摘　　要：简述了进行化学品植物毒性评价和鉴别的种类、方法和意义,强调有毒化学品对维管束植物的毒性和严重后果,呼吁加强我国在这方面的研究并尽快建立相应的评价方法和标准,以完善我国化学品生物毒性鉴别和评价方法及标准体系,为保护环境质量,提高人们生活水平,维护我国的生态安全服务。虽然过去由于我国工业化程度较低而没有出现什么问题,但现在必须及时给予重视,防患未然,以免重走西方发达国家的弯路。The significance,methods and types of bioassay and phytotoxicity assessment of toxic chemicals are reviewed mainly due to phytoassessment studies having become more of an integral component of environmental monitoring and ecological risk assessment since the early 1990s. It is emphasized that the phytotoxicity and effects of the toxic chemicals on vascular plants are hazardous to their health growth and existing. The consequence will be dangerous for ecosystems including the creature and the man. Appealing to increase the research of this aspect in our country so that the methods using vascular plants for bioassay and phytotoxicity assessment of the toxic compounds can be developed and the standards can be established as soon as possible. This will make our system for toxicity assessment be more all-around in protecting our environment,assuring the ecological security,bettering the life quality of people. Based on which it was drawn that there were no catastrophic environmental incident ouuring in our country due to the poor industrialization in the past,but now we must give great attention to it to avail repeating the crooked way in dealing with environmental problems. Thus,in the status of current economic integrity of global,the strict standardized methods of plant toxicity tests,bioassay and the regulations under the environmental laws of our country will be more propitious to protect the environment and warrant the ecological safety.
