We choose the forest appearance tidiness , representative stands serving as standard plots , 40 stands were set up at qinling , hanzhong , huanghong in shaanxi respectively , measure every tree in the stands , measure the actual increase by the dominance tree , the time series model of individual age and diameter of quercus variabilis was established according to the actual diameter of quercus variabilis population by the fluctuant time series , the comparison of simulation and reality value of the every stand of quercus variabilis population diameter increase through the four models , the average simulation difference within 1 . 5 % , the accuracy is 97 . 8 % the simulation effect is better
在陕西的秦岭、汉中、黄龙地区选择林相整齐、有代表性的地段作为标准地，设置样方40个，对各样方内的林木进行每木检尺，通过优势木解析的方法，测得栓皮栎种群胸径的实际生长量，运用起伏型时间序列分析，建立了栓皮栎种群个体年龄与胸径生长的时间序列模型，四个模型所得的各个样地栓皮栎胸径生长的模拟值与实际值进行比较，其模拟平均误差都在1 . 5 %以内，平均精度达到97 . 8 % ，模拟效果较好。
