摘要
This paper reviews various forestry practices in Jilin Province, China. The authors emphasize the rich natural diversity of Jilin and the need to focus research efforts on understanding the potential of native species to meet the needs of land-management agencies involved in forest resource exploitation and ecological restoration. The native species of China hold great potential, and deserve more research attention, for meeting these needs. The introduction and testing of exotic species should be dbne only under rigorous scientific testing and after comparison with native species prior to operational introduction into forestry in order to avoid unwanted ecological consequences, including potential problems with alien invasives and pest introductions. The authors also emphasize the need to maintain viable （e.g., genetically diverse and reproductively fit） natural populations of native species in order to protect China＇s valuable natural diversity and maintain the potential of native species to function as future seed sources for local forest and ecological restoration activities.
这篇论文在吉林省考察各种各样的林地惯例，中国。Theauthors 强调吉林和需要的富有的自然差异在理解本国的种类的潜力满足涉及森林资源利用和生态的恢复的陆地管理机构的需要上集中研究努力。中国的本国的种类保持大潜力，并且值得更多的研究注意，为满足这些需要。介绍并且异国情调的种类测试应该在运作的介绍以前与本国的种类仅仅在严密科学测试下面并且在比较以后被做进林地以便避免讨厌的生态的后果，包括有相异的 invasives 和害虫介绍的潜在的问题。作者也强调需要维持可行(例如，遗传上多样并且 reproductivelyfit ) 种子为本地森林和生态的恢复活动采购以便保护中国的珍贵自然差异并且维持本国的种类的潜力作为未来工作的本国的种类的自然人口。
