Abstract: In this paper, woody floras, forest types, and characteristics of the climate and soils between Nanjing and Lianyungang were comparatively analysed. The main conclusions were as follows: (1)there were woody plants of 53 families (F), 143 genera (G), 282 species (S) in Nanjing and 50F, 114G, 191 spp in Lianyungang,among which 49F, 106G, 150 stop were found in both areas. The dominent species of the two forests were all deciduous;(2) the forest in Nanjing could be devided into 9 formations and that in Lianyungang into 7 formations. Formation Liquidambar formosana, Formation Quercus variabilis and Formation Quercus acutissima occured in the two areas. The types that didn't exist in Nanjing or in Lianyungang were almost all cultivated ones, such as Formation Pinus massoniana, Formation Pinus thunbergii, Formation Catalpa bungei, etc; (3) winter in Nanjing and Lianyungang was much colder than that in Hanzhong and Ankang which lie on the northern boundary of the evergreen and deciduous broad-leaved mited forest belt. Lower winter temperature may prevent evergreen broad-leaved trees from growing in these two regions. For above conclusions,the broad-leaved forest in Nanjing could be considered as a type of deciduous forest.

Key words: Pinus koraiensisdominated broad-leaved mixed forest, forest gap size, soil water content, geostatistics, spatial heterogeneity.
