帽儿山实验林场不同森林类型锈菌种类多样性

Diversity of Rust Fungi in Different Forest Types of Mao'er Mountain Experimental Forest Center

对帽儿山实验林场的5种主要的次生林森林群落内的锈菌种类、数量进行调查,经鉴定共发现锈菌13属47种,分析得出林木锈菌多样性指数随着次生林生态环境的恶化和寄生植物多样性指数增高而增高。这也提示人们当林内锈菌多样性指数增高时,说明林内生态环境在恶化,应予以改善、恢复。

The species and their quantities of rust fungi were investigated in the 5 main secondary forests of Mao＇ er mountain experimental forest center,through identification,13 genera and 47 species were found.The results showed that diversity index varied with the ecological environment of secondary forests,it increased along with the increase of parasitic plant diversity index.This also suggested people should improve and recovery forest ecosystem when the index of the rust diversity increased.
