对多年野外调查资料进行分析研究，结果表明，天目早竹主要分布于天目山山脉、黄山山脉和白际山脉中北部地区，其分布中心在天目山脉的清凉峰一带。其生态学特性为：①适生于中、低山的阴湿区，以海拔８５０～１０５０ｍ的阴坡、半阴坡地段生长最佳，平原和丘岗地则较差；②其气候生态幅度为年均气温８．２～１５．ｇ℃，极端低温－１８℃，≥１０℃年积温３１００～５０００℃，无霜期１８０～２４０ｄ，年降水量１３００～１９００ｍｍ，空气相对湿度８０％以上；③在千枚岩、板岩、页岩等发育的酸性土壤上生长表现较好，花岗岩、石灰岩发育的土壤则较差。据此，天目早竹可在华东、华中的中亚热带北部地区引种栽培。
The field investigation data for many years were analyzed and studied. The results showed that the early stage of Tianmu was mainly distributed in the Tianmu Mountains, the Huangshan Mountains and the central and northern parts of the Baijishan Mountains. The distribution center was located in the Qingliang Peak of the Tianmu Range. Its ecological characteristics are as follows: (1) It is suitable for growing in the wet areas of middle and low mountains, with the shady slopes of 850 ~ 1050m above sea level, The average annual temperature of 8.2 ~ 15. g ℃, extreme low temperature -18 ℃, ≥10 ℃ annual temperature 3100 ~ 5000 ℃, frost-free period 180 ~ 240d, annual precipitation 1300 ~ 1900mm, air relative humidity 80%; ③ In phyllites, slate, shale, etc. Development of acidic soil growth better, granite, limestone soil is poor. Accordingly, the early head of Tianmu can be introduced and cultivated in the northern subtropics of eastern China and central China.
