中文摘要:
      筛选嫩江柔性防浪林植物,为嫩江防浪林植物群落模式的构建提供借鉴。构建的嫩江柔性防浪林植物选择指标体系包括消浪功能、生长习性和辅助功能等3项1级指标和根系发达程度、枝条柔韧性、植被高度等8项2级指标。在传统TOPSIS方法的基础上,引入了区间数、三角模糊数及其处理方法,同时在权重确定方法上引入了层次分析法,建立了TOPSIS-AHP 柔性防浪林植物的优选模型。计算结果表明,杞柳、芦苇和芦竹是嫩江柔性防浪林建设的适宜植物,其中杞柳最适宜。未来的研究还应从植物群落角度出发,考虑构建多层次、互惠共生、稳定性强的柔性防浪林植物群落模式或刚柔组合防浪林植物群落模式。
英文摘要:
      Because they are ecologically sound and cost-effective, wave break forests are widely used for attenuating waves to protect river banks and shorelines. But plant selection for bank protection is complex, and plant growth characteristics, climate, soil characteristics and wave dissipation efficiency must all be considered and optimized. In this study, we developed a plant selection index system for a flexible wave break forest along Nenjiang River and then used the system to select plants for the forest. Our aim was to provide a reference to guide plant community development for ecological restoration projects. The TOPSIS-AHP model, developed to assist plant selection for the flexible wave break forest, was based on the traditional TOPSIS method and included the interval number, triangular fuzzy number and processing techniques. The plant selection index system consisted of eight indicators, grouped into three first-level indices:wave attenuation function, growth habits and auxiliary function. Index weighting for each of the eight indicators was determined using the Analytic Hierarchy Process (AHP). A five-level qualitative description for each of the eight indicators was developed, along with the corresponding criteria. The index values of ten plants were evaluated and the suitability degree of each plant was determined. Results show that Salix integra, Phragmites communis and Arundo donax were suitable for constructing the Nenjiang flexible wave break forest, with Salix integra ranking highest. Future research should focus on establishing wave break forests that are multi-level, mutually beneficial and stable, based on the rigid-flexible plant community model.
