秦岭森林锈菌区系

从1983～1995年，作者在秦岭地区采集了以树木锈菌为主的森林植物锈菌30属90余种。对这些锈菌的生态和生物地理分析表明：秦岭锈菌以温带型占明显优势（65％），且多分布于海拔1300～2800m的中山针阔叶林带中。该地区锈菌区系的地理成分以东亚成分为主，尤以中国-日本成分为主；欧亚-北美成分和旧世界温带成分在秦岭占有相当比例（约30％）。古热带成分等其它地理成分的锈菌也汇集于此。秦岭地区锈菌区系起源古老。

RUST FLORA OF THE FOREST OF QINLING MOUNTAINS

More than 90 species of rust fingi belonging to 30 genera were collected by the authors from the forest of Qinling Mountains in 1983 ~ 1995.Ecological and biogeographical analysis of these rusts revealed that the rusts of temperate zone were predominant, amounting to 65% of the total known genera,distributing mainly in coniferous and broad-leaved mixed forests in alt.1300 ~ 2800m. East Asian element shares the highest percentage, amounting to more than 30% of the total number of known species. Eurasian - North Ainerican element and paleotemperate element account for less than 30% of the total numberof species. In addition, there are also some paleotropical species, accounting for 10%of the total. The rust flora belongs to East Asian rust flora with ancient origin.
