摘要:
应用趋势面分析对1991年1月–1994年12月期间察尔汗盐湖晶间卤水水位的时空变化进行了研究。结果表明,1、2次趋势面反映了察尔汗盐湖晶间卤水水位变化的背景;3–5次趋势面能够较确切的反映察尔汗盐湖采卤过程中晶间卤水水位的变化规律。1次剩余分析所反映的正、负异常带和5次趋势分析所反映的高、低水位带在研究区的分布规律,充分说明了随着采卤的不断进行,晶间卤水的低水位带逐渐向研究区的南部移动同抽卤有关,研究区通过东西方向上晶间卤水的补给明显大于南北方向的补给。

Abstract:
In this article, the fluctuation of intercrystalline brine-level with time and space was studied by utilizing trend surface analysis of the data collected from January, 1991 to December, 1994, in Qarhan salt lake. The results indicate that the first and second trend surfaces reflected the background of the intercrystalline brine-level fluctuation. At the same time, the third, fourth and fifth trend surfaces can be used to interpret the fluctuation of the intercrystalline brine-level during the time of mining brine in the salt lake. The distribution of the positive and negative abnormal belts of the first trend surface residual analysis and the high and low water level belts of the fifth trend surface analysis fully illustrated that the low inter crystalline brine-level belt that moved slowly towards the south with successive mining was mainly attributed to brine mining. The amount of supply for intercrystalline brine from the east-west direction was no doubt much more than that from the south- north direction.
