中文摘要：

从土壤有机质含量、土层厚度、坡向、海拔、坡度、土壤侵蚀模数等方面,运用数量化理论Ⅰ的方法,基于3S技术实现闽江流域杉木商品林林地质量的测定,并把测定结果划分为4个等级。结果表明,流域杉木商品林的林地质量主体以Ⅰ、Ⅱ级的林地为主,占92.62%,为流域的杉木林适地适树的经营提供科学依据。

英文摘要：

Chinese fir commercial forests＇ forestland productivity was measured based on geomatics and the application of Quantification Theory I , with the help of the fractors： soil organic matter, soil thickness, slope degree, altitude, aspect and soil erosion etc, and the results were divided into four grades. The results showed that the main body of Minjiang watershed＇s forestland productivity are grade Ⅰ and grade Ⅱ , which accounts for 92.62%, at the same time it provides scientific basis for the operation of matching Chinese fir to suitable site in Minjiang watersheld.
