摘　　要：根据３６０块标准地１９３株解析木资料，采用Ｃｈａｐｍａｎ—Ｒｉｃｈａｒｄｓ函数和二次项方程分别模拟平均树高和平均胸径的生长过程，运用迭代法分指数级编制了湖北省马尾松人工林林分生长过程表。经预测检验，精度很高。Based on the correlative analysis between Hubei early-rice annual bumper or poor harvest, SOI and atmopheric circulation, factors with strong influence upon the key periods of early-rice yield formation and of significant weather or biological meanings were found out. A prediction model of annual yield was also established.
