黑龙江省种子植物多样性研究

为了有效保护和持续利用生物资源,通过野外调查及资料统计分析,明确黑龙江省种子植物多样性。结果表明,黑龙江省有野生种子植物111科565属1663种,其中中国特有属2属,中国特有种42种,国家珍稀濒危保护植物16种。黑龙江省植物资源丰富,可分为药用、观赏、饲料、食用等12类;按Raunkiaer生活型分类,地面芽植物741种,占总种数的44.56%,其次为隐芽植物;按《中国植被》生活型分类,多年生草本1035种,占总种数的62.24%,一年生草本294种;在水分生态类型中,中生植物1128种,占总种数的67.83%,湿生植物293种,占总种数的17.62%。同时对黑龙江省生物多样性的保护与持续发展对策也进行了探讨。

Study on diversity of seed plants in Heilongjiang Province

In order to effectively protect biological resources and make clear the diversity of seed plants in Heilongjiang Province, according to field investigation and data statistics. The results showed that there were 1 663 species wild seed plants in Heilongjiang Province, belonging to 565 genera and 111 families, among which two genera and 42 species were Chinese endemic, 16 species were rare and endangered plants. They were rich in plant resources which could be divided into 12 classes, such as medicinal, ornamental, feed, edible; on classification of Raunkiaer life style, hemicryptophyte was 741 species, which made up 44.56%, the next was cryptophytes; on classification of Chinese vegetation life style, perennial herb was 1 035 species and made up 62.24%, annual herbaceous was 294 species; the species of mesophyte were the most of ecological type of waterthat took 67.83%and those of hygrophytes took 17.62%. Suggestions and countermeasures for protection and the sustainable development of biodiversity in Heilongjiang Province were put forward.
