摘　　要：通过实地调查发现郑州市栽培的伏牛山南坡常绿阔叶木本植物共计19科、26属、35种.郑州市≥10℃有效积温、1月份均温能够基本满足所有种类的温度需要;7月份月均温能够满足其中26种的需要.温度因子中的限制因子主要是夏季(7月份)的高温,其次是冬季(1月份)的低温.在伏牛山南坡自然分布下限在500 m以上的种类,难以适应郑州市夏季的高温.建议以分布下限500 m作为郑州市引种栽培伏牛山南坡常绿阔叶木本植物的具体指标.应对郑州市已经引种栽培的伏牛山南坡常绿阔叶木本植物中分布下限在500 m以上的种类实施夏季遮荫处理,对分布上限在500m以下的种类实施冬季防寒处理.There were 19 families, 26 genera and 35 species in Zhengzhou based on field investiga- tion, which came from the south slope of Funiu Mountain. The accumulated temperature（ ≥ 10 ℃ ） of Zhengzhou were entirely suitable to all of them. The year average temperature and the average tempera- ture in January were generally suitable to all of them, and the average temperature in July is only suit- able to 26 species of them. The main limited factors were the highest temperature in July and the lowest temperature in January. The species whose low line of vertical distribution are above 500 m were hard to suite to the high temperature in July in Zhengzhou and those whose high line of vertical distribution are under 500 m were hard to suite the low temperature in January in Zhengzhou. These species should be protected in summer or winter. The low line of vertical distribution of 500 m should be taken as the standand index which can introduce the broad-leaved evergreen woody plants from the south slope of Funiu Mountain to Zhengzhou.
