基于生境保护的厦门湾海岸线开发建港生态承载力评价

摘要

生态承载力评价是优化建设发展项目规划方案、促进社会经济与自然生态环境可持续发展的重要参考基准,但目前国内常用的综合性、区域性生态承载力评价技术方法针对性较弱,不适用于评估项目规划区范围内自然资源及生态环境系统对特定类型工程建设的可持续承载力.以厦门湾为例,综合利用遥感(RS)与地理信息系统(GIS)技术,基于海岸带重要物种生境保护,运用生态适宜性评价原理,结合海岸线建港开发常规约束限制条件构建评价指标体系,探索海岸线建港开发生态承载力评价技术,以提升评价成果调整优化项目规划方案的技术支撑能力,促进项目规划生态承载力评价技术方法革新.%The evaluation of ecological carrying capacity is the important reference for optimizing the project plans and promoting the sustainable development of socio-economy and natural environment.However most of the available evaluation methods of ecological carrying capacity are incompetent in project pertinence.The methods are basically used to study the comprehensive and regional resource and environmental problems,but not suitable for assessing the sustainable carrying capacity of natural resource and eco-environment systems for specific types of project construction within the planning area.Taking Xiamen Bay as an example,the RS and GIS technologies were applied and the principle of ecological suitability evaluation used to constitute the evaluation index system and explore the ecological capacity evaluation technique for the coastal port development,based on coastline habitat conservation of important species and in combination of the constraint conditions for the development.The research can enhance the technical supports ability of the evaluation results in improving the project schemes,and promote to reform the ecological capacity evaluation technologies for project plans.
