我国沿海地区地势低洼，生态脆弱敏感，是自然灾害的高发区。21世纪全球海平面上升和区域地面沉降叠加的结果是全球相对海平面上升的加速趋势。同时，水库的修建也将加剧土地淹没、暴雨洪涝灾害和水资源短缺，进而影响城市的承受能力、建筑安全和生态资源。根据可持续发展理论，我国沿海地区只有实施控制温室气体排放、地下水优化开采和人工回灌、地面沉降的系统治理、提高潮汐防洪工程的设计标准，提高城市抗灾能力，研究城市遥感减灾战略与政策，建立城市遥感灾害预测预警机制。
The Chinese coastal regions are the high risk areas of natural disasters for their low land and weak and sensitive eco-evironment. The relative sea-level rising (RSLR), resulting from the piling of global sea-level rising and regional land subsidence, is to speed up in the 21st century. Certainly the RSLR will exacerbate the land submerging, the disaster from storm-tide and flood- waterlogging and the water shortage, and then affect urban withstanding function, construction safety and eco-resources. According to sustainable development theory, the sustainable utilization of resources and environment and sustainable development of economy and society can both be effectively achieved in coastal regions of China in the 21st century only by the implementation of controlling discharge of greenhouse gas, optimal exploitation of and artificial recharge of groundwater, systematic control of land subsidence, higher design standards for tide and flood control engineering, improving urban anti-disaster ability, a study on strategy and policy for RSLR and establishment of forecast and pre-warning institution.
