摘　　要：立地类型划分是指对某一特定区域依据不同植被类型,在诸地理因素条件下的生长状况数据分析。通过分析天水市渭河流域刺槐在不同地理因素影响下的生长状况,了解到影响本地区人工造林的主要因素为水分条件,制约因素依次为坡向、坡位。同时对天水市渭河流域造林树种进行了探讨,为本区域造林树种选择提供了科学依据。The classification of site types refers to the analysis of the growth data of different vegetation types in a specific area under various geographical factors,and the summary of the growth conditions of Robinia pseudoacacia in the region under the influence of different geographical factors.The research showed that the main factors affecting the artificial afforestation in this area are water conditions,and the restricting factors are slope direction and slope position in turn.At the same time,targeted systematic analysis of afforestation tree species in the Weihe River basin of Tianshui City provides scientific basis for the selection of afforestation tree species in this region in the future.
