黑龙江省林区药用植物资源及其区划

黑龙江省森林面积为1，5771百万公顷，占全省总面积的34.7%。全国森林总面积的12.5%。黑龙江省森林具有丰富的药用植物资源，研究表明，共有药用植物724种，分别隶属于110科，410属，其中商品药植物352种，分别隶属于91科，250属，根据地域分异规律。结合全省气候，土壤，地形，地貌，植被及药用植物生态分布特点，自然植被，植物区系与药用植物生态分布的相关性，将全省森林药用植物资源进行了综合区划，全省共分为2个区，即大，小兴安岭药用植物区和张广才岭药用植物区，进行全省森林药用植物资源区划，对于合理保护和利用林区药用植物资源，发展林区经济具有重要现实意义。

MEDICINAL PLANT RESOURCES OF FOREST REGION IN HEILONGJIANG PROVINCE AND THEIR DISTRICTING

The forest area in Heilongjiang Province is 1,5771 million hm 2, and is 36.8% of the total area of Heilongjiang Province, and 12.5% of the total forest area of China. There is rich medicinal plant resource in the forest. The investigation showed that the number of medicinal plant species is 724,belonging to 110 families, 410 genus, and of the commodity medicinal plant species is 352, belonging to 91 families and 250 genus. The medicinal plant resource is divided into two regions based on endemic segregation regular pattern in the forest region of the province. At present the medicinal plant resource reduced seriously because of over digging and over grazing and the environmental degradation in the forest. Now the number of indangered species of medicinal plant is 8, and 19 species is nearly danger. In order to protect medicinal plant resource 11national and 21 provincial conservation districts were set. At the same time, the plantations of medicinal plants, such as Panax ginseng, Getiana scabra, Astragalus membranaceus, Panax quinquefolium, Acanthopanax senticosus, Schisandra chinensis and so on were built. The development strategies about medicinal plants in Heilongjiang Province is to protect the rare and imminent species, to breed them with advanced bio-techniques, to improve the pharmaceutical technology, and to exploit high-quality products from medicinal plants.
