摘要
本文根据安徽淮北砂姜黑土区农田排水试验资料,采用系统辨识技术,建立农田排水系统的NDDMLPADS模型,模型通用性好,使用方便,为不同排水方式和工程规格条件下,进行农田地下水位动态模拟提供了一个新途径。
With the help of system identification technique and agricultural drain experiments in the area with black shajiang soil in Anhui Province, a simple and general nonlinear dynamic difference model with linear parameters to agricultural drain system
(NDDMLPADS) is developed in this paper. It gives a new measure for accuratly simulatbg groundwater table of field while agricultural drain projects work.
