据1995年4月《中国测绘报》报导,中国沿海海平面倾斜特征现已探明,整个海平面倾斜为南高北低,东高西低,南北最大高差为58cm,东西最大高差为70cm。根据沿海各地面沉降区的沉降率及沿岸相应的海平面上升值,预测了中国沿海各沉降区相对于海平面到2030年可能上升最大值和最小值,整个沿海地区将有3～4万km~2的土地可能因海平面上升致灾,有关部门应及早采取减灾防灾对策。笔者就以上研究成果信息和已有资料进行分析,我国大陆
According to the April 1995 report of China’s Survey and Mapping, the incline of the sea level in China’s coastal areas has been proven. The entire sea level is inclined south to north and north and low in the east and west. The maximum elevation difference between the north and south is 58 cm. The maximum elevation difference between east and west is 70cm. According to the sedimentation rate of the subsidence areas along the coast and the corresponding sea level rise along the coast, the maximum and minimum values of the possible rising of each subsidence area in China’s coastal area from 2030 to the sea level are predicted, and the total coastal areas will have 40,000 km ~ 2 land may be caused due to sea level rise, the relevant departments should take disaster prevention and mitigation measures as soon as possible. The author of the above research results and information has been analyzed, our country
