摘　　要：基于线性倾向估计和多元非线性回归的理论,分析了巴中地区近40年的雨量、温度、日照的变化特征,同时结合油橄榄的生长习性对其进行了统计分析。结果表明,巴中地区近40年降水量的总体变化特征不是很明显,区域性变化不尽相同。年降水量的增多趋势对油橄榄生长的影响不大。年日照时数虽有下降趋势,但大致保持在1 400 h左右,对油橄榄的生长发育不会产生重要影响,影响油橄榄果实发育的关键时期(6～7月)的日照时数是略有增加的,这对油橄榄的生长是有利的。年均温度略有上升的趋势,将会促进该地区油橄榄的生长。综合以上气象要素的变化,巴中地区的气象生长条件对油橄榄生长是有利的,且在短时间内不会有较大的改变。Based on one linear and Multivariate Nonlinear Regression,nearly 40 years rainfall,temperature,sunshine characteristics in Bazhong were analyzed.Combined with the growth habits,a statistical analysis was conducted for it.The results showed that the rainfall in Bazhong was not very obvious in recent 40 years,regional changes were in different.The increasing trend of annual precipitation would have little effect on the growth of Olea europaea.Sunshine variation was decreasing,but it was staying about 1 400 h,which would not affect the growth of Olea europaea seriously,what＇s more,sunshine variation in Jun.to Jul.was increasing slightly,which would be helpful to it.Temperature changed slowly,and it would be advantageous for the growth of Olea europaea.Taking the above changes in meteorological elements,the Olea europaea region＇s climate in Bazhong was well,and it would not vary in a short time.
