摘要:

海湾是镶嵌在海岸线上的明珠,是人类开发海洋和进入内陆的桥头堡,其分类方法多样,大体是从自然属 性或地貌的角度出发的。随着人类经济开发强度的加大,针对海湾开发利用的分类方法成为开发规划或管理的重 要科学基础。为此,就海湾滩涂开发利用与管理考虑,提出了确定海湾范围的标准及海湾分类的定量指标,完成了 对广东海湾的分类,并以此为基础,利用多时期的遥感解译数据,分析了各种类型海湾20 年来的开发利用变化,得 到的结果与海湾实际情况相符,即广东海湾的岸线曲折度整体增加,说明海湾岸线在后退情况下,并没有趋于平直 化,而是由于有些岸段的侵蚀加剧而使得海湾岸线的曲率变大。而广东海湾受围海造田、淤积等因素影响大多海湾 在岸线后退的情况下海湾水域面积却在减少。因此,在以后的海湾开发利用中,应合理规划,保护海湾的生态平衡, 促进海湾的健康发展。

Abstract:

A bay, the hinge of the connection between ocean and inland, is like a bright pear inlaying in coastal line. Scholars have done a lot of research work on it and put forward many classification methods of the bay. However, most of them all are based on classification of natural landscape or landform. With rapid increase in the development intensity, the classification methods can provide scientific basis for development plan or management of the bays. In this paper, the author proposes the definition of bay range and quantitative index of the bays' classification based on development and utilization, and completes classification of the bays in Guangdong. The changes in exploitation of various bays in Gongdong in 20 years are analyzed through RS images in different periods for those areas. According to analytic results, we can conclude that coastline becomes more zigzag due to intensified erosion intensity , reduction of the water area of the bays for enclosing lakes and seas to make cropland and sediment deposition, with the retreat of the coastline. So, in order to protect ecological balance and promote healthy development, we should make reasonable planning for the development and utilization of the bays.
