海平面上升对广东近岸海域环境影响研究

The Study on Impacts of Sea Level Elevation on the Offshore Marine Areas Environment of Guangdong

全球气候变暖会引起海平面上升,已有研究表明,广东沿海海平面上升量最大,上升速度为2.19 mm/a。本文根据张锦文对广东沿海的海平面上升估计值,研究了广东沿海到2030年、2050年和2100年时由海平面上升造成的海岸滨线后退和海岸面积损失的影响,并进一步分析了海平面上升对广东近岸海域红树林、海草和湿地生态系的影响。

Global warming cause sea level elevation, the study of existing indicated sea level elevation of the offshore marine areas of Guangdong is the most, the rate is 2. 19mm/a. Based on sea level elevation of the offshore marine areas of Guangdong was estimated by Zhang Jinwen, this paper analyzes the impacts of sea level elevation on the offshore marine areas backing off of coast shoreline and the losing of coast area of Guangdong, and the impacts of sea level elevation on the offshore marine areas ecosystem of mangrove, seaweed and wetland of Guangdong unto 2030,2050 and 2100.
