中文摘要：

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。

英文摘要：

This article, referring to China vegetation regionalization, Loess Plateau biological climate partition and Loess Plateau planting trees and grass, has divided the Loess Plateau into 3 regions, 5 sub regions and 11 districts. With the climate and environment of the Loess Plateau, this division, taking the whole plant community in the region as a reference, is based on the precipitation and temperature in plant environment factors and the regional distribution and is oriented to the area of rural green construction.Furthermore, on the basis of a lot of research and literature, this article has selected suitable courtyard tree species for residential on different areas and has made a statistical analysis of application frequency of plant species in the key research area, which will provide basic data for the construction and research of rural afforestation in the future.
