| 摘 要： | 使用最小二乘曲线拟合法、相关分析和互相关分析法,对中山大学珠海校区滨海水循环综合试验基地监测的2006年8月~2009年6月溪流水温、水位及气温数据进行分析,发现小规模溪流水温-气温可以用线性模型和logistic模型较好拟合,水温波动相对气温存在2.0h位相延迟,水温-气温相关程度与水位值呈负相关关系;使用Morlet小波滤波、功率谱分析及小波方差计算等方法对水温与气温的日周期、半日周期及季节性周期成分进行研究,探讨其周期大小以及周期成分能量等问题。

| Abstract: | Temperature is a key factor affecting the environmental and ecological processes in the catchment.Based on the monitored and observed stream temperature and water level,and air temperature in Zhuhai Campus of Sun Yet-san University from August 2006 to June 2009,relationship between them was analyzed by using statistical methods,e.g.,least squares fitting,correlation analysis and cross correlation analysis.Linear model and logistic model were found suitable for fitting daily mean and daily highest temperatur... |
