摘　　要：在滩地种植防浪林,可以减少风浪在堤防的爬高,是有效的生态护岸措施。为合理设计防浪林优化布局、提高防浪林的消波效果,提出了基于模糊熵权法的防浪林布局优选模型。在考虑防浪林的排列方式、行株距、树干半径、树冠半径和林带宽度多种消波影响因素作用的前提下,以在提高消波效果的同时减少经济成本和减少占地面积为目标进行多目标评价决策。以嫩江干流同盟水文站附近堤段为例,采用模糊熵权法优选出防浪林优化布局,推荐行株距2.5 m、林带宽度40 m的等边三角形排列作为嫩江干流防浪林的优化布局。Anti-wave forest is an effective measure to reduce the wave runup and protect the embankment. In order to optimize the layout of anti-wave forest and improve the wave damping effect of anti-wave forest, an optimized layout model based on fuzzy entropy method is proposed. The aim of this selection model is to improve the elimination effect while reduce the economic input and planting area, considering the factors such as forest arrangement, row spacing, trunk radius, crown radius, and forest width. Taking the adjacent section of Tongmeng Hydrological Station in Nenjiang River as an example, the fuzzy entropy method is used to optimize the layout. It is recommended that the equilateral triangle arrangement with spacing of 2.5 m and width of 40 m be used as the optimal layout of the anti-wave forest of Nenjiang River.
