河北省海洋可持续发展动态评价

以河北省海洋可持续发展为研究对象，采用国内外主流的指标体系评价法，在构建由1个总系统、2个分系统、5个子系统、9个亚子系统和27个指标构成的指标体系基础上，采用由指标层评价法、赋权和系统综合评价法、可持续发展水平判别准则和协调度评价法构成的评价方法体系，开展了1995-2008年河北省海洋可持续发展动态评价。结果表明，评价期内经济发展水平快速提升，结构进一步优化，海洋资源利用效率各项指标持续改善，资源利用的经济效率普遍提高。海洋生物资源密度和滩涂资源密度等重要海洋资源质量状况持续退化。海洋生态除了生物健康指数和风暴潮损失两项指标呈波动性改善外，其他各项指标整体恶化，单位岸线人海水量和赤潮发生频次恶化速率最快，滨海湿地森林覆盖率和单位岸线海水入侵面积恶化速率次之，侵蚀岸线比例恶化速率最慢。总之，评价期内河北省海洋开发处在以资源环境为代价获得经济增长的弱不可持续发展状态，但环境与发展的协调度持续好转，即单位经济发展的环境代价持续减小。

Dynamic Evaluation of Sustainable Development of Ocean in Hebei Province

The study is conducted by taking the sustainable marine development of Hebei Province as the study object and using the dynamic evaluation method that is the mainstream way at home and abroad for evaluation.After establishing the index system with a total system,2 subordinate systems,5 subsystems and 27 evaluation indexes,the evaluation method system composed of index layer evaluation method,empowerment,comprehensive evaluation method,the criteria for the level of sustainable development and coordination degree evaluation method is adopted to search the dynamic evaluation of sustainable development of Hebei ocean in 1995-2008.Results show that during the period of evaluation,the level of economic development was increasingly promoted and the structure of economy was further optimized.Every index of use efficiency of marine resources continued to improve.The important qualities of marine resources continued to degrade,such as the densities of marine biological resources and tideland resources.In addition to the biological health index and storm loss index that were improved in a fluctuant way,other marine ecological indexes were all worsen.The sea water per unit coastline and the occurrence frequency of red tide decreased fastest,followed by coastal wetland forest coverage and the seawater intrusion area per unit coastline.The proportion of eroded coastline decreased slowest.In short,during the period of evaluation,the ocean development of Hebei Province was in the weak unsustainable development state at which the economic growth is the cost of resources and environment.However,the coordination degree of environment and development was increasingly improved,i.e.,the environmental cost for unit economic development decreased continuingly.
