基于层次分析的城市树种选择与配置模型设计

Research on the application of internet of things in the optimization of urban forest tree species allocation

在城市树种选择与配置中,由于树木的基本特性不同,导致城市树种选择与配置模型配置后的经济效益差,为此设计一种基于层次分析的城市树种选择与配置模型。从生物学特性、生态功能、景观功能、经济价值四方面建立城市树种选择的指标,并运用层次分析法对这四方面的指标权重计算,同时引入树种的大小比数,计算树种的重要度,对树种配置,以此完成基于层次分析的城市树种选择与配置模型设计。实验以防风故土护堤护岸效益、养护管理成本、树木经济利用价值与树木种植成本四方面衡量此次设计模型的经济效益,结果表明,此次设计的方法提高了防风故土护堤护岸效益、树木经济利用价值,并减少了养护管理成本与种植成本,具备实际的应用意义。

In the selection and configuration of urban tree species,due to the different basic characteristics of trees,the economic benefits of the urban tree species selection and configuration model are poor.Therefore,an urban tree species selection and configuration model based on analytic hierarchy process is designed.Establishing urban tree species selection indicators from the four aspects of biological characteristics,ecological functions,landscape functions,and economic value,analytic process is used to calculate the weights of these four indicators.At the same time,the size ratio of tree species is introduced to calculate the importance of tree species.For the tree species configuration,the urban tree species selection and configuration model design based on analytic hierarchy process is completed.The experiment measured the economic benefits of the design model in terms of the wind protection homeland embankment protection benefits,maintenance management costs,tree economic utilization value and tree planting costs.The results show that the design method improves the wind protection homeland embankment protection benefits,economic use value,and reduced maintenance management costs and planting costs,has practical application significance.
