S722.8+3; 以浙江省庆元县庆元林场杉木种子园13 a种子产量系列和影响杉木种子园产量的生物因(X1～X3)、气象因子(X6～X14)及立地因子(X4～X5)等资料为依据,在应用回归分析方法筛选构成影响产量主导因子的基础上,分别研建了杉木种子园产量的多元线性模型:杉木种子园年度单位面积种子平均产量Y1=60.047 46+0.001 67X7(年降水量)-0.116 95X8,9(开花期低温指数)-0.015 79X10(开花期降水量)+0.008 16X12(开花期日照时数)+0.004 44X13(高温干旱期降水量)-2.268 72X14(7～8月份平均气温);种子园小区年度种子产量Y2=-603.427 10+34.142 67X4(小区坡向)+0.072 20X6(≥10 ℃...
