摘　　要：本文利用解译中巴卫星数据和灌溉入渗系数和渠道利用系数,反演灌溉入渗补给量和渠道渗漏补给量,实现利用遥感数据直接计算灌溉入渗补给量和渠道渗漏补给量的目的。此反演计算方法,对于水资源评价和水环境遥感动态监测有一定的参考意义。Taking the katamu farm of Xinghe county in Xinjiang for example, this paper presents some methods for calculating field infiltration and irrigation canal infiltration of farm by remote sensing image of CBERS. First, extract cultivated area by the image, then calculate irrigation area, and field infiltration; at last, calculate channel inflow and irrigation canal infiltration . In this way, field infiltration and irrigation canal infiltration can be directly calculated. It is a good way for evaluating water resources and monitoring water environment by remote sensing.
