在借鉴中国植被区划、黄土高原生物气候分区和黄土高原种树种草已有区划研究工作的基础上,以植物环境因子中的水和温度因素的地带性分异规律为依据,以区域整体植物群落为参照,以黄土高原气候环境背景为基础,以地区乡村绿化建设目标为导向,将黄土高原民居绿化植物划分为3个地区、5个亚地区、11个区。并在大量调研和文献整理的基础上,甄选出适合各区域的民居院落绿化树种,同时对重点研究区植物种类的应用频度进行了统计分析,为今后地区植物与民居生态共生关系研究、乡村绿化建设和生态环境研究提供基础资料。
On the basis of the zoning research on the Chinese vegetation division, the biological climate division of the Loess Plateau and the seed-bearing grass planting on the Loess Plateau, based on the zonality of the zonation of water and temperature in the plant environmental factors, Based on the climatic and environmental backgrounds of the Loess Plateau, the greening plants in the Loess Plateau are divided into three regions, five sub-regions and eleven regions based on the goals of regional rural afforestation. On the basis of a large amount of research and literature review, we selected greening tree species suitable for residential areas in each area, and analyzed the frequency of plant species in key research areas for the study of the ecological symbiosis between plants and residential areas in the future. Green building and ecological environment research to provide basic information.
