【摘要】 赣南山地红壤丘陵区是我国南方水土流失的严重地区之一,江西省信丰县崇墩沟项目区因大面积低效林分布、山地果园建设和稀土矿开采造成严重水土流失,具有区域的代表性和典型特征。以崇墩沟流域为对象,通过全面调查及系统分析诊断,查明生态系统中引起水土流失的主要原因,采取优化土地利用方式,配置适宜生物措施类型,并与工程技术措施组装配套,建立了一套较为完整的生物措施治理水土流失的技术方案,为赣南山地及同类地区生物措施治理水土流失提供参考。更多还原

【Abstract】 Mountain red soil region in southern Jiangxi Province is one of the most serious regions of soil erosion in south of China.Chongdun watershed project area in Xinfeng County possessed representational and typical characteristic for its serious soil erosion caused by large area of low functional forest distributing,hillside orchard constructing and rare earth mine exploitation.Based on the general investigation and systemic research on natural background of project area,the primary factors effected soil erosion were found out,and a technical plan on controlling soil erosion by optimizing land using methods,collocating feasible plants and biological measures combined with technical measures was presented.This experience could be used for reference for areas having similar background.更多还原
