【Abstract】 The woody flora. forest types and dynamics as well as the climate and soil characteristics in Nanking were synthesized. The 282 woody species. belo- nging to 143 genera and 53 families. were recorde. among which there wereonly 5 evergreen broad- leaved trees and 1 1 evergreen broad- leavcd shrubs. The forest could be classified into 9 formations. i.e.,Form. Liquidambar for- mosana. Form. guercus variabilis Form. Q.fabri. Form. Q. acutissima. Form. Q. d- albergia. Form. Robinia pscudoacacia. Form. Pteroceltis tatarinowii. Form. Pinusmassoniana and Form. Pinus thunbergii.The analysis of the vegetation dynam- ic showed that the forest in Lin- Guo- Shi(Temple of the spirit Valley) devc- loned toward the Liquidambar jormosana- Quercus jabri- Q. variabilis forest;the jorest. in Qixia Mountain. toward the L. lormasana-Q. variabilis Tilia fo- rest. while the forest in Lanva Mountain. toward the Pteroceltis- Zelkova-plat-ycarya- Acer- paliurus forest. It is much more colder in Winter in Nanking than in Hanzhong and A- nkang. the northernmost distribution area of the evergreen and deciduous bro-AD-leaved mixed forest.The low temperature in Winter could be the main factor limiting the growth of the evergreen broad-leaved trees in Nanjing. The present zonal vegetation in Nanjing should belong to the deciduous broad- leaved forest.更多还原
