崇南水陆交错带景观整体适应性评价与提升

Assessment and Promotion Strategy on Landscape Holistic Adaptation of Land-Water Ecotone in Southern Chongming,Shanghai

水陆交错带存在自然和人文要素复合影响作用,其景观系统整体适应能力亟需提升。以崇明南部水陆交错带为研究对象,基于景观系统本底评价,借鉴景观特征评价(LCA)方法,探讨岛屿水陆交错景观整体适应性评价方法。从自然资源保护重要程度、土地资源利用适宜状况、环境安全压力显著特性3个子目标层,构建12个指标因子的评价体系;并进行要素层面和目标层面的适应性评价分析;确定研究区6类适应性特征分区,提出其景观资源适应性发展提升策略。研究为水陆交错带景观系统整合发展提供保护性开发的评价方法和决策支持路径。

The land-water ecotone is under the influence by the combinatory of natural and human factors, and the adaptability development of its landscape system urgently needs scientific and rational assessment tool. This paper explored the holistic adaptation assessment method of the land-water ecotone in southern Chongming island, based on the landscape physical characteristics analysis from baseline evaluation, and the characteristic zoning from the Landscape Character Assessment tool(LCA). The study formed the adaptation assessment system from three sub-target levels: the importance status of natural resources protection, the suitable situation of land resources utilization and the significant characteristics of environmental security pressures. The assessment system was constructed by 12 selecting indicators, and the adaptation assessment analysis at the factors level and target level was carried out. Six type of adaptation zonings were formed and the promotion strategies for the holistic adaptation of landscape resources were put forward. The research provides the evaluation method and decision support path for the integrated development of land-water Ecotone Landscape system.
