Abstract: Farmland soil moisture was a key factor affecting agricultural production. In order to solve the problems of few monitoring points, poor monitoring timeliness and difficult regional distribution evaluation of farmland soil moisture, an operational system for the fine evaluation of farmland soil moisture in Xuzhou was established. This system was established based on the CLDAS soil moisture analysis product using Python programming language. The system was easy to operate, can realize the comprehensive, accurate, rapid and rolling monitoring of farmland soil moisture, and met the requirements of large-scale regional evaluation and small-scale fine evaluation of farmland soil moisture.

Key words: farmland soil moisture, CLDAS soil moisture analysis product, Python
