| 摘 要： | 怒江峡谷特殊的自然地理环境和立体气候,孕育出种类丰富的植物资源,新老、珍稀、孑遗和特有种兼备。有维管束植物185科878属3138种(包括亚种和变种),其中蕨类植物41科101属374种,裸子植物5科12属22种,被子植物139科765属2742种。峡谷区科属种分类分别占云南同类植物的56.74％、40.46％和20.79％,占横断山区的84.47％、59.95％和36.66％;植物区系成分复杂多样,各类热带分布属(不含世界分布,下同)352个,占峡谷区总属数的45.30％;各类温带分布属346个,占峡谷区总属数的44.53％;地中海或泛地中海分布仅16属,占峡谷总属数的2.05％;中国特有属17个,占峡谷区总属数的2.18％。近期有开发前景的植物资源种类多,且门类齐全,是当地各民族脱贫致富,建设家乡的宝贵财富。立足植物资源,面向市场,以科学技术为先导,大力发展名特中药材、多维果类、油料植物、花卉和食用菌等,形成名、特产品,参加国内外市场竞争。建议成立生物资源开发领导机构,建立生物产品生产基地和加工工业,进行集约化生产,重视和加强科学技术和教育投入,制订有关生物资源开发的优惠或特殊政策。

| Abstract: | Because of the peculiar physiographic enviroment and the monsoon climate, the plant resources are much abundant, ancient or new, precious and rare, survival and endemic Species of plant all can be easily found in the Nujiang canyon area, yunnan. There are 3138 species (including subspecies and varieties) of vascular plants, belonging to 878 genera, 185 families, which take 20.79%, 40.46% and 56.74% of that of the province, take 36.66%, 59.9% and 84.47% of that of the Hengduan Mountain Region, among which there are 374 species of pteridophytes, belonging to 101 genera, 41 families, 22 species of gymnosperms, belonging to 12 genera, 5 families, and 2742 species of angiosperms, belonging to 765 genera and 139 families. The floristic elements include 352 genera of tropical distribution (exel. world distribution), which accounts for 45.30% of the whole genera of the area, 346 genera of temperate distribution, accounting for 44.53% of the whole genera of the canyon, and only 16 genera of paleo-or holo-Mediterranean distributions. Multifarious plant resources can be developed with a good prospects recently. These resources are valuable wealth and advantages for the local residents to be rich, taking leave of poor conditions, and to construct their hometown. The author suggests to face the markets based on the plant respurces with recent development prospects, to develop economic forests, peculiar Chinese medical plants, multivitamin fruits, oil plants, flowers and edible fungi, to form famous and particular plant products then taking part in the competition of the domestic and international markets, under the guidance of science and technology. In order to turn the advantages of plant resources into the ones of economy rapidly, the author also proposes to establish a leading institution of developmental group of biological resources, to set up production bases and processing industry for the plant products, conduct comprehensive productions, pay great attentions to scientific, technical amd educational investments, carry out special policies. |
