摘要
针对当前河北各区域节水技术模式推广应用综合效益不佳的问题,对资源型缺水的黑龙港平原节水技术模式推广范围进行研究,得出节水技术模式推广应用的潜力系数。主要运用系统聚类分析方法,对黑龙港平原内48个县(市)冬小麦夏玉米生产条件和农业资源条件的相似程度进行了聚类分析,推算出主体节水模式推广应用的潜力空间。结果表明,黑龙港平原吴桥试验站形成的节水模式推广应用潜力达0.88,可以在黑龙港平原广泛推广应用。
The potential of promotion and application for water saving technology mode in water shortage district is studied in this pa- per with the objective to clear the application range of water-saving mode in Heilonggang plain. The similarity coefficient of crop pro- duction condition in 48 counties of Heilonggang plain is discussed by systematic cluster method, and the application potential coeffi- cient of water saving technology mode is inferred. The results show that the application potential of water-saving mode in Wuqiao ex- perimental station of Heilonggang area reaches 0.88, and this mode can be applied extensively in this area.
