| 摘 要： | 本文根据山东省小麦主产区生态条件的区域差异性,以MODIS影像为数据源,分区域、分时段、分模型构建了小麦主产区旱情遥感监测系统,综合考虑土壤质地、风速因素的影响,对热惯量和植被供水指数模型进行修正,确定了野外同步遥感观测场布局及旱情评价指标,依此制定了山东省小麦主产区旱情遥感监测技术流程。

| Abstract: | According to the regional ecological differences among major wheat producing areas of Shandong Province and using MODIS images as data sources,the drought monitoring system by remote sensing was constructed in the sub-regional models.Considering the effect of soil texture and wind speed,the thermal inertia and the vegetation supply water index models were modified and the rules of field monitoring point distribution and the drought evaluation index were determined.Based on these,the process of drought monit... |
