黑龙港平原区冬小麦、夏玉米节水技术模式适应性模糊评价研究

Fuzzy Evaluation of Technique Adaptability of Water-Saving Irrigation Mode in Heilonggang Plain

对3种节水技术模式以生产上的常规灌溉模式为对照进行了技术优属度评价,以期为黑龙港平原主流节水技术模式的推广应用提供理论依据。本研究以模糊集理论和熵信息理论为指导,构建模糊综合评价熵权数学模型,对节水技术模式进行评价。结果表明,黑龙港平原冬小麦夏玉米节水技术模式从优到劣排序为:春2水模式、传统模式(对照)、春1水模式、免春灌模式。春2水模式适宜在黑龙港平原推广应用。

The relative superiority degree of three kinds of water-saving irrigation modes were evaluated of by compared with the con- ventional irrigation mode in this article, which provided theory basis for the extension of main water saving irrigation mode in the Heilonggang Plain. In this paper, the fuzzy comprehensive evaluation entropy mathematical model for water-saving irrigation system was established on the basis of the fuzzy set theory and entropy to evaluate the water-saving technique modes. The result showed that the order of priority for using these water-saving irrigation modes in this region should be： two spring irrigation mode, conventional irrigation mode, one spring irrigation mode and no spring irrigation mode. The two spring irrigation mode is suitable to apply and promote in the Heilonggang Plain.
