岷江上游林区地处益地西缘山地、高山峡谷向高原丘陵过渡的地带,海拔高差悬殊,地形复杂多变,切割强烈,生态条件差异很大,是我省西部原始林区的重要组成部分.由于地处江河上游,涵养水源,保持水土的作用十分突出,素有川西平原“天然屏障”之称.在采伐利用森林的同时,狠抓更新工作,早日建立新的生态平衡,是林业建设的迫切任务.自1955年开始森林更新以来,已形成一支较强的营林队伍,积累了较丰富的经验.
The upper reaches of the Minjiang River is located in the western margin of the benefits of the mountains, alpine valleys to the plateau hilly transitional region, the altitude difference is poor, complex and changeable terrain, cutting strong, great ecological conditions, is an important component of the original forest area Partly because it is located in the upper reaches of the rivers and conserves water and keeps the role of water and soil well, it is known as the “natural barrier” in the western Sichuan Plain. While cutting and utilizing the forests, it is necessary to pay close attention to the renewal work and set up a new ecological balance as soon as possible The urgent task of construction Since the forest renewal started in 1955, a strong silo team has been formed and a wealth of experience has been accumulated.
