摘要:
利用Landsat系列卫星遥感数据,选取1987、1995、2000、2005、2010、2015七个时相,通过影像预处理、归一化指数与非监督分类方法的综合运用、分类后处理等方法,提取广西沿海城镇建设信息。运用统计学与GIS空间分析方法,对广西沿海城镇近30年来时空格局变化的规律特征进行研究:(1) NDVI、MNDWI、NDBI归一化指数方法与聚类非监督分类方法的综合运用,可以快速提取城镇信息;(2)1990年至2000年和2005年至2010年期间,广西城镇建设面积呈快速增长的趋势;(3)广西沿海城镇建设主要集中在北海市海城区、钦州市钦南区和防城港市港口区和东兴市。研究结果为国土资源、生态环境等相关部门提供参考,为广西海岸带生态风险评估提供数据基础。
Abstract:
Based on the Landsat data of seven time phases, including 1987,1995,2000,2005,2010 and 2015,we extracted the information of costal town in Guangxi by method of image pretreatment, normalized difference index, and supervised classification. We studied the law characteristics of the coastal town construction pattern in Guangxi in the 30 years by using statistics and GIS. The results shows that:(1)The information of town can be extracted quickiy by the integrated application of NDVI,MNDWI,NDBI and unsupervised classification. (2)The area of town construction showed atendency to increase from 1990 to 2000 and 2005 to 2010. (3) The coastal town construction was mainly localized in Haicheng district in Beihai, Qinnan district in Qinzhou, Gangkou district and Dongxing in Fangchegngang. The research results, supplying data foundation for ecological risk assessment of coastal zone in Guangxi, can provide reference for the related departments of land resources and ecological environment.
