Micro-climate observation and vegetable field experiment were carried out during 2009-2013 in mountains areas of Southwest Hubei at different altitudes. Spatial and temporal variation characteristics of meteorological elements such as temperature, precipitation, evaporation was analyzed. The correlation of yield, quality of pepper, lettuce, and other vegetables, and meteorological conditions were also analyzed. The result showed that in the sustain duration with ≥5℃、≥10℃、≥15℃ the decreasing rate with height increasing per 100 m were 4.8 days,5.5 days,6.8 days,respectively. The precipitation and humidity index increased with height increasing. The fruit setting number of single pepper plant(thermophilic vegetable)and per unit area yield both have significant relation with the duration of days≥15℃ in the flowering and fruiting stage. The contributions of each additional day to single plant fruit setting number and yield per unit were 0.32 and 1.10 t·hm-2, respectively. The most suitable planting conditions for warm season vegetables were height between 800-1 200 m, temperature ≥15℃, sustaining for 100-130 days. There was no summer above 1 600 m hight,where was the suitable planting area for hardy vegetables.%2009～2013年在鄂西南山区174～1 800 m不同海拔高度上进行了小气候观测及蔬菜田间试验，对不同界限温度（5、10、15 ℃）、降水量、蒸发量等气象要素时空变化特征以及喜温蔬菜辣椒、耐寒蔬菜莴苣等蔬菜产量、品质与气象条件之间的关系进行了分析。分析表明：≥5 ℃、≥10 ℃、≥15 ℃的持续天数随海拔高度每升高100 m分别递减4.8、5.5、6.8 d，降水量及地表湿润指数均随海拔高度的升高而增加；辣椒单株坐果数、单位面积产量与开花结果期≥15 ℃的持续天数呈显著线性相关，≥15 ℃持续每增加1 d对单株坐果数、单产贡献率分别增加0.32个、73.47 kg·（667 m2） -1；海拔800～1 200 m高度≥15 ℃的持续时间为100～130 d，且无高温天气胁迫，是喜温蔬菜最佳种植带；海拔1 600 m以上高度基本无夏季，是喜冷凉蔬菜的适宜种植区。
