大长山岛土地利用变化及其土地与海域综合利用探讨

Discussion on the Changes of Land-Use and the Land and Sea Area Comprehensive Utilization on Dachangshan Island

当前国内外对土地利用及其变化的研究,多数是对陆域的城市或有关区域的土地利用及其变化的研究,而对海岛土地利用及其变化的研究报道很少。海岛是海中陆地,由岛陆、岛基、岛滩和环岛浅海组成,海岛土地利用及其变化的特征受海陆因素的影响。尤其在海岛的海岸带地段,这种影响更为明显,具体体现在海岸带滩涂土地和浅海水域的利用上。论文对北黄海大长山岛的土地利用及其变化进行了论述;分析了大长山岛土地利用特征、土地利用结构随时间变化的趋势;同时,根据我国颁布的《海域使用法》和《物权法》的内容,对海域与海岛土地的属性以及将海岛土地与海域利用作为一个系统,在理论与法律依据上进行了探讨。

Recently, most studies on land-use and its changes have focused on land cities or related regions at home and abroad, while few on islands. Island is the land on the sea, which is composed of island land, island base, island beach and epicontinental-sea around island. On island, the land-use and its changeable characteristics are influenced by factors of sea and land. It＇s especially obvious in island＇s coastal belt, which can be seen from the use of mud-flat in coastal belt and the epicontinental-sea. This paper discusses the land-use and its changes on Dachangshan Island in North Yellow Sea, and analyzes the characteristics of land-use and the tendency of changeable structure of land-use over time on Dachangshan Island. And based on Area Sea Use Act and Real Right Law authorized by China, this paper also discusses island land and sea area which are considered as one system and their attributes from law and theory foundation.
