用平均解析木测定材料研究表明，杉木不同种源的地上干材生长和生物量有显著置信的差异。变异具有纬度和温度（热量）影响为主，冷暖变化明显的地理效应趋势，并可用线性回归模型表示。在较差立地条件下，９年生时，广西融水、湖南江华、贵州绵屏四川犍为等优良种源，比当地同龄对照杉木生长量高，高径比大，冠径比小，树皮率低；每百平方米林分地上部分和干材部分的生物量（鲜重，干重）分别增加２２．４２％－３２．１９％和３８．０１％－７７．１９％ Studies using average analytical wood assay materials showed significant and convincing differences in the growth and biomass of aerial dry matter from different provenances of Chinese fir. Variation has the latitude and temperature (heat), the obvious changes in the geographical trend of cold and warm, and can be expressed by linear regression model. Under poor site conditions, 9-year-old Guangxi Rongshui, Hunan Jianghua and Guizhou Mianping Sichuan were the best provenances. Compared with the same age, Chinese fir had higher growth, larger height-diameter ratio, smaller crown-diameter ratio, The biomass (fresh weight and dry weight) of aerial parts and dry parts per hundred square meters increased by 22.42% -32.19% and 38.01% -77.19% respectively,
