重庆市有适宜油桐生长发育的优越气候,属于全国油桐中心栽培区.但重庆境内地形复杂,山地立体气候明显,在海拔、气温、降水、日照等多种气象因子影响下,油桐生长分布有一定规律.本文选取1971-2000年气候数据,基于GIS进行空间化分析,同时结合实地调研等相关资料,对油桐生长进行气候区划,划分出光温匹配最适宜区、气候温热适宜区、气候温凉适宜区、气候炎热较适宜区、气候冷凉较适宜区、光照一般较适宜区和气候寒冷不适宜区等7个不同类型栽培区,为油桐种植提供客观的参考依据.
Chongqing has the favorable climate for the growth and development of Tung Oil Tree and belongs to the cultivation area of Tung Tung Center in the country.But the terrain in Chongqing is complex and the three-dimensional climate in the mountain area is obvious. Under the influence of many meteorological factors such as altitude, temperature, precipitation and sunshine, This paper selects climatic data from 1971 to 2000 and carries out spatial analysis based on GIS. Based on field research and other related data, the climate division of the growth of the oil tung tree is divided into the most suitable area for the matching of light and temperature, the suitable area for the warm climate , Suitable climatic suitable areas, hot climate more suitable area, the climate is more suitable for cold area, light is generally more suitable for the area and the climate is not suitable for the cold area of seven different types of cultivation areas for the cultivation of tung to provide an objective basis for reference.
