通过 建立径 流场，进行 不 同抚 育方 式 对 杉木 人 工 林水 土 流失 、土 壤 肥力 及 林 木生 长５ ａ 的定位 研究，结 果表明： 传统杉木 抚育方式 导致了 杉木幼林 地严 重水 土流 失，不 同抚 育方 式林地 水土流失 表现为 ：扩穴连带 抚育＞ 块状抚 育＞ 不抚 育；随 抚育 破土 面 增大 ，林 地表 层土 壤砂质 化愈明 显，林地养 分含量 下降，抚育 对林地 的干扰主 要集中 在０ ～２０ ｃ ｍ 土 层；不同抚 育方式杉 木生长效 应表现 为：扩穴连 带抚育 ＞ 块状 抚育， 随时 间推 移，抚 育对 杉 木生 长 的影 响逐 年缩小 ，抚育方 式是影响 杉木人 工林长期 生产力 维持的重 要人为因 子。 Soil erosion, soil fertility and 5-year-old tree growth were determined by establishing runoff field and different tending ways. The results showed that the traditional ways of fir firing led to serious water and soil loss in young Chinese fir plantations, soil erosion in different tending ways The results showed that: the expansion of the hole associated with tending> block tending> no tending; with tending to raise the soil surface, the more obvious sandy soil surface woodland, forest nutrient content decreased, tending on woodland mainly concentrated in the 0 ~ 20cm soil layer The effect of different tending ways on the growth of Chinese fir was as follows: expanding hole together and tending> block tending. With the passage of time, the influence of tending on the growth of Chinese fir decreased year by year. The tending method was the important human factor that affected the long-term productivity of Cunninghamia lanceolata plantation.
