中文摘要	大面积农作物生长状况的监测是一个比较复杂的问题，目前还没有较为成熟的办法。我国已经完成和正在开展的农作物遥感监测与估产主要是在华北平原和东北平原等大面积农作物种植区，而西北内陆特别是新疆这样的耕地零星分布、具有特殊的地理环境和气候特点的地区，很少有人涉足这方面的研究。本文以遥感信息为主，在地理信息系统和全球定位系统的支持下，以新疆北部为实验区，通过对相邻年份归一化植被指数（NDVI）的对比，结合野外调查与历史产量的分析，实现大面积农作物长势监测。该方法将遥感技术的宏观快速、地理信息系统的信息管理和空间分析以及全球定位系统的精确定位监测有机地结合起来，取得良好的应用效果。
英文摘要	It is difficult to monitor growing crops in a large scale. There isn’t, up to now, a satisfied method to know what the way a crop is growing and how can get accurate yield estimations of the growing crops, which scientists have been intending to probe into. Remote sensing was used to monitor growing crops in North China and Northeast China. However, in arid land of Xinjiang in Northwest China, this method has not been used because of special geographical environment. In this paper, the researched subject is the winter wheat planted on the northern slope of Tianshan Mountains. A new method to monitor growing crops was experimented supported by modern spatial technology which integrated remote sensing, geographic information system, global positioning system, and other measures such as intensive ground surveys and the analysis for the situation in its history, in order to obtain more exact results. Geographic information system and global positioning system were properly integrated by GVG sampling system for the purpose of monitoring crop growth with the support of GVG system. Field investigations for the growth of winter wheat has been carried out and the database for yield evaluation has been built, which will be not only used to analyse the growth of crops, but also used to estimate the crop yield more exactly by contrasting the result from remote sensing imageries with information from intensive ground surveys. Three methods were used in estimating crop yield: remote sensing aided by GIS, field investigation and analysis for historic yield. It was showed that crop growth monitoring and yield estimation using this integratied method is practical, which should be extensively applied in arid land in Northwest China.
