Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.
目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式,一是运用同位素地质温度计原理,利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系,对湖泊古水温做定量研究;二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温;三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。

Examination of the equilibrium status of a point in the salt water zone and the description of piezometric heads at two points in both the salt water and fresh water zones reveals that the location of the fresh water-salt water interface in a coastal homogeneous, isotropic unconfined aquifer can be estimated based on piezometric heads at two points in the same vertical line tapping respectively the salt water zone and the fresh water zone (from the water table to the interface) when the groundwater flow system is in a steady state and satisfies the Dupuit assumption.
通过考察咸淡水界面之下咸水带任意点的压力平衡关系和咸水带及淡水带任意点的水头描述得知,当地下水流处于稳定状态且满足Dupuit假设时,可以根据同一垂直线上界面之下咸水带任意点的咸水测压水头和界面之上淡水带任意点的淡水测压水头确定滨海均质各向同性潜水含水层咸淡水界面的位置。
