摘要：Longxi-Hongkou National Natural Reserve is famous for its high diversity in wild plant resources,which are divided into 5 groups,and 10 smaller ones respectively according to their usage and chemical composition on the basis of the field investigation and checking relative literature.There are 221 species of medicinal plants,including lots of traditonal Chinese medicines,medicinal herbs and new drugs,407 species of horticulture plants,102 species of edible plants,being inclusive of 62 species of edible fruit plants and 40 species of vegetable plants,61 species of fragrant plants,and also 684 species of other plants,such as fibre plants（90 species）,oil plants（107 species）,starch plants（42 species）,tannic plants（32 species）,timber plants（111 species） and forage plants（302 species）.High plant diversity with low deposits and having satisfactory variety of plants resources with huge potentiality for development are characteristic of wild plant resources in the reserve.The contradiction between scientific development and biological diversity conversation should be resolved in accordance with the principle of sustainable utilization and the development of plant resources.%龙溪—虹口国家级自然保护区具有非常丰富的野生资源植物。作者通过野外实地调查及查阅相关文献资料,将保护区内的资源植物根据资源植物的用途及化学成份,分为5大类,11小类。统计表明,保护区共有药用植物221种,园林植物407种,食用植物约102种,包括果用类型62种、蔬菜植物资源约40种,芳香植物61种,其他植物684种,包括纤维植物90种、油脂植物107种、淀粉植物42种、单宁植物32种、用材植物111种、饲料植物302种。保护区资源植物具有种类丰富、蓄积量小、品类齐全、开发潜力大的特点。在开发利用的同时,应本着可持续利用的原则,解决合理开发利用与生物多样性保护之间的矛盾。
