Abstract 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.
