徽州地处中亚热带北缘,是一个典型的亚热带丘陵山区,具有润湿、季风、常绿阔叶林、红黄壤地带自然特征。气候温和,雨量充沛,四季分明。年均温16.3℃,年降雨量1600毫米,无霜期230天,稳定通过10℃的积温5000℃,春夏雨热同期,夏秋光温互补,气候兼南北之长。境内峰峦叠嶂,山谷瑰丽,既有广大的低山丘陵,又有较为宽阔的平原盆地。本区降雨量、日照、气温和湿度因受地形地貌影响,显示出层次性变化,适合于多种作物生长,使植物种群形成水平与垂直分异的立体结构,从而形成“高山林,中山茶,低山果,平地粮和经”的立体格局。
Huizhou is located in the northern margin of the subtropics. It is a typical subtropical hilly region with wetland, monsoon, evergreen broad-leaved forest and red-yellow soil. Mild climate, abundant rainfall, four seasons. The annual average temperature is 16.3 ℃, the annual rainfall is 1600 mm, the frost-free period is 230 days, and the temperature steadily passes through the accumulated temperature of 10 ℃ at 5000 ℃. Rain and heat in spring and summer, the light and temperature in summer and autumn are complementary, and the climate is long in both north and south. The territory of mountainous peaks, magnificent valleys, both the vast hilly, but also a broader plains basin. The rainfall, sunshine, temperature and humidity in this area show a layered change due to the topography, which is suitable for a variety of crop growth and the plant population forms a three-dimensional structure with horizontal and vertical differentiation, thus forming a “mountain forest, Zhongshan tea , Low berries, flat grain and the ”three-dimensional pattern.
