一、紫阳环境概述紫阳位于大巴山北坡,北纬32°48′以南,根据紫阳气象站20年的资料统计分析:全年平均气温15.1℃,最冷月气温平均为3.7℃,绝对最高气温41.3℃,绝对最低气温为-7.6℃,降水量为1127.8mm,日照百分率为36％,相对湿度为78％,平均风速为1.6米/秒。根据气候带指标和气象资料分析,如以≥10℃的各年平均积温4669.0衡量,本地区北亚热带气候就只能划到海拔700米以下,如用最冷月(元月)平均气温3.7℃衡量,可划到1000米;按照茶树生长情况,以划在900米以下较适当。本县北亚热带的面积为172.635万亩,占全县境面积的51.1％。
Ziyang Environment Overview Ziyang is located on the northern slope of Daba Mountain, latitude 32 ° 48 ’north, according to Ziyang weather station 20 years of statistical analysis: the annual average temperature of 15.1 ℃, the coldest month average temperature of 3.7 ℃, the absolute maximum temperature 41.3 ℃, the absolute minimum temperature is -7.6 ℃, the precipitation is 1127.8mm, the sunshine percentage is 36%, the relative humidity is 78% and the average wind speed is 1.6m / s. According to the analysis of climatic index and meteorological data, if the average accumulated temperature in each year ≥10 ℃ is 4669.0, the northern subtropical climate in this region can only be planted below 700m above sea level. For example, the average temperature of the coldest month (January) is 3.7 ℃ Measured, can be drawn to 1000 meters; in accordance with the growth of tea trees to plan more appropriate in the 900 meters below. The northern subtropical area of 172,635 acres, accounting for 51.1% of the county area.
