通过采集浙江省安吉县2种典型板栗林不同坡面位置表层土壤样品,分析有无截水工程措施板栗林土壤特性之间的差异。结果表明:坡面截水工程措施对板栗林沟间坡面土壤性质没有明显的改善作用,其土壤有机质、速效钾和有效磷质量分数分别比无措施板栗林低5.88%、6.68%和33.54%,砂粒质量分数比无措施板栗林高10.57%。板栗林侵蚀地坡度的急剧变化导致坡面不同位置土壤养分和土壤颗粒组成的明显变化,2种板栗林坡度增加段土壤养分质量分数低,土壤砂粒质量分数相对较高;而坡面截水工程措施使得坡面土壤颗粒组成相对稳定,但要改善林地土壤肥力还必须与其他水土保持措施相结合。
By analyzing the soil samples from two typical chestnut stands in different slope areas in Anji County, Zhejiang Province, the differences in soil characteristics between the two treatments were analyzed. The results showed that: the engineering measures of slope water cut had no significant improvement on the soil properties of chestnut grove slope, the soil organic matter, available potassium and available phosphorus were 5.88%, 6.68% and 33.54% , The sand mass fraction 10.57% higher than the non-measures chestnut forest. The rapid changes of the eroded slope of chestnut forest resulted in significant changes of soil nutrients and soil particle composition at different positions of the slope. The soil nutrient content of the two species of chestnut forest increased with the lower soil mass fraction, and the soil sand mass fraction was relatively high. However, The measures make the composition of soil particles on the slope relatively stable, but the improvement of soil fertility in forestland must also be combined with other soil and water conservation measures.
