Abstract: In this paper,Lixian section in the arid valleys of the Minjiang River was taken as the research object. Based on the comprehensive analysis of gravel content,slope stability,slope factor and so on,forestation land division and afforestation were conducted,aiming to evaluate and screen the adaptability of different afforestation models according to the effect of the afforestation. The results were as follows:(1) Dry stone horizontal step engineering + seedlings soil planting mode was suitable for the affected forest fields in gravel content below 70% and with the deposit thickness between 0.5 and 2 meters,the slope between 25~35 degrees and rainfall below 600 mm. (2) Simple drainage engineering + level soil planting seedlings of rammed earth ladder project was suitable for the affected forest fields in gravel content below 70%,and with the deposit thickness below 1.0 m,the slope between 25~35 degree,and rainfall below 600 mm. (3) The masonry retaining wall with ladder engineering + seedlings planting was suitable for the affected forest fields in gravel content above 50%,and with the thickness of 2.0m above accumulation body,slope between 25~35 degrees,rainfall below 600 mm. Besides,a set of scientific and feasible technology was put forward for the restoration of forest vegetation,being able to provide technical reference for the dry valley vegetation recovery.
