为获取平潭岛各土地利用类型状况的分布数据,采用Google Earth的历史影像库数据对平潭岛中东部的土地利用类型和坡度、坡向等地形因子进行了提取分析。结果表明:平潭岛中东部地区主要土地利用类型有耕地、建设用地、林地、沙滩、裸露山地、水产养殖地和水域等7种类型,总面积约18 541hm2,其中基岩海岸裸露山地主要分布在澳前镇、东庠岛、流水镇和敖东镇等地区,中东部地区地形以平坡和缓坡为主;坡向以平面坡为主,其次为东南向、西北向、东向和西向,南向和北向的坡面面积较少。
In order to obtain the distribution data of the bare mountain on the rocky coast of Pingtan Island,the land use type,slope,aspect and other terrain factors in the middle and eastern part of Pingtan Island were extracted and analyzed using the Google Earth historical image database.Result shows that the main types of land use in the central and eastern parts of Pingtan Island include arable land,construction land,forest land,sandy beaches,exposed mountainous areas,aquaculture lands,and waters.The total area is about 18 541 hm2,of which the bare rocky mountains are mainly distributed in Aoqian Town,Dongyang Island,Liushui Town Aodong Town.The slopes of the central eastern regions are mainly flat slopes gentle slopes;the slopes are mainly flat slopes,followed by the southeast,northwest,east west.The slope area in the south and the north is less.
