【摘要】：以海南万宁日月湾离岸岛为例,分析研究了离岸人工岛的填海方式在环境物理、环境化学和环境生物等方面的正负效应,最后参照国外实证经验,结合我国实际情况,提出具体的应对措施和建议。结论:(1)日月湾人工岛填海造陆引发的较多环境正效应(区别于其他填海造地方式)主要体现在地形地貌效应和生物效应两方面;(2)日月湾人工岛不占用自然岸线,且新形成人工岸线2km,提高了海洋资源利用效率;(3)日月湾岸线冲淤达到再次平衡的时间为6年,最大堆积和侵蚀宽度分别为132m和8m;(4)建议通过围填海立法,加强综合管控,使我国围填海造陆走上有法可依、执法必严的法制之路。
[Abstract]:Taking the offshore islands of Riyue Bay, Wanning, Hainan as an example, the positive and negative effects of reclamation methods on the offshore artificial islands in environmental physics, environmental chemistry and environmental biology are analyzed and studied. Finally, referring to the empirical experience of foreign countries, combined with the actual situation in China, Put forward concrete measures and suggestions. Conclusion: (1) more positive environmental effects (different from other reclamation methods) are mainly reflected in topographical and geomorphologic effects and biological effects, and (2) the artificial islands of the Riyue Bay do not occupy the natural shoreline. Moreover, the newly formed artificial shoreline (2km) has improved the utilization efficiency of marine resources; (3) the time of rebalancing the shoreline of Riyue Bay is 6 years, the maximum width of accumulation and erosion is 132m and 8m respectively; (4) it is suggested that comprehensive control should be strengthened through reclamation legislation. So that our land reclamation on the road to the law, strict enforcement of the law.
