本文回顾了吉林省的各种林业实践活动,重点强调了吉林省丰富的自然多样性和中国乡土物种的巨大潜力。作者认为适应与森林资源开发和生态建设相关的土地管理机构的需求,中国的研究人员应该将研究的重点更多地放在如何开发乡土种的潜力上。外来种的引进和试验应该仅限于严密的科学试验,同时在林业引进外来种之前应该事先与乡土种进行对比,包括潜在的外来侵入种和害虫的问题,以防产生有害的生态后果。作者还强调了保持可育的(例如:基因多样性和繁殖适合度)乡土种自然种群的重要性,因为只有这样才能保护中国珍惜的自然多样性,保持乡土种作为当地森林和生态建设的种源的潜力。参 4。
This paper reviews various forestry practices in Jilin Province, highlighting the rich natural diversity in Jilin Province and the tremendous potential of Chinese native species. The author believes that to meet the needs of land management agencies related to forest resource development and ecological construction, researchers in China should focus more on how to develop the potential of native species. The introduction and testing of exotic species should be limited to rigorous scientific experimentation and should be contrasted with native species before introduction of exotic species, including potential invasive alien species and pests, to prevent harmful ecological consequences. The authors also emphasize the importance of maintaining a natural population of native species that are fertile (eg, genetic diversity and reproductive fitness), as the only way to preserve the natural diversity of China’s treasures and to preserve native species as a local forest and ecological species Potential of the source.
