| 摘 要： | 利用遥感进行农情监测其费省效宏的优势是显而易见的,同时必不可少的抽样调查是提高遥感监测精度的重要手段。在"3S"技术的支持下,基于经典统计抽样原理,结合空间统计学理论发展起来的空间抽样技术在农情遥感监测中的应用日益广泛。文章对国内外农情监测中空间抽样技术应用进行了全面回顾,分析了存在的问题,并探讨了其发展趋势。

| Abstract: | It is obvious that using remote-sensing technology to supervise agriculture information can safe money and have good efficiency.At the same time,necessary sampling investigation is an important mean to improve the accuracy of remote-sensing supervision.With the support of "3S" technology,based on sutra sampling theory,the space sampling technology developed by combining space statistic theory has been widely applied in remote-sensing supervision of agriculture information.This paper reviews the internal and external application of space sampling technology in supervising agriculture information;analyzes the existing problems and discusses about its development trend. |
