摘要
为有效推进淮河流域坡耕地水土流失综合整治,对淮河流域内坡耕地现状进行调查与数据统计分析。结果表明:淮河流域现有坡耕地96.56万hm2,主要分布在桐柏大别山区、伏牛山区、沂蒙山区和江淮丘陵区,主要类型有石质坡耕地、土石质坡耕地、砂质坡耕地和土质坡耕地;通过全面分析坡耕地水土流失特点、危害以及综合整治中存在的主要问题,结合淮河流域已有水土保持成果和坡改梯治理试点经验,提出了不同类型坡耕地整治方向与主要技术模式。
To promote the comprehensive control of soil and water loss in Huaihe River Basin effectively,the paper illustrates the area,distribution,classification and the main features of slope farmlands in Huaihe River Basin based on the survey of the status quo and the comprehensive analysis of slope farmlands.The results show that the area of slope farmlands in Huaihe River Basin is 956.6 thousand hm2,which mainly distribute in the Tongbai-Dabie mountainous area,Funiu mountainous area,Yimeng mountainous area and Yangtze River Huaihe River hilly area.Lithoidal slope farmland,erathy lithoidal slope farmland,sandy slope farmland and earthy slope farmland are the main four types of slope farmland.Based on analyzing the characteristics and the harmfulness of soil and water loss,and the main problems during the comprehensive treatments,as well as the results of soil and water conservation and the experiences of transforming slope into terrace management,the paper proposes the administration ways and main technology patterns for different types of slope farmland.
