植物篱在减少坡耕地径流、控制土壤侵蚀和降低非点源污染方面具有重要的作用。采用中国科学院万州典型区生态环境监测重点站监测的三峡库区坡耕地皇竹草植物篱小区和对照小区连续6年的监测资料,研究了坡耕地皇竹草植物篱对土壤特性的影响,结果表明植物篱能有效地改善坡耕地土壤结构、提高土壤养分含量。植物篱的实施有利于三峡库区坡耕地的可持续利用。
Hedgerows play an important role in reducing sloping farmland runoff, controlling soil erosion and reducing non-point source pollution. The monitoring data of the hedgerow hedgerow plot and control plot of Huangzhu grassland in the sloping farmland of the Three Gorges Reservoir, monitored by the key stations of ecological environment monitoring in Wanzhou typical area of Chinese Academy of Sciences, were used to study the effects of hedgerows on the soil characteristics in the sloping farmland. The results It showed that plant hedgerows can effectively improve the soil structure of sloping farmland and increase soil nutrient content. The implementation of hedgerows is conducive to the sustainable utilization of sloping farmland in the Three Gorges reservoir area.
