摘要
针对海河平原区的气候特点,在摸清4水转化规律和作物耗水规律的基础上,建立了一套与农田生态耗水相适应的、跨时空调节的生态水利工程体系,为缓和水资源的不足开创了新途径。
In recent years,beoause of less amount and uneven distribution of precipitation, the agricultural development in Cangzhou prefecture was retricted. Water resource is an important component of agroecosystem. The agriculture can achieve outstanding advance only with adequate water.In this paper, in accordance with the characteristics of climate and based on the rules of Four-watet transformation and use of water by crops,a set of ecological water conservancy engineering systems were established, which fit ecological field water consumption and can regulate with time and space, and thus creates a new approach to mitigating the inadequacy of water resource.
