摘　　要：为了加强水土流失治理,提高水土保持植被的适宜性和存活率,文章针对黄土高原特殊地貌的恶劣气候环境,以陕西省府谷县为例,在分析区域地形地貌和立地类型、水土流失特点的基础上,对梁峁坡耕地、沙盖黄土丘陵区和河谷阶地川台等3种地貌的林草建设模式进行了探讨,提出:(1)在梁峁坡耕地采用经果林建设模式;(2)在沙盖黄土丘陵区采用麻黄人工栽培建设模式;(3)在河谷阶地川台地采用生态经济林建设模式。研究结果可为黄土高原不同地貌的水保林建设积累经验并提供借鉴。In order to strengthen soil and water conservation control,it is nessary for improving the suitability and survival rate of vegetation,this paper takes Fugu County of Shaanxi Province as an case considering its harsh climate environment and unique landforms on the Loess Plateau.Through systematic analysis of regional geomorphology,site-specific characteristics,and soil erosion patterns,the forest-grass restoration models were discussed in three typical landscapes(loess ridge slopes,sandy-loess hilly areas,and river valley terraces).It was proposed that:(1)adopting Fruit-based agroforestry models for loess ridge slopes;(2)adopting Ephedra cultivation in sandy-loess hilly region;(3)adopting eco-economic forestry development in valley terrace basins.These results provide actionable references for the construction of water conservation forest in different landforms of the Loess Plateau.
