2014年-2019年乌鲁木齐河上游水体矿化度 的时空格局

Temporal and Spatial Pattern of Water Mineralization in the Upper Reaches of Urumqi River From 2014 to 2019

乌鲁木齐河是新疆乌鲁木齐市的重要水源地。为了解乌鲁木齐河上游水体矿化度在不同时间尺度的变化特征,在上游上、中、下段3个水质监测断面(跃进桥、英雄桥、青年渠)开展连续6年(2014年~2019年)的月度矿化度监测。结果表明,各年份及各监测断面的水体矿化度均具有明显的月变化特征,且总体变化趋势相近,表现为1月~6月逐渐下降,7月~8月最低,随后波动上升。6年间水体矿化度年平均值呈2次下降趋势,且呈现从上游上段、中段至下段逐渐降低的特点。总体而言,乌鲁木齐河上游水体矿化度具有较规律的时空变异特征。

Urumqi River is an important water source in Urumqi,Xinjiang.In order to understand the change characteristics of the water mineralization of the upper reaches of the Urumqi River at different time scales,three water quality monitoring sections(Yuejin Bridge,Hero Bridge,Youth channel)in the upper,middle and lower reaches of the upper reaches have been carried out for 6 consecutive years(2014~2019)Monthly salinity monitoring.The results show that the salinity of water bodies in each year and each monitoring section has obvious monthly changes,and the overall change trend is similar.It shows a gradual decline from January to June,the lowest from July to August,and subsequent fluctuations increase.During the 6 years,the annual average of water mineralization showed a downward trend twice,and showed a characteristic of gradually decreasing from the upper,middle and lower upstream.In general,the water mineralization in the upper reaches of the Urumqi River has regular temporal and spatial variation characteristics.
