發(fā)布時(shí)間：2018-09-07 12:41
【摘要】：通過(guò)天津中心漁港、寧德核電廠、珠海貨煤碼頭圍填前后SPOT-5/6遙感影像的信息提取和比較,分析3個(gè)工程海域圍填和岸線利用的差異。研究表明:天津中心漁港以垂岸向海為主的建設(shè)形態(tài)更有利于岸線的節(jié)約利用,其圍填效率1.46km~2/km、岸線增長(zhǎng)1 362.60%,均數(shù)倍于后兩者,綜合各指標(biāo)判定其海域圍填和岸線利用效率為三者中最高。后兩者均以沿岸鋪開(kāi)建設(shè)為主,且橫縱比相近,但寧德核電廠采用的海島包圍式圍填導(dǎo)致的岸線損失大,使其圍填效率僅約是珠海貨煤碼頭的1/3。圍填方式、平面建設(shè)形態(tài)(橫縱比)、圍填效率、岸線消長(zhǎng)比例共同決定了海域圍填和岸線利用的效率。這些因素可以通過(guò)工程平面設(shè)計(jì)的改進(jìn)來(lái)優(yōu)化,以提高海岸資源利用效率,減少資源占用及其環(huán)境影響。
[Abstract]:Through the information extraction and comparison of SPOT-5/6 remote sensing images before and after filling in Tianjin Central Fishery Port, Ningde Nuclear Power Plant and Zhuhai cargo Coal Wharf, the difference between reclamation and shoreline utilization in three engineering sea areas was analyzed. The research shows that the construction of Tianjin Central Fishery Port is more favorable to the conservation and utilization of the shoreline, with the filling efficiency of 1.46 km2 / 2 / km, and the coastal line increasing by 1 362.60, with a mean value of more than the latter two. The efficiency of sea area reclamation and shoreline utilization is the highest. The latter two are mainly constructed along the coast, and the ratio of horizontal to vertical is similar. However, the coastal line loss caused by the island surrounding filling adopted in Ningde Nuclear Power Plant is only about 1 / 3 of that of Zhuhai cargo coal wharf. The efficiency of sea area reclamation and shoreline utilization is determined by the way of enclosed filling, the form of plane construction (horizontal to vertical ratio), the efficiency of confining filling, the ratio of shore line growth and decline. These factors can be optimized by the improvement of engineering graphic design to improve the efficiency of coastal resource utilization and reduce the resource occupation and its environmental impact.
