Abstract:The woody flora, forest types and dynamics as well as the climate and soil characteristics in Nanking were synthesized. The 282 woody species, belonging to 143 genera and 53 families, were recorded, among which there were only 5 evergreen broad-leaved trees and 11 evergreen broad-leaved shrubs. The forest could be classified into 9 formations, i. e. ,Form. Liquidambar formosana, Form. Quercus variabilis, Form. Q. fabri, Form. Q. acutissima, Form. Q. dalbergia, Form. Robinia pseudoacacia, Form. Pteroceltis tatarinowii, Form. Pinus massoniana and Form. Pinus thunbergii. The analysis of the vegetation dynamic showed that the forest in Lin-Guo-Shi (Temple of the spirit Valley)developed toward the Liquidambar formosana-Quercus fabri-Q. variabilis forest; the forest in Qixia Mountain, toward the L. formasana-Q. variabilis Tilia forest; while the forest in Lanya Mountain, toward the Pteroceltis-Zelkova-Platycarya-Acer-Paliurus forest.It is much more colder in Winter in Nanking than in Hanzhong and Ankang, the northernmost distribution area of the evergreen and deciduous broad-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.
