摘要
研究发现北桑寄生的生存繁衍需要一定规模的寄生群体、特定的种子传播媒介、良好的生态环境 ,正是这些特殊要求 ,限制了它的繁衍和分布。在生态环境日趋恶化的形势下 ,其种群已十分脆弱 ,若不加强保护 。
The studies of Loranthus tanakae Franch. et Savat in Mountain Yangtian shows that the existence of the species needs some specific conditions,such as an enough large population,a specific seeds speeding medium and a suitable natural ecological condition.These conditions limit the reproduction and distribution of Loranthus tana kae. Now,the distribution area of Loranthus tanakae and the population face the bad environment and heavy existence pressure. Loranthus tanakae Franch.et Savat in this area would face the risk of extinction without protection.
