中文摘要	大面积棉花的生长状况监测比较复杂,目前还没有比较成熟的方法.以往遥感监测应用较多的是NOAA-AVHRR数据,监测精度和监测效果不高.本文利用新一代传感器MODIS 数据,结合实测的地面农作物生长发育农学参数,系统地分析了石河子地区棉花播种到收获整个田间遥感归一化指数(NDVI)及其对应的叶面积指数(LAI)的变化规律,证明MODIS 叶面积指数和实测LAI有很高的一致性,MODIS LAI 的变化状况与棉花长势变化基本一致,实现了较为精确的石河子地区大面积棉花长势的遥感动态监测.
英文摘要	To monitor growing crops in a large scale is a complicated problem and a satisfied method to know what the way a crop is growing has been sought by the scientists in the field. Remote Sensing was used to moni-tor growing cottons with NOAA-AVHRR data usually. However, with the development of the sensor, NOAA-AVHRR was replaced by MODIS (Moderate-resolution Imaging Spectroradiometer). In this paper, the re-searched subject is the cotton planted on the northern slope of Tianshan Mountains. A new method to monitor growing cottons was experimented with modern spatial technology, which integrated MODIS data (2002) and the observation of agronomic parameters of crop growth in order to obtain more exact results. The intergraded method were used to analyze the patterns of normalized vegetation index (NDVI) and leaf area index(LAI)for cotton from planting to harvest, which proved that the MODIS LAI was consistent with the measured LAI, and the variety of MODIS LAI was consistent with the variety of the growth of cotton. It showed that cotton growth monitoring using intergraded method is practical, which should be extensively applied in arid land in the Northwest China.
