- 摘要:
- 坡耕地的合理利用与保护是三峡库区生态环境和农业可持续性发展的关键。以植物篱生态过滤网带技术、粮经果复合垄作技术、地下地膜截水墙技术为核心的坡耕地持续性利用技术，不仅培肥土壤，增加土壤含水，减少水土流失，而且显著提高土地系统生产力，发挥了较好的生态经济效益，可为三峡库区坡耕地的利用与保护提供技术支撑。
- Abstract:
- In the Three Gorges Reservoir,cultivated land resource is very limited,of which a rather high proportion is slope cropland.Due to poor cultivation and management,soil and water loss is a serious problem on both eco-environment and sustainable agricultural development.Preventing soil erosion and improving productivity of slope cropland are the main targets of sustainable utilization technology including contour tillage of wide ridge and furrow covering,underground plastic sheet wall,agro-foresty and hedgerows formed vertical agricultural structure of slope cropland.The results showed that this technology has good ecological and economical effects,could improve the soil fertility, increase the soil effective-water content, protect the soil and promote the land productivity.It should be widely extended in the Three Gorges Reservoir.
