| 摘 要： | 徐连过渡带位于江苏省北部，地当南北要冲，为一典型的生态过渡带；低山丘陵生态环境遭到严重破坏，生态系统的恢复与重建任重道远。基于10个样地4650m^2的野外调查资料，建立了徐连过渡带低山丘陵森林植被分类系统，包括2个植被型组、3个植被型、3个植被亚型、6个群系组、12个群系。根据建群种与光照强度的关系，分析了12个森林植被群系间的演替关系，构建了徐连过渡带低山丘陵森林植被次生演替模式。以次生演替模式为指导，论述了徐连过渡带低山丘陵生态恢复重建策略。

| Abstract: | Xu(Xuzhou)-Lian(Lianyungang) Ecotone, located in the north of Jiangsu Province, is militarily a very important region in the eastern China. Its ecological environment has been damaged severely, and the burden of ecological restoration and reconstruction is heavy. Based upon the field survey material of 10 plots(4 650 m~2), the classification system of the forest vegetation on the low mountains and hills in Xu-Lian Ecotone is established, including 2 vegetation type groups, 3 vegetation types, 3 vegetation subtypes, 6 formation groups and 12 formations(i.e., Pinus densiflora forest, Pinus thunbergii forest, Platycladus orientalis forest, Robinia pseudoacacia forest, Pistacia chinensis+Dalbergia hupeana forest, Pteroceltis tatarinowii forest, Celtis bungeana forest, Carpinis turczaninowii forest, Quercus acutissima forest, Quercus variabilis forest, Quercus fabri forest and Quercus variabilis+Machilus thunbergii forest). According to the effects of light intensity on forest edificators , the successional relationships among the 12 formations are analyzed, and the secondary succession model of the forest vegetation of the low mountains and hills in Xu-Lian Ecotone is built. Guided by the model, its strategies of ecological restoration and rehabilitation are discussed. |
