Dianchi lake, near by the southern suburbs of Kunming sity of China , is a larger fault lake of plateau (mean altitude of the lake surface is 1885 m area of water is about 300 km2, mean depth of water is about 5 m and ratain water all the year round is about 14 hundred millions ) where is located in plateaumountain of low latitude (22°40' - 25°02' N and 102°27' - 42 'E) in the middle of Yunnan Province.This article is based on long-term data (1970 - 80) of six stations within Kunming basin-lake area of Dianchi. We make use of Anning station (24°56' N,102°29/E) in. the basin area without lake located on the west part of Dianchi lake i, e, upwind region of prevailing wind direction (SW )for comparison.The effects of contribution values of Dianchi lake on air temperature(△T) is defined as.Where Ti, To and Ti/ H, T0/ H are air temperature in Kunming basin region of Dianchi lake and Anning basin region and its lopse rate of temperature, T0/a is the temperature lopse rate of latitude in middle of Yunnan plateau in basin region without lake. By using the T0/ values the temperature of Anning station is corrected to the temperature corresponding to the latitude of each station in Kunming basin region of Dianchi lake.By using elimination method of correction of altitude and latitude , We obtained the effective values of Dianchi-laRe on sir temperature at different levels according to the above formula, see table 9.In this article , annual variation and general characteristics of space change of the effective values on temperature at level land and the foot zone of a mountain in Kunming basin region of Dianchi lake are described.
