| 摘 要： | 快速准确地获取城市绿地信息是城市绿地可持续经营和科学规划的基础.以南京市玄武区绿地为研究对象,以2002年SPOT5遥感数据为主要信息源,以同期南京市主城区交通旅游图、绿地统计资料为辅助信息源,通过目视解译获取各类绿地的准确资料.分别采用简单随机、系统、分层、空间平衡抽样4种计算机屏幕抽样方法,对研究对象的绿地信息进行参数估计,并比较分析各种抽样方法的抽样精度.研究结果表明:目视解译结果与统计数据相比,误差仅为5.1%;4种抽样方法的抽样精度大小排序为:空间平衡抽样(98%)(分层抽样(94%)(系统抽样(82%)(简单随机抽样(75%);空间平衡抽样与遥感图像目视解译的误差仅有2%,可以代替目视解译,较大幅度地降低了目视解译的时间、人工成本.
