| 摘 要： | 依据50年(1954~2003)和田绿洲的气象资料,应用灰关联分析,发现影响绿洲蒸发能力的主要因子是相对湿度与平均气温;在此基础上建立了回归模型。该模型模拟预测绿洲蒸发能力的变化精度较高,但需进一步改进。这种途径比逐步回归分析减少了分析工作量和上机时间。

| Abstract: | Base on the meteorological data from 1954 to 2003 in Hotan oasis,the grey relevancy analysis was applied to find out that the air temperature and relative humidity are the main factors for potential evaporation,and the multiple linear regression model was established.It was shown by variance and error analysis that the model can simulate and predict potential evaporation rather well,although some defects should be improved ulteriorly.Comparing with stepwise regression model,the proposed method has the advantages of simpler analysis and shorter computing time. |
