基于高分辨率遥感影像的围填海图斑遥感监测分类体系和解译标志的建立

Establishment of remote sensing monitoring classification system and interpretation criteria for the reclamation area based on the high- resolution remote sensing image

围填海是一把双刃剑,一方面可以缓解土地资源紧缺的问题,另一方面也会给沿海生态环境带来负面影响。如何合理地监测和管理围填海,以便政府掌控和决策分析,首先迫切需要制定围填海的分类体系。围填海是一个海域向陆地转变的中间态过程,将海域使用分类体系和土地利用现状分类体系相衔接,基于年度提取的多源高分辨率遥感影像围填海图斑的可解译程度、围填海的定义、用途属性和形成机理等因素,制定了应用于围填海年度遥感监测的分类体系。此外,根据该分类体系,建立了基于多源高分辨率遥感影像的围填海遥感监测解译标志。

Reclamation is a double- edged sword： on the one hand,it can ease the shortage land resources,but on the other hand,it also brings serious negative effect to the coastal ecological environment. The first step is to make the classification system of reclamation in order that the government can monitor and manage reclamation reasonably for controlling and making decision. Reclamation is an intermediate process from sea to land,and this paper tries to connect sea use classification system and status of land use classification so as to make the classification system used in reclamation annual monitoring by remote sensing based on the level of multi- source high- resolution remote sensing image which can be interpreted,the definition of reclamation,the use properties and formation mechanism of reclamation and other factors. In addition, corresponding to the reclamation classification system of remote sensing monitoring, this paper has established remote sensing monitoring interpretation criteria of reclamation based on multi- source high- resolution remote sensing image.
