Every year, forest fires and severe storms cause a great deal of damage to forests in the northwestern United States. One way of dealing with the aftermath of these disasters is called
salvage logging, which is the practice of removing dead trees from affected areas and using the wood for lumber, plywood, and other wood products. There are several reasons why salvage logging
is beneficial both to a damaged forest and to the economy.
每年，在美国西北部，森林火灾和一些严重的暴风雨会给森林造成严重的损害。而措置这些灾难造成的损害的体例之一被称为收受接管性砍伐。收受接管性砍伐是指把受损地域的已经衰亡的树木一走，用作建造木材、胶合板或者其他木材产物。有一些理由让我们相信收受接管性砍伐无论对于受损的森林仍是对于经济成长都是有益处的。
First, after a devastating fire, forests are choked with dead trees. If the trees are not removed, they will take years to decompose; in the meantime, no new trees can grow in the cramped
spaces. Salvage logging, however, removes the remains of dead trees and makes room for fresh growth immediately, which is likely to help forest areas recover from the disaster.
首先，每次森林火灾之后，森林都被死树堵住了。如不美观不把这些树移走，那么它们需要数年的时刻才会侵蚀。在这个时刻里，就不涣有新的树木能够在这些狭小的空间发芽发展了。然而，收受接管性砍伐则可以把这些死树移走，迅速地位新生的树木供给发展的空间。这样做，有助于辅佐森林从火灾中恢复。
Also, dead trees do more than just take up space. Decaying wood is a highly suitable habitat for insects such as the spruce bark beetle, which in large numbers can damage live, healthy spruce
trees. So， by removing totting wood, salva
