| 摘 要： | 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。

Influence of Sloped Land with Living Hedges to Soil Characteristics of the Three Gorges Reservoir Area |
| |
| Abstract: | Living hedges on sloped land have an important function on the aspects of runoff reduction,soil erosion control and non-point source pollution reduction.The paper studies the influence of sloped land with living hedges to the soil characteristics by using the monitoring data of sloped land plots with living hedges and check plots in the Three Gorges Reservoir area monitored by Wanzhou Key Monitoring Station of Typical Ecological Environment of the Chinese Academy of Sciences in six years.The outcomes show that the living hedges on sloped land can effectively improve the soil structure of sloped land and increase the content of soil nutrient.The implementation of living hedges is favorable to the sustainable utilization of sloped land in the reservoir area. |
