石羊河流域绿洲农业发展对水资源转化影响的人工神经网络模拟研究

基于石羊河流域绿洲农业发展对水资源转化影响机理的分析,概化了影响流域水资源转化的主要水土资源开发利用要素和反映水资源转化响应结果的状态变量,建立了以水土资源开发利用要素为输入端、以水资源转化响应结果为输出端的BP人工神经网络模型,并利用多年实测资料对该模型进行了训练和检验。检验结果表明,其精度达到了预期要求。利用该模型能够进行流域水土资源开发利用对水资源转化影响的模拟研究。

Simulation about the impact of oasis agricultural development on water resources transforming by the theory of artificial neural network in the shiyang river basin

Based on the analysis of impact mechansism of oasis agricultural development on water resources transforming in Shiyang River basin, the main water and land resources exploitation factors which reflect the degree of water and land resources exploitation are filtered, and the main variables which reflect the state of water resources transforming are filtered too. The BP artificial neural network simulated model is established, the input of which are the main water and land resources exploitation factors,and the output of which are the main variables reflecting the effect of water resources transforming. It's proved that this model can be used to simulate and forecast the impact of water and land resources exploitation on water resources transforming by the process of model training and verifying.
