摘要: 农作物长势监测的目的是为早期估产提供依据,同时为田间管理提供及时的信息。笔者总结了中国农作物长势监测的研究进展、研究方法,指出用于长势监测的遥感数据空间分辨率较低,常用的监测指标 具有局限性,监测精度有待提高。“3S”技术的集成发展,进一步实现一体化应用于该领域仍是今后的发展方向。随着农作物长势运行化监测系统的进一步完善,对田间管理的诊断需求会日益加剧,因此作物长势的诊断将成为今后的研究重点。

Abstract: The objects of crop condition monitoring are for early yield estimation and to support crop management. This paper summaries the evolution and methods of studying on crop condition monitoring using remote sensing in our country, and points out that the spatial resolution of remote sensing image selected is very low, and the monitoring index NDVI is limited. Therefore the accuracy should be improved. The integration of 3S (RS, GIS, GPS) which used in the field is the direction of development, and the diagnosis of crop condition will be the emphasis of studying.
