杉木种子涩籽的空间变异性研究

运用“Ｋｒｉｇｅ”空间内插技术，对福建省杉木种子涩籽率地理流行趋势进行分析．结果表明：“Ｋｒｉｇｅ”内插技术拟合优度达９９．９％．能真实反映杉木种子涩籽率的地理流行趋势，清晰地区划出以建瓯、建阳为中心的低涩籽率区域和永太泰、闽侯为中心的高涩籽率区域，为福建省杉木种子园的合理布局提供了理论依据．

STUDY ON SPATIAL VARIABILITY OF CHINESE FIR STERILE SEEDS

Data of Chinese fir sterile seeds from 25 sites in Fujian were analyzed with the method of "Krige" technique analysis.The results showed that the regression precision of "Krige"spatial interpolation technique was 99.9%;the method could reflect the geographic epidemic trend of Chinese fir sterile seeds;the method could clearly drew out the lowest and highest sterile seeds regions; and the method could be a powerful tool for establishing the habitat of Chinese fir seeds garden.
