Forests of West Virginia,U.S.A. and Shaanxi,China:a study in forest exploitation and recovery

美国西弗吉尼亚和中国陕西的森林:森林开发利用和恢复的研究(英文)

A review of the period of unregulated exploitation of forests in the state of West Virginia (U.S.) and in Shaanxi Province, PRC was presented. Economic and ecological recovery from exploitation has been different in the two regions due to basic differences in nature of the forest and in the degree and persistence of exploitive pressures. After a century since unregulated exploitation, West Virginia forests are well on the road to management for sustainability and conservation. Shaanxi's recovery from overuse and unregulated exploitation is less certain; forests are still in the early phases of ecological recovery there. Full recovery to a period of sustainability will take a century or longer. Suggestions are made for measures needed to enhance the forest recovery.

本文回顾了美国西弗吉尼亚州和中国陕西省无序开发时期的森林利用情况。由于在森林性质、在开发利用的压力大小和持续时间上的不同,导致两地区经济和生态恢复过程的差异。在无序开发约一个世纪之后,西弗吉尼亚森林已经走向可持续经营和保护阶段。由于过度利用和无序开发陕西的森林还不确定,目前森林仍处在生态恢复的初级阶段。完全恢复到可持续阶段需要一个世纪或者更长的时间。提出了促进森林恢复的一些措施。图6参18。
