摘要
随着经济发展和人类活动不断增加,自然生态系统受到越来越多的人为扰动,生态分区作为识别各类生态问题及问题溯源的有效工具被各国广泛应用。本研究基于大量的资料调查,在ArcGIS 9.3软件环境下,利用层次分析模型对环渤海近岸和海域的空间数据进行处理与分析,实现了渤海近岸陆域、海域和近岸以外海域的生态分区。并进一步采用环境质量指数法对所划分的7个海区进行了验证,验证结果表明本研究基本合理。研究结果可望为渤海生态系统管理保护提供参考依据。
With the development of economic growth and intensity of human activities,the natural ecological system is more and more disturbed by the human beings,thus eco-regionalizing has been widely recognized as a vital tool for identifying the ecological problems and tracing the source of problems.In this study,extensive data in question was collected and spatial data was processed and analyzed under the ArcGIS environment,thereafter the eco-region pattern for coast of the Bohai Sea Bay Region was delineated using analytic hierarchy process（AHP）.The environmental quality index was further used to verify the eco-region pattern delineated in this study.Hopefully,the findings of this study could provide the scientific basis and reference for ecosystem-based management of the Bohai Sea Bay Region.
