【摘要】 以2000和2010年两个时期的卫星遥感影像为依据,对各期遥感影像数据预处理,依据各类对象在数字影像上的光谱特征,快速提取海岸线,对比分析两个时期江苏省海岸线的变化特征,结合数理统计方法和空间分析技术,对江苏省海域使用现状、海域分布规律等进行研究.结果表明:近10年来,江苏省沿海地区整体保持向海推进势态,海岸线长度增加,围垦面积增加,特别是江苏沿海中段,射阳河口至团结港一带,变化最为迅猛.更多还原

【Abstract】 Based on the satellite remote sensing images of 2000 and 2010years,the current situation of Jiangsu sea area is analyzed in this paper.The remote sensing image data are processed with geometric correction,mosaic cutting,and image enhancement and so on.According to the spectral characteristics of various objects in the digital image,the method of human-computer interaction is used to quickly extract the coastline.And then the variations characteristics of two periods of the coast of Jiangsu are analyzed comparatively,temporal information of Jiangsu area are extracted.Combined with the mathematical statistics method and spatial analysis technology,the current situations of the use of Jiangsu sea area and waters distribution were studied.更多还原
