Estimation Method for Spatial Capacity of Sea Areas Reclamation

Abstract

This paper suggest 5m depth line is suitable depth for sea areas reclamation based on study of sea areas reclamation investing and established estimationmethods for spatial resource capacity of sea areas reclamation. Then Liaoning province in China was chose as a case to estimateitssea areas reclamation capacity. The result shown as follows: Depth of sea areas near the coastline in Liaoning province is smaller than 5m in most sea fields. Length of coast with under water slope angle less than 1°is 1988.77km and account for 52.25% coast of Liaoning province. The total areas of sea reclamation capacity is 211714.06hm2.Its distributes mainly in Dalian sea areas, Jinzhou sea areas and Yingkou sea areas with percentage of 47.19%，18.78% and 14.53%,respectively.

Remote sensing monitoring and analysis of coastal infrastructures’ water environment effects in the Guangdong-Hong Kong-Macao greater Bay Area

“…Some sea area will be occupied during the progress of coastal transportation infrastructure construction such as land reclaiming. Therefore, the original water ecology will be destroyed [5,6,7]. At the same time, the construction of coastal transportation facilities may greatly affect the original hydrodynamic environment, leading to the weakening of the self-purification capacity of the coastal waters and some serious water pollution [7,8].…”

At the same time, the construction of coastal transportation facilities may greatly affect the original hydrodynamic environment, leading to the weakening of the self-purification capacity of the coastal waters and some serious water pollution [7,8]. For example, the construction of the Jiaozhou Bay Bridge has caused tide levels, tidal currents, and tidal absorption [1].…”
