摘  要:
以环境减灾卫星遥感影像为主要数据源,通过计算垂直干旱指数、改进型的垂直干旱指数与植被供水指数,对河南豫北地区冬小麦进行了干旱监测与评价,并对比分析了3种干旱监测指数在不同小麦生育期与土壤相对湿度的相关性.结果表明,改进型的垂直干旱指数比垂直干旱指数干旱监测更为有效,在冬小麦拔节期,植被供水指数干旱监测效果最好.说明利用环境减灾卫星遥感数据进行干旱监测与评价是可行的.

摘  要:
Using HJ-1A /B data as the main data resources,this study monitored the agricultural drought in north Henan Province based on PDI,MPDI and VSWI. The correlation between the three drought indices and the relative soil moisture have been developed in different growing stages of winter wheat. The results showed MPDI presented a better performance than PDI,and VSWI presented a better performance than PDI and MPDI in jointing growth stage. The results indicate that it is feasible for HJ-1A / B data to monitor agricultural drought.
