采用标准地定位研究方法对杂木林及１代、２代、３代和４代杉木人工林土壤颗粒、土壤团聚体组成进行比较分析，结果表明：杂木林受人为干扰少，土壤颗粒及土壤团聚体组成较好，抗蚀性最好；但１代、２代、３代和４代分别是在杂木林及前１代林的采伐迹地上经再度干扰建立起来的，土壤结构破坏率加大，土壤团聚体稳定性减小，因而随着杉木林取代杂木林及杉木连栽代数增加，土壤抗蚀性减弱。
The soil and aggregate composition of the mixed forest and the 1st, 2nd, 3rd and 4th-generation Chinese fir plantations were analyzed by standard mapping method. The results showed that: the mixed forest was less disturbed by human intervention and soil particles and soil aggregated The body composition is better and the corrosion resistance is the best. However, the first, second, third and fourth generations are re-disturbed respectively on the cutting sites of the mixed forest and the previous forest, and the soil structure destruction rate is increased , Soil aggregates decreased in stability, so the soil anti-erodibility decreased with the replacement of Chinese fir plantation with alternate plantation algebra and continuous plantation alluvial growth of Chinese fir.
