由于我县位于四川西南部,凉山东北部,地处大凉山腹心地带。地理座标东径102°53′~103°21′,北纬28°02′~28°54′。最高海拔4042m,最低海拔640m,平均2200m左右,年均温度11.5℃,气候特点是“一山有四季,十里不同天;日出暖烘烘,遇雨便成冬”。干湿分明,由于相对海拔高差达3402m,故山高坡陡,造成水土流失严重,加上微地形造成小气候复杂多样,出
As my county is located in southwest Sichuan, Liangshan northeast, is located in the heart of Liangshan Strip. The geographical coordinates of the eastern diameter 102 ° 53 ’~ 103 ° 21’, latitude 28 ° 02 ’~ 28 ° 54’.
