摘要
基于遥感信息获取技术,以上海南汇东滩为例,建立了海岸带生态环境基础质量遥感评价指标体系,对城市生态环境遥感评价模型增加海洋专家打分权重进行改进,并开发海岸带生态环境评价的信息管理工具,实现了研究区生态环境遥感多个年份的定量评价,分析研究区生态环境质量变化原因,为构建更好的海岸带管理决策支持系统,从而更好地管理海岸带资源,确保海岸带可持续发展的能力提供技术支持。
The interaction area of sea and land,the coastal zone is of ecological fragility.With the fast development of economy and a substantial increase in the population,human impacts more and more on the coastal ecology.It will become a focus of society that how to evaluate the environment impacts produced by the coastal resources exploitation and infrastructure construction.Based on the remote sensing information extraction technique,the assessment indexes system of the eco-environmental basic quality in coastal zone was established,according to the experts grading,the marine expert weight factors were decided with the Delphi technique.The geophysical information system to evaluate the coastal zone environment was built.It was very convenient to assessment the time-space distribution and variation law in the coastal zone studied.The method is useful to build the coastal zone management decision system,and provided the technical support for the sustainable development in coastal zone and government better to manage the coastal zone resources.
