摘要
简要分析了河北省唐山市农业发展现状,采用定额法对唐山市农业中远期发展进行预测,并采用基于定额的需水预测方法对唐山市近、中、远期不同降水保证率下,平水年、中等干旱年和特枯年情况下农业需水预测,由预测结果,可以看出,唐山市农业需水量呈逐渐减少趋势。
This article briefly analyzes agricultural development status of Tangshan city in Hebei province, and predicts medium-and-long term agricultural development by quota method.
