National rural greening and beautification modes in different climatic zones of China based on multivariate statistics of typical villages

Abstract

为了分析阐释我国不同气候带乡村绿化美化模式特点，为建设美丽宜居乡村环境、实现乡村振兴发展目标提供参考，本研究基于374个典型村庄调查，通过SPSS 26.0对乡村绿化美化模式同质集群进行聚类分析，基于Python编程语言构建基于自然断点法原理的分类程序对同质集群的主导模式、各气候带主导同质集群进行分析，得到与乡村所属气候带具有相关性的10组乡村绿化美化典型模式的基础模式组成、模式特征及气候带分布特征。结果表明，10组同质集群中，村庄聚落及周边绿化美化作为主导模式出现的频次高于村庄全域绿化。村庄聚落绿化美化以四旁绿化、居民庭院景观等类型为主，村庄全域绿化以经济林果、观光园、乡村旅游为主。湿润和半湿润地区以风景林营造、古树名木保护、乡村公园与休闲绿地建设、路旁水旁绿化为主，干旱、半干旱地区和高原气候地区以经济林果、观光园、乡村旅游为主。在此基础上，总结得出在聚落人居环境营造、蓝绿空间保护利用、特色农林产业发展、乡村旅游产业发展4类功能导向下，全国不同气候带典型村庄的乡村绿化美化模式特色。

This study investigated 374 typical villages located in different climatic zones.It also analyzed and explained the characteristics of rural greening and beautification modes to provide ideas for building beautiful and livable rural environments while realizing the goals of rural revitalization and development.The study used SPSS software to group homogeneous clusters of rural greening and beautification patterns,then it analyzed the dominant mode and identified the dominant homogeneous clusters in each climate zone using a classification program based on the principle of the natural breakpoint method written in Python.Ten groups of typical models of rural greening and beautification were obtained along with the fundamental model composition,model characteristics,and climate zone distribution characteristics related to the climate zone of the village.The modes of village settlement and surrounding greening and beautification were higher than that of village-wide greening.The greening and beautification of village settlements mainly include surrounding greening and residential courtyard landscaping.Village-wide greening primarily targets commercial forests and fruit trees,tourism gardens,and rural tourism.Greening and beautification measures in humid and semi-humid areas are dominated by forest landscaping and construction,protection of ancient and famous trees,rural parks and leisure green space construction,roadside and water greening.In contrast,in the arid and semi-arid areas and plateau climate areas,these measures dominantly target economic forest and fruit trees,tourism gardens,and rural tourism.On this basis,this paper summarizes the characteristics of rural greening and beautification modes in typical villages in the major climate zones of China under the guidance of four functions:settlement living environment,blue-green space,characteristic agriculture and forestry industry,and rural tourism.
