武陵山区位于湖南、湖北、四川和贵州四省交界地区,属亚热带季风型湿润气候,温湿多雨,由于受太阳幅射、季风环流、岩溶地貌等综合作用,又受海拔高度、坡向坡位和地形的交错影响,形成了复杂而独特的山地气候,而且历史上受第四纪冰川影响较小,因此保存了种类繁多的生物资源。1978年我们在湖南省湘西土家族苗族自治州发现野生番茄,以后又在武陵山区其他地区发现,1993年在花垣县设野生番茄资源圃,1994年初步调查了的资源分 Wuling Mountain is located in the junction of Hunan, Hubei, Sichuan and Guizhou provinces, belongs to the subtropical monsoon humid climate, wet and warm due to the combined effects of solar radiation, monsoon circulation, karst landforms, but also by the altitude, slope position And terrain, forming a complex and unique mountain climate, but historically affected by the Quaternary glacier less affected, thus preserving a wide range of biological resources. In 1978, we found wild tomatoes in Xiangxi Tujia and Miao Autonomous Prefecture in Hunan Province and later discovered other areas in Wuling Mountain. In 1993, we set up a wild tomato resource garden in Huayuan County and conducted preliminary investigation in 1994
