大山北麓阜康──准东山前倾斜平原地下水化学形成特点分析

ANALYSIS OF THE FORMING FEATURE OF GROUNDWATER CHEMISTRY AT FUKANG-ZHUNDENG PIEDMONT SLOPING PLAIN OF TIANSHAN NORTH FOOT

天山北麓阜康—准东山前倾斜平原第四纪松散堆积地下孔隙水含水系统水化学成分形成，主要受补给水源（冰雪融水，基岩山区较高矿化地表洪水）水化学性质影响，水中离子含量比例关系受矿化度影响明显，含水系统水循环交替迅速使排泄区中等矿化水淡化，地下水中Ｓｒ含量较高，普遍达到饮用矿泉水指标。

The formation of the chemical composition of the Quaternary loose deposited underground porous water system of the Fukang-zhundong piedmont sloping plain at Tianshan north foot is chiefly influenced by the hydro-chemical properties of the recharge water resource (melted ice-snow wter , rather highly mineralized surface floodwater in rocky mountainous area).The proportional relation of ionic content is evidently influenced by mineralization degree. The speedy interchange of the water system circulation makes the medium mineralized water in the drainage area being diluted and Sr content higher in the groundwater , and the indexes of potable mineral water are generally reached.
