摘 要 ：运用趋势面分析的方法,对全国杉木种源试验55个试点的43个共同种源的生长结果进行分析。结果表明,高次傅里叶趋势面比多项式趋势面更能反映种源的地理变异,清晰地区划出了以湘黔桂交界地区、闽北地区和四川盆地地区为中心的三个杉木高产种源地区和以江浙皖沿海地区、陕豫鄂交界地区和滇西地区为代表的杉木低产区域,减少人为影响,为种源区划分提供了有力的工具.

Abstract:Data of 43 Chinese fir provenamces from 55 experimental sites was analyzed with the method of trend surface analysis(TSA).The result showedthis Fourier trend surface analysis usually had higher precision than that ofpolynomial,it could clearly drew out best and lower provenance regions,thesubject effect on distinguishing provenance could be reduced,and it wouldbe a powerful tool for provenance research.
