摘要
为了进一步了解物种受威胁的情况和发展，以加强物种保护工作，世界保护联盟制定了一个新的物种受威胁分类系统草案，把物种受威胁的程度分为９个级别，即绝灭种、野生状态下的绝灭种、极危种、濒危种、渐危种、敏感种、安全的／危险性小的种、不充分了解的种和未估价的种。本文对这个分类系统草案作了简略的评介。
For further understanding on threatened states of biological species and their development,the IUCN draft of new threatened category system was formulated.The following 9 levels were inclued in the new system:Extinct(EX),Extinct in the Wild(EW),Critical(CR),Endangered(EN) Vulnerable(VU),Susceptible(SU),Safe/Low Risk(S/LR),Insufficiently Known(IK)and Not Evaluated(NE).Fhis paper simply makes introduction and review on this system for reference.
