利用AVHRR监测一季混栽作物长势初探

An Approach to Monitoring for Growth Vigour of Mixed Annual Crops with AVHRR

本文根据作物的光谱物征，结合辽宁省的实际情况，划分了５个农业生产力水产相近的监测区域，分析了一季混栽作物遥感监测的可能性，利用气象卫星遥感信息，对旱地作物生殖生长期建立了定量的评价模型。

Based on the spectral characteristics of crops and the actual situation of Liaoning Province, the feasibility of monitoring mixed annual crops with remote sensing was analysed. The areas of Liaoning Province were divided into 5 monitoring regions according to the levels of agricultural productivity. With the data from meteorological satellite remote sensing, quantiative assessment models for rainfed land crops in reproductive period were established. Thus, by the quantative and qualitative assessment mothods presented in this paper, dynamic monitoring for crop growth vigour vigour could be carried out in ten-day periods.
