【摘要】 分析了河南境内红豆杉和南方红豆杉分布与年平均温度、最冷月平均温度、最热月平均温度、≥1 0℃积温、年降水量等 5项气候指标的关系 ,结果表明 :限制其分布的主要气候因子是≥ 1 0℃积温和年降水量 .适宜积温约 3 50 0～ 50 0 0℃ ,年降水量 70 0 mm以上 .红豆杉和南方红豆杉分布区北界为南太行山—中条山 .更多还原

【Abstract】 This paper described the retaliation between the geographical distribution of Taxus chinensis and Taxus chinensis var. mairei in Henan Province and the annual mean temperature, the mean temperature of the coldest month and the hottest month. The results showed that the main climatic factors which restricted the division of Taxus in Henan were the accumulated temperature ≥10℃ and the annual mean precipitation. It is suitable for Taxus that the annual temperature is 3500～5000℃ and the annual precipitation is more than 700mm. The north boundary of the distribution of Taxus in south Taihang～～Zhongtiao Mountains.更多还原
