陇南山区农林复合模式划分与种植结构研究

甘肃省陇南坡耕地占总耕地面积的80.15%。坡耕地及不合理的耕作方式是造成水土流失的主要原因之一，在山坡地及梯田中进行农林复合栽培，可提高土地产出率，有效防治水土流失。根据生产方式和栽培结构将陇南山区农林复合栽培的模式种类划分为林药复合、林粮间作、田间地埂利用、果菜种植、特种林粮复合、庭院经营、小流域综合治理、林草复合等8种农林复合栽培模式，以便在坡改梯、退耕还林等生态工程中较好地应用复合农林业技术。

Research on Mode Partition and Planting Configuration of Agroforestry in Mountainous Area of Longnan

Slope land occupies 80.15 percent of total arable land in mountainous area of Longnan region,Gansu Province. The slope plantation and farming manner is one of reasons which caused soil and water loss ,planting of agroforestry on the slope land and terrace may increase the production of unit produce ,prevent soil and water loss efficiently. Based on the production mode and configuration of planting,the mode of agroforestry in Longnan mountainous area was divided into 8 modes,forest and herb ,forest and grain ,the mode of using terra bank ,fruit and vegetable ,special forest and grain ,the mode of courtyard economy,management of small watershed ,forest and grass and so on ,the technology of agroforestry planting will be applied in the project of changing slope to terrace and grain for green.
