/ The removal of riparian vegetation along small streams affects the thermal regime of the stream and consequently the biota within it. A simple regression model for mean monthly temperature after riparian canopy removal, based on conditions prior to removal, is presented. The model is determined to have an accuracy of +/-2 degrees C 95% of the time over the temperature range 0.7-17 degrees C. The regression also predicts a switching point at 3 degrees C, below which postharvesting temperatures are colder than prior to harvest. The ability to predict postharvest stream temperatures based on preharvest air temperatures is also evaluated. Management implications of thermal effects due to riparian removal are discussed.KEY WORDS: Stream temperature; Temperature model; Prediction; Air temperature; Thermal change; Riparian canopy removalhttp://link.springer-ny.com/link/service/journals/00267/bibs/24n1p77.html
/ 沿小溪的河岸植被清除会影响溪流的热状况,进而影响其中的生物群落。本文提出了一个基于清除前状况的河岸树冠层清除后月平均温度的简单回归模型。该模型在0.7 - 17摄氏度的温度范围内,95%的时间内精度为正负2摄氏度。回归还预测了3摄氏度的转换点,低于该点收获后的温度比收获前更冷。还评估了基于收获前气温预测收获后溪流温度的能力。讨论了河岸清除造成的热效应的管理意义。关键词:溪流温度;温度模型;预测;气温;热变化;河岸树冠层清除http://link.springer-ny.com/link/service/journals/00267/bibs/
