This study evaluated the soil chemical characteristics and fertility of Pinus massoniana plantations in different ages with the Grey Relational Analysis( GRA). The results showed that 11 plots were acidic soil,in which the contents of total P,available P,total K,available K,exchangeable Ca and Mg,available B,available Zn and available Mn were very poor or poor,the contents of organic matter,total N andalkali-hydrolyzable N were below the medium level,the contents of available Cu and available Fe were above the medium level. The grey relation of soil fertility comprehensive index in 11 plots were distributed mainly in the range of 0. 385 ~ 0. 709,with the average value being 0. 514,and soil fertility was at the Ⅳ( poor) level. One plot was classed as Ⅱ( good),two plots were Ⅲ( average),six plots were Ⅳ( poor),and two plots were Ⅴ( worse). The soil fertility of eight-year-old Pinus massoniana plantations was the highest in Leli Forest Farm of Tianlin County and was the poorest in Paiyangshan Forest Farm. The higher the growth rate of Pinus massoniana at the same age,the lower the soil comprehensive fertility.
