摘要
为了解天津市的生态安全状况和城市发展的潜力。本文结合野外调查和统计数据,建立了天津市生态脆弱性评价指标体系。并应用层次分析法,对指标体系进行了量化处理,继而全面评价了天津市的生态脆弱性。得出了天津市由于水资源的过度消耗,造成了由东部沿海地区向内陆生态环境脆弱性逐渐变化的格局。其结果对天津市的水资源的合理利用与保护具有指导意义。
In order to know the status of ecological safety and potential of urban development of Tianjin,ecological fragility evaluation index system was established through field investigation and the statistical analysis.Hierarchic analysis was applied to quantitatively process the index system for then evaluate the ecological fragility of Tianjing.The result showed that as a result of excessive consumption of water resources,the ecological environment weakens gradually from the eastern coastal area to the interior,which provides a significant guidance for rational utilization of water resources.
