我国东北部寒冷地区野生果树植物优先保护评价

在对以长白山区为主的农业野生植物资源综合调查时发现,野生果树资源生存现状岌岌可危,数量急剧减少。因此,采用珍稀植物优先保护分级研究的方法,构建了以蕴藏系数、保护缓急程度等7项指标定量评价植物优先保护指标体系,评价了分布在我国东北部寒冷地区的野生果树资源,为其资源的保护和开发利用提供参考依据。通过对12科、33属、49种的评价指出,有6科、9属、11种急需保护。

Evaluation System of the Priority Conservation of the Wild Fruit Plants in Cold Area of Northeastern China

Investigation of agronomic wild species mainly in Changbai Moutain area indicated the worrying state for wild fruit tree resources,with a sharp decrease in number.An quantitative evaluation system of the priority conservation of the wild fruit plants was established,by using the method of priority conservation grading index of the rare plants.It contained seven indexes such as storage coefficient,protection emergency degree etc..The quantitative evaluation system was applied to evaluate the wild fruit tree resources in cold area of northeastern China.It could provide a reference for the potection and development of the resources.12 families,33 genera and 49 species were evaluated.The results showed that 6 families,9 genera and 11 species need to be protected urgently.
