【摘要】 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。更多还原

【Abstract】 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.更多还原
