainly influenced by the nitrogen in the Wuliangsuhai Lake.
