江苏灌河口湿地景观生态规划:可持续发展的方案

Landscape Eco-planning for Guan River Estuary Wetland in Jiangsu Province: Towards Sustainable Development

灌河是江苏省除长江外唯一的未在入海口建闸的河流,上通盐河、京杭运河和淮河,腹地广大,灌河河口段可满足万吨轮航运条件,有巨大的开发价值。在分析研究灌河口湿地资源、环境与景观生态特征的基础上,利用景观生态学中景观生态规划的方法和原理,提出了建立景观生态保护区,开发河海牧场、生态农业和生态旅游资源,加快中等港口群和临港产业区建设并举的景观生态规划方案,通过灌河口湿地一体化开发、保护和管理的示范作用,带动整个流域的经济与生态环境保护的协调发展。

Occurrence of schools of cetaceans in the Guan River estuary wetland of Jiangsu gave an great and wide impetus to rethink the resources, environment and sustainable development of that region. The Guan River estuary wetland is located on the boundary of Lianyungang and Yancheng in Jiangsu Province. It is rich in natural resources, but constrained by various unfavorable natural conditions and facing human-activity-induced problems, such as bayrnouth bar limitation, poor infrastructure and harbor facilities, environmental quality degradation, lack of rational development plans, and so on. Landscape eco-planning plays a role in the conservation of biodiversity and environmental improvement. It will not only satisfy the natural functions of landscape and human requirements, but also satisfy the future development. As regard to the future model of natural conservation and resources development, the concept, principle, procedures and main model of landscape eco-planning are introduced. This paper makes a comprehensive survey and summary of the landscape ecological characteristics of the Guan River estuary wetland and proposes some corresponding landscape eco-planning approaches towards sustainable development of the area. The project is composed of some landscape ecological protection areas, and a carefully designed ecological agriculture river-marine farm, ecotourism, planning and framework, harbor and industry estate construction along harbor.
