豫西地区(本文指原洛阳地区所属十五县市)处伏牛山区北段,北纬33°33′—35°06′,东径110°20′—112°55′,属于暖温带大陆性季风气候。农业以一年二熟和两年三熟制为主。年平均降水量600～700mm,大于或等于10℃活动积温4500℃以上;年平均气温13—15℃,一月份平均气温0℃左右。总体上看,全区光照资源丰富,尤以伊洛盆地和黄河谷地各县条件更好。但由于本区降水总量普遍偏少,季节分配很不平均,降水变率大,几乎所有年份都有不同程度的水旱灾害发生,成为本区农业生产中十分突
The western part of Henan Province (this refers to the former Luoyang area belongs to fifteen counties and cities) north of Funiu Mountain, north latitude 33 ° 33’-35 ° 06 ’, east path 110 ° 20’-112 ° 55’, belongs to the warm temperate continental Monsoon climate. Agriculture is one-year and two-year three-year-old-based. The annual average precipitation 600 ~ 700mm, greater than or equal to 10 ℃ active accumulated temperature above 4500 ℃; annual average temperature of 13-15 ℃, January average temperature of 0 ℃. Overall, the region is rich in light resources, especially in the Yiluo Basin and Yellow River Valley counties better conditions. However, due to the generally lower total precipitation in the area, the seasonal distribution is not even, and the precipitation rate is variable. Floods and droughts have occurred in almost all years and become the most prominent agricultural production in this area
