摘  要：
以岷江干旱河谷的理县段为研究对象,基于石砾含量、坡面稳定性、坡度等因子的综合分析基础上区划造林地和造林,然后从造林效果来评价和筛选不同造林模式的适应性。结果如下:(1)干砌石水平阶梯工程+大苗客土种植模式适用于石砾含量70%以下、堆积体厚度在0.5 m~2.0 m之间、坡度在25°~35°之间、降雨量600 mm以下的受灾林地。(2)简易排水工程+水平夯土阶梯工程+大苗客土种植适用于石砾含量70%以下、堆积体厚度在1.0 m以下、坡度在25°~35°之间、降雨量600 mm以下的受灾林地。(3)浆砌石挡墙阶梯工程+大苗客土种植适用于治理石砾含量50%以上、堆积体厚度2.0 m以上、坡度在25°~35°之间、降雨量600 mm以下的受灾林地。本文总结出了一套科学、可行的森林植被恢复技术,能为干旱河谷的植被恢复工作提供技术参考。

摘  要：
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.
