摘　　要：利用图书馆和网络数据库检索工具,通过对包含＂川榛＂字段的各类书籍、文献的整理,对川榛遗传资源的分类地位、分布范围及其研究利用现状等内容进行了归纳总结,并通过对川榛分布区代表样点气象数据的统计,对其适生的生态条件进行了分析。结果表明：川榛（贵榛、黔榛）主要分布于中国102°06＇～121°26＇E,26°29＇～36°58＇N之间,年均温6.1～19.3℃的广大区域,覆盖全国15个行政省区、直辖市,自然分布以山坡地为主,跨越温带、暖温带和亚热带,具有广泛的生态适应性;分布范围、生态习性、植物学性状、孢粉学和遗传关系等方面的资料表明,川榛与平榛存在明显的差别,两者应为独立的种;川榛具有较高的经济价值和育种价值,但其开发利用进展缓慢;川榛遗传资源的调查与保护、种群多样性及杂交利用等研究工作亟待开展。此研究可为今后开展川榛遗传资源的调查、收集和评价工作提供依据。In this study,the taxonomy,distribution,development and utilization of Corylus kweichowensis Hu were summarized based on the records of books and the literatures collected form libraries and network datebase.The suitable ecological conditions were analyzed through the statistics of the meteorological data of the representative distributed sites.The results showed that C.kweichowensis Hu was mainly distributed in the area of east longitude102°06＇-121°26＇,northern latitude 26°29＇-36°58＇,covering 15 administrative provinces or municipalities.The natural distribution of C.kweichowensis Hu was dominated in hilly land,spanned temperate,warm temperate and subtropical zone,with an average annual temperature of 6.1-19.3℃.Thus,C.kweichowensis Hu had an extensive ecological adaptability in the southern part of China.In the aspect of distribution range,ecological habits,botanical characters,palynology and genetic relationship,evidences to date indicated that C.kweichowensis Hu had obvious difference with C.heterophylla Fisch.,they should be two independent species.C.kweichowensis Hu had high economic and breeding values,but its development and utilization were very slow.It was urgent to carry out research works about the investigation,protection,population diversity and the hybrid use of C.kweichowensis Hu.This study performed would provide references for the future investigation,collection and evaluation of C.kweichowensis Hu genetic resources.
