From the understanding of the conceptual framework for natural vulnerability , the paper analyzes with deep insight into the impacting factors of the natural - system to sea - level change , on the one hand , the coast would be susceptibility to the changes including the short - term sea - level changes such as tide , storm tide , el nino and the long - term sea - level rise . the overlap of this two changes would increase the coastal natural - system vulnerability 文章從海岸自然脆弱性概念框架出發,深入分析了海岸自然脆弱性的影響因素:一方面海岸自然體系對海平面變化具有“敏感性” ,海平面變化包括短期的海面波動,如潮汐、風暴潮、厄爾尼諾等,還包括長期的海平面上升,海平面上升和短期海面變化疊加將加劇海岸帶的“敏感性” 。

The main process of regional ecological risk assessment includes 5 stages : regional analysis , risk receptor selection , risk sources analysis , exposure and hazard analysis , and integrated risk assessment . arming at flood , drought , storm tide , petroleum pollution accident and flow breaking in the lower huanghe river , the probability and distribution of each kind of risk sources are evaluated . the authors bring forward indexes and formulas to measure hazarded degree and risk value of ecosystem . by using remote sensing data , historic record , survey data and by means of geographical information system , regional ecological risk assessment is finished . on the basis of assessment result , the environmental risk management countermeasure of the huanghe river delta is advanced 以黃河三角洲為例進行了區域生態風險評價理論和方法的探討。針對黃河三角洲主要生態風險源洪澇干旱風暴潮災害油田污染事故以及黃河斷流的概率進行了分級評價并提出度量生態損失與生態風險的指標和公式,分析了風險源的危害作用運用遙感資料歷史記錄調查數據和地理信息系統gis技術,完成了區域生態風險綜合評價在此基礎上提出黃河三角洲的區域生態風險管理對策。
