摘要: 文章基于对四川省干旱半干旱区造林树种选择原则和方法的分析,共梳理出45科97属128种可用于四川省干旱半干旱区植被恢复的乔灌草种。研究发现,豆科植物是四川干旱半干旱区植被恢复中应用最广、适用性强的物种。目前相关研究集中在四川省境内的干热、干暖河谷区,而对干温、德荣乡城半干旱区的研究尚需进一步加强。Abstract: The 45 families and 97 genera and 128 species for vegetation restoration were sorted out on the basis of the afforestation tree species selection principle and the method of analysis in arid and semi-arid regions of Sichuan province.The study found that leguminous plants in arid and semi-arid areas of Sichuan were most widely used to restore vegetation.The related research focused on dry hot valleys and dry warm valleys in Sichuan,but the study of dry temperature and Derong-Xiangcheng semi-arid areas needed to be further strengthened.
