从遥感图像看人文工程对港口水文地质环境的影响——以连云港拦海大坝为例

THE INFLUENCE OF MAN-MADE PROJECTS ON HYDROLOGICAL AND GEOLOGICAL ENVIRONMENTS VIEWED FROM REMOTE SENSING IMAGES: EXEMPLIFIED BY THE SEA DAM IN LIANYUNGANG

通过多时相卫星遥感图像对江苏省连云港拦海大坝分析研究后认为 ,拦海大坝在为地方经济作出贡献的同时 ,也彻底改变了港口的水文地质环境 ,改变了近岸海流、泥沙流运移路径和对港池的冲刷作用 ,引起港池淤积加剧和周边水文地质环境向不良方向发展 ,并提出了治理对策与建议。

Human beings should get along well with the nature and must not violate the natural regularities. Based on studying satellite images of the sea dam of various times in Lianyungang, the authors consider that, while contributing to the local economic development, the dam totally changed the hydrological and geological environments of the harbor. It changed the sea currents near the shore, the transporting paths of the silts, and the erosions of the harbor, which caused the deterioration of the hydrological and geological environments. As a remedy, the authors put forward some proposals for solving these problems.
