综合利用我国红壤资源防治水土流失

The Integrated Utilization of Red Soil Resources and Control of Soil Erosion in China

红壤地区长期以来,由于不合理的土地利用,导致了严重的水土流失,土壤生产力下降。根据土壤利用方式可把土壤侵蚀分成农用坡耕地侵蚀,林果园等坡地侵蚀和裸地稀疏林地侵蚀这三种类型。土壤综合利用是防治水土流失的关键,为此,本文探讨了开发不同丘陵地综合利用的途径和建立“一丘多用”的生态农林牧业的策略。

In the red soil region, irrational land use has resulted in serious water and soil erosion and a decrease in soil productivity. Based on the soil use patterns, soil erosion can be divided into three types: i. e. erosion on agriculturally-cultivated slope lands; erosion on forest and orchard lands and erosion on bare and Sparse wood lands. The integrated utiliza- tion of soils is the key to controlling soil erosion. For this reason, this paper discusses the approaches of developing integrated use of hilly lands and the strategies of establishing 'one hill with multiple use' of ecoagri culture.
