【摘要】：平原地区的种植业在我国占据着重要地位,但是频繁发生的旱涝灾害严重影响着我国农业生产,平原水库是解决这一问题的有效措施。对平原水库进行健康评价,保证其正常运营,进而保障农业生产已逐步成为人们关注的焦点。但是与山区水库相比,平原水库健康评价的理论和方法都非常缺乏。针对此问题,首先综合考虑了影响平原水库健康的各方面因素,进而提出了健康平原水库的定义;然后在此基础上建立了包括结构安全、功能效益、生态环境和健康稳定性4个一级指标以及14个二级指标的平原水库健康评价体系,按照健康、亚健康、不健康、病态4个级别进行划分;最后,针对平原水库健康评价的模糊特性,选用可变模糊方法对其进行评价。丁东水库的实例证明,本文构建的平原水库健康评价指标体系合理、概括性强,基于可变模糊的平原水库健康评价方法易于理解、操作方便、结果可信度高。
[Abstract]:The planting industry in plain area occupies an important position in our country, but the frequent drought and flood disaster seriously affects the agricultural production in our country. Plain reservoir is an effective measure to solve this problem. Health evaluation of plain reservoir to ensure its normal operation, and then to ensure agricultural production has gradually become the focus of attention. However, compared with mountain reservoirs, the theory and method of plain reservoir health evaluation are very scarce. In order to solve this problem, the factors that affect the health of plain reservoir are considered comprehensively, and then the definition of healthy plain reservoir is put forward. Then, on this basis, the health evaluation system of plain reservoir is established, which includes four first-class indexes: structural safety, functional benefit, ecological environment and health stability, as well as 14 second-level indexes. According to health, sub-health and unhealthy, The pathological four grades were divided into four grades. Finally, according to the fuzzy characteristics of plain reservoir health evaluation, the variable fuzzy method is selected to evaluate the fuzzy characteristics of plain reservoir health evaluation. The example of Dingdong Reservoir proves that the health evaluation index system of plain reservoir constructed in this paper is reasonable and has strong generality. the health evaluation method of plain reservoir based on variable fuzzy is easy to understand, the operation is convenient, and the result is credible.
