The coastal geological environment and blue-green economic chain in China

Abstract

The characteristics of coastal zones are controlled by the geological structure and properties of rock and soil mass, and accordingly they can be classified into several categories. In this paper, six important problems confronted in coastal geological environment were discussed: (1) earthquake and tsunami; (2) seawater invasion; (3) coast erosion and sedimentation; (4) coastal subsidence; (5) climate—geological disaster chain control; and (6) sea level change. In the West Coast Economic Zone with the core being Fujian Province, China, some coastal cities, such as Fuzhou, Xiamen, Quanzhou, are affected by the Minjiang, Jiulongjiang and Jinjiang rivers. This paper discusses the geological environment of these cities, and the significant connection with the river ecology. A conceptual framework was proposed for developing a sustainable ecological river and a water-front city with ecological civilization.
