基于遥感与GIS技术的深圳市1979-2014年填海动态变化及其影响因素分析

On Dynamic Changes of Reclamation and Its Causes in Shenzhen during1979and 2014Based on Remote Sensing and GIS Technology

文章以深圳市作为研究对象,利用遥感和GIS技术,对1979-2014年间5个时期的多源数据进行分析,获取了深圳市近35年以来的填海变化数据,并以此为基础,分析深圳市的填海动态变化特征及其驱动因素。研究表明:1979-2014年间,深圳市填海总面积约74.77km2,其中,西部海域为62.75km2,占比为83.9%,东部海域12.02km2,占比为16.1%;从填海规模和发展速度来看,深圳市填海变化具有明显的阶段特征,大致分为起步发展阶段、快速增长阶段、优化扩张阶段和控制增长阶段;影响深圳市填海变化的驱动力,主要来源于社会经济、土地资源、使用价格、政策法规及生态环境等五大因素。最后,文章结合填海变化及驱动因素分析成果,对新时期的深圳市填海活动提出合理性建议。

This paper had made a comprehensive analysis of land reclamation of Shenzhen in the recent 35 years based on satellite images acquired at 5 different periods from 1979 to 2015 by u-sing RS and GIS technologies.The characteristics of reclamation changes and the driving factors were systematically analyzed.From 1979 to 2014,the total reclamation area was about 74.77 km2 , 83.9% of which was in western coast with an area of 62.75 km2 ,and the eastern coast was 12.02 km2 ,ac-counting for 16.1%.According to the characteristics of reclamation scale and developing speed, the history of land reclamation in Shenzhen could be divided into 4 phases involving the initial stage of development,the rapid growth stage,the optimization of expansion stage and the con-trolled growth stage.The driving force of reclamation in Shenzhen city mainly lies in five factors, including social economy,land resources,price,policies and regulations as well as ecological en-vironment.At last,this paper put forward reasonable suggestions on the Shenzhen reclamation in the new period,based on the analysis of the changes of the land reclamation and the driving fac-tors.
