分析连续3年的黑河水温、水质,为水生动物保护与利用提供基础数据。该流域水质溶氧8.64~12.63 mg/L,p H 6.70~8.33,浊度0.6~2.5 NTU,可满足水生动物的生存和生长。3年日平均水温2.78~21.02℃。整体呈正弦曲线走势。水温1月最低,8月最高,极值出现时间大体相近。夜间日水温最高,白昼最低。2013年温差最大,2014年最小。水温随气温变化而变化。一般3~10月月平均水温低于气温,11月~翌年2月月平均水温高于气温,3月和10月前后水温和气温基本持平,最大差值1.5~2.5℃。温度具有明显的昼夜变化、季节变化和年变化差异,以年周期变化为主。水温变化与水生动物生活习性相适应。
The water temperature and water quality in Heihe River for three consecutive years were analyzed to provide basic data for aquatic animal protection and utilization. The water dissolved oxygen in the watershed is 8.64 ~ 12.63 mg / L, p H is 6.70 ~ 8.33 and turbidity is 0.6 ~ 2.5 NTU, which can meet the requirements of survival and growth of aquatic animals. 3-year average daily temperature of 2.78 ~ 21.02 ℃. The whole curve was sinusoidal. The lowest water temperature in January, the highest in August, the extreme appearance time is generally similar. The highest water temperature at night, the lowest daytime. The temperature difference was the highest in 2013 and the lowest in 2014. Water temperature varies with temperature. The average monthly mean water temperature from March to October is lower than the air temperature. The monthly average water temperature in February from February to November is higher than the air temperature. The water temperature and air temperature are basically the same between March and October, with the maximum difference of 1.5 to 2.5 ℃. The temperature has a significant diurnal variation, seasonal variation and annual variation, mainly in the annual cycle. Water temperature changes and aquatic animal habits to adapt.
