摘要
生态区划是有效利用自然资源、保护生态环境的基础.海岸带作为全球生态环境最脆弱、最敏感的区域之一,生态区划能更好地促进海岸带资源环境的可持续发展,可为管理者和决策者提供理论依据.从生态环境的角度出发,综合分析了渤海海岸带的生态环境特征及其区域分异规律,并建立了生态分区指标体系和命名系统.以地理信息系统为基本工具,建立了气候、地形、土壤、水系和土地利用等数据库,运用GIS技术进行生态要素的空间分析,完成了渤海海岸带生态区划,全区共分为4个生态区和15个生态亚区.最后分析了每个生态区的生态环境问题,并提出了相应的保护对策.
Ecological regionalization is the foundation of effective utilization of nature resources and protection of the environment. The coastal zone is one of the most vulnerable and sensitive environmental systems in the world. Ecological regionalization for coastal zone can improve the sustainable development of the coastal environment and resource, and afford theoretical foundation for governors and decision-makers. Based on the analysis of the ecological characteristic in Bohai coastal zone, indicator system and nomenclature of the ecological regionalization for the zone were put forward. With the support of GIS technique, the superposition of the main factors including topography, landform, climate, soil, water system and land use, etc. , was done. Four eco-environment regions and fifteen sub eco-environment regions were divided in Bohai coastal zone. In the end, the ecological problems of each eco-region were analyzed, and some protective measures were put forward.
