摘要
杂草资源的特点表现为：各地杂草区系具相对的一致性，杂草抗逆性强、适应性灵活、生物量丰富，具有被持续利用的优势；杂草资源易于被人们采集。杂草资源在科学及生产实践中有多种用途。在植物资源研究中，也不应忽视杂草种质资源保护的问题。生物多样性研究也应包括对杂草的研究。
eed flora in different areas are similar in their elements, with their excellent.tollerance and adaptation, and weed biomasses are usually sufficient. Besides,weed resources are liable to be obtained because of their distinctive characteristics.Analysis showed that it is important to study weed resources in theory and practice.Like other plant resources, some agrestal weeds may also be in an endangered state.The study of biodiversity should not exclude weed resources.
