以晋西北风沙源治理区五寨县柠条解析资料为基础进行回归分析，确定柠条枝径、枝高的最优生长模型，并用实测数据绘制枝径、枝高的连年生长量和平均生长量曲线，进行生长分析，结果表明，晋西北风沙源治理区柠条枝径以韦布尔模型为最优，枝高以坎派兹模型为最优，3a＜树龄＜8a时，柠条的生长速率相对较快；枝径连年生长量和平均生长量均在8a时增加迅速，枝高连年生长量和平均生长量最大值出现时间均较枝径提早，分别出现在4a和6a时。

Based on the data of the analytical trees in controlling area of wind and sand source of Northwestern Shanxi ,appropriate growth regular‐ity models of branch diameter and branch height were established by using SPSS 16.0 and Sigmaplot 10.0 software. The average increment and current annual increment curves were obtained to analyze the growth regularity. The results showed that the Weibull model could fit the growth process of branch diameter precisely ,whereas Gompertz model was the optimal model for the growth process of branch height. The growth rate was relatively high when the trees were between 3 and 8 years old. The current annual increment and average increment of branch diameter in‐creased apparently at the year of 8 ,the highest value of the current annual increment and average increment of branch height was earlier than those of branch diameter .
