| Abstract: | The diversity of the forest on low mountains and hills in Northern Jiangsu Province are studied. The results are given below: 1). Species diversity index (SDI), community evenness index (CEO and ecological dominance index (EDI) for mixed forest are 1. 39-2. 40, 0. 56-0. 88 and 0. 15-0. 39 respectively. The mixed forest leads in the order of diversity, followed by oak forest and temperate pines (Pinus densiflora forest). SDI, CEI and EDI for Ptatycladus orientalis forest and Robinia pseudoacacia forest are 0. 07-0. 16, 0. 07-0. 15 and 0. 94-0. 98 respectively, and they rank forth in the order of diversity. 2). Relatively, the biodiversity in the northeastern part of the studied area is greater than that of its northwestern part. |
