三峡水库蓄水后水温时空变化特征及其生态影响
Spatio-temporal characteristics of Three-Gorges Reservior and its influences on the eco-environment
为了从整体上把握三峡水库蓄水以来下泄水温变化情况,本文分别从时间和空间两方面来分析水温的变化规律,运用SPSS统计软件对三峡大坝出入库水文站的多年月平均水温过程进行了perason相关系数的计算;根据相 关公式估算了水库垂向上的水温分布并结合现场监测数据进行分析。 结果表明:三峡水库库区近坝段主槽没有出现水温分层;多年月平均水温变化幅度较小,下泄水温在不同时期分别出现了“滞热”和“滞冷”现象。
his paper investigated spatio-temporal distribution characteristics of three-Gorges Reservior by pearson correlation coefficient analysis of SPSS,and quantitative calculated the variance of monthly average water temperature.results showed that the main channel near the dam does not appear the phenomena of water temperature delamination;the variation amplitude of monthly average temperature is not serious, the outflow temperature delay between different period is obvious.
