本文探讨康定木格措景区热矿水的水热活动变化规律，热储特征和水化学组分的形成及 变化。初步分析表明，水热活动的强度由南往北逐渐减弱，主要表现在水温降低，泉口沉淀物减少， PH值由减性变为弱酸性和水质组分呈相应的规律变化。结合泉口沉淀物,用S,02温标法估算出 热储温度达165C_18CrC。通过论证水化学组成的形成和变化,对水热活动强度的差异作出解释。在此基础上，确定了康定木格措景区独立的热矿系统,并提出其成因模式。

Based on hydrogeochemical principle and method，the paper discusses the essential characteristics of the thermal mineral water，including: 1)hydrogeology activity pattern； 2) thermal reservoir feature and 3)formation and change of hydrochemical compostition. It is in?dicated from the preliminary analysis that the intensity of the hydrothermal activity progres?sively decrease from south to north，obviously appearing as the water temperature drop，the spring sedimentdecrease, PH value change from alkaline to neutrality and the relevant water quality change. Combined with the spring sediment，the thermal reservior temperature is esti?mated at 165 — 180°c using Si02 temperature scale. The authors prove the formation and change of the hydrochemical composition to explain the difference of the hydrothermal activi?ty and its genesis model is presented in Mugecuo Scenic Spot.
