沿海滩涂开发利用综合效益评价

Comprehensive Benefit of Tidal Flat Development and Utilization

为提高我国沿海滩涂的开发利用水平,促进经济社会和生态环境的协调可持续发展,文章在梳理相关定义和研究的基础上,探索沿海滩涂开发利用综合效益评价。研究结果表明:针对具有开发利用价值的潮间带和潮下带,其开发利用的综合效益为从全社会角度出发,以多项指标体现的,可识别和可量化的全部效益的总和;遵循科学性、系统性和统筹性原则,从资源利用、生态环境、经济增长和社会发展4个方面,选取自然岸线保有率等28项指标,建立评价指标体系,并采用递阶多层次综合评价模型计算综合评价值,从而评价沿海滩涂开发利用综合效益。

In order to improve the development and utilization level of tidal flat in China and promote the coordinated and sustainable development of economy, society and ecological environment,this paper explored the comprehensive benefit evaluation on the development and utilization of tidal flat based on the relevant definitions and research.The results showed that the comprehensive benefits of development and utilization of the intertidal zone and the subtidal zone with development and utilization value were the sum of all the identifiable and quantifiable benefits reflected from multiple indicators of the whole society.The evaluation was followed by the principles of science,system and co-ordination.From the 4 aspects of resource utilization,ecological environment,economic growth and social development,28 indicators were selected such as natural shoreline retention rate and so on,to establish an evaluation index system,and adopt hierarchical multi-level comprehensive evaluation.The model calculated the comprehensive evaluation value to evaluate the comprehensive benefits of development and utilization along tidal flat.
