生物多样性关系到资源的开发和管理及环境的保护,是当前国际间十分热门的研究课题。生物多样性包括三个层次:生态系统多样性,物种多样性和遗传多样性。一个物种的消失,首先就是遗传多样性的降低,一个物种或群体的繁盛则常伴以遗传多样性的增加和稳定,而一个物种的兴衰又常决定整个群落生态系的演替行为。因此,研究生物遗传多样性无论对于保护还是开发并永续利用与未来农业、医学和工业发展密切相关的生命资源都是十分重要的。
Biodiversity is related to the development and management of resources and the protection of the environment. It is a very hot research subject in the world at present. Biodiversity includes three levels: ecosystem diversity, species diversity and genetic diversity. The disappearance of a species begins with a reduction in genetic diversity. The prosperity of one species or group is often accompanied by the increase and stabilization of genetic diversity, and the rise and fall of one species often determines the succession behavior of the entire community ecosystem. Therefore, studying biological genetic diversity is of great importance for the protection or development and sustainable use of living resources closely related to the future development of agriculture, medicine and industry.
