从海岸滩涂变迁看上海滩涂土地资源的利用

Using of land resources in Shanghai in consideration of seashore beach changes

海岸滩涂是上海市重要的土地后备资源,其在空间与时间上的表现又不尽相同。利用遥感技术可以分析与调查滩涂土地资源利用的分布与变化状况,为科学规划、合理保护和科学论证滩涂资源提供重要依据。该文针对上海市滩涂土地资源利用现状遥感调查,阐述了滩涂遥感信息的提取过程,讨论了其分布结构、多年变化情况,同时结合上海市可持续发展战略,对海岸滩涂开发利用提出了意见。

Seashore beach lands are important land reserves of Shanghai. Its appearance in space and time is rather different. The distributing and transformation of seashore beach lands usage can be investigated by remote sensing technology. These data provides signify basis for beach lands scientific planning, reasonable protection and sound reasoning. Based on remote sensing investigating of seashore beach lands usage in Shanghai, this paper demonstrates the process for abstracting beach lands information, analyzing its proportion and transformation through years. Several opinions are bring forward in the end.
