摘　　要：对苏北低山丘陵区森林群落次生演替的特征以及空间变化进行了系统研究。结果表明，杂木林多样性最高，物种多样性指数（SD，）1．52～2．39，群落均匀度指数（CEI）0.55～0．89，生态优势度指数（EDI）0.16～0．40；刺槐林多样性最低，SD，0．07～0．17，CEI0．08～0．12，ED10．92～0．97；栎类林和温性松林的多样性分居2、3位。相对而言，苏北东北部低山丘陵区生物多样性较西北部低山丘陵区高。The features of forest community secondary succession were studied as well as spatial variation. The results showed that the highest diversity in forests w-as shaw, whose species diversity index （SDI） was l. 52 - 2.39, index of community evenness （CEI） 0. 55 - 0.89, ecological dominance index （ED1） 0.16 - 0.40 ; Robinia pseudoacaciu had the lowest diversity, SDI 0. 07 - 0.17, CE10. 08 - 0.12, EDI 0. 92 -0.97; Quercus forest and temperate pine forest had the second and the third place in diversity respectively. Relatively speaking, the biodiversity in north-eastern low mountains and hills of north Jiangsu was higher than that in north-western low mountains and hills.
