汉西林业局建于1958年,三十多年来在森林采伐方式上经历了多次反复。1981年省委省政府决定把秦岭林区划为水源涵养林。由于对决定理解不深,由片面强调木材生产转向了过分强调森林的生态效益,把利用与培育森林的社会、经济、生态效益对立起来,不分林分状况,立地条件,在主伐方式上千篇一律地采用择伐。由于单一择伐,在产量不减少的情况下,使采伐面积逐年增加,造成可利用资源越来越少,加速了企业“两危”,而且大面积范围内实行林冠下更新也
The Hanxi Forestry Bureau was established in 1958 and has undergone many iterations over the past 30 years in the field of forest harvesting. In 1981 the provincial party committee and government decided to Qinling forest water conservation forest.

As a result of single-choice cutting, yield does not decrease in the circumstances, the logging area increased year by year, resulting in fewer and fewer available resources, accelerating the “two jewels”, but also within a large area under the canopy update
