设置普通山地与茶园套种薄壳山核桃2种经营模式，研究结果表明，山地上坡由于长年雨水的冲刷，养分流失严重，导致上下坡养分差异巨大，普通山地下坡土壤营养元素含量为中上坡的1.09～5.59倍，茶园的上下坡均在1.01～1.24；山地纯林的造林成活率上坡明显低于中坡和下坡，且存在显著差异；茶园套种上坡同样低于中下坡，但没有达到显著差异；同坡位茶园套种的薄壳山核桃树的地径、苗高、分枝和冠幅均大于山地纯林栽培。两者不同坡位之间表现均为下坡＞中坡＞上坡，但山地栽培不同坡位间存在显著差异，而茶园不同坡位间差异不显著。

Two models of Carya illinoinensis planted in the mountains and tea plantations were studied in this paper. Results showed that nutrient loss serious on the top of slope due to years of rainfall erosion, cause a huge difference in the nutrient between the top and bottom of slope. Content of nutrient elements of soil on downhill slope is 1.09~5.59 times than top of slope, tea plantation on the downhill were 1.01~1.24; pure forest afforestation survival rate of ascent was significantly lower than that in middle and lower slope of mountain, and exist significant differences; while planted in tea plantation uphill was also lower than in the downhill, but not existed significant difference; with the same slope position, planted in tea garden of shell pecan tree ground diameter, seedling height, branch and crown were greater than pure mountain forest cultivation. There were significant differences between the different slope positions, there were significant differences between different slopes of mountain cultivation, there were no significant differences between the different slopes of the tea plantation.
