浑江地区的现有森林,绝大部分经过掠夺式的采伐,火烧、人为或自然的破坏后而残留下来的。三十年来,在党的领导下,经过保护管理,森林得到了恢复,而且发生了树种更替。这些天然次生林是我们建设社会主义的物资基础,也是国家宝贵的后备森林资源。但是,这些资源中,也有些是低产和落后的,现就造成低产的原因及如何改造,提提我们的意见。 Most of the existing forests in the Hunjiang River area have survived predatory logging, burning, man-made or natural destruction. For the past 30 years, under the leadership of the party, forests have been restored through the protection and management, and tree replacement has taken place. These natural secondary forests are the material basis for our construction of socialism and also serve as a valuable backup forest resource for our country. However, some of these resources are also low-yielding and backward. The reasons for the low-yielding and how they are to be rebuilt now are our views.
