成都旅遊天數: 1、成都一日游 |
成都氣候特徵成都市屬亞熱帶濕潤季風氣候區。由於地理位置、地形和下墊面等地理條件的影響,又具有顯著的垂直氣候和複雜的局地小氣候。平原丘陵區屬四川盆地中亞熱帶濕潤和半濕潤氣候區,氣候溫和、四季分明,無霜期長、雨水充沛、日照較少。山區屬「盆周山地」涼濕氣候區,其中海拔1300米以上的中低山氣候冷涼,由夏短冬長到冬長無夏,熱量不足雨水偏多,雲霧常籠罩,終年陽光少,海拔3000米以上高山區,氣候寒冷、無霜期長、光照多,屬高山氣候,形成了「春長溫不高,夏短光照弱,秋涼雨綿綿,冬寒霜雪多」奇異的山區氣候特點。 氣候要素成都氣溫 (1)年、月平均氣溫 成都四季氣候特點 春季:氣溫回升較早,對林木和小春作物生長有利,但忽升忽降不穩定,易出現持續低溫,影響大春作物適時播種。 Located in the bordering areas of the Sichuan northwest highland and Sichuan basin, Chengdu has its own climatic features. First, the eastern part of the city is different from western part in climatic zone, due to the abrupt change of the height from the east to the west. In Chengdu, generally speaking, the west is cool while the east is warm at the same time. Even in the same mountain, the foot of hill is several degrees higher in temperature than that on the top of the hill. This dramatic change in temperature is favorable for the agricultural development. Second, the winter in Chengdu is short, with a long frost-free period of over 337 days each year. The annual average temperature is around 16.4 degree. Even in the cold January, the average temperature is some 5.degrees. It rarely snows. Compared with other areas of the Changjiang River, it is 2-3 degrees higher. Third, there is not much precipitation in winter and spring while it is affluent in summer and autumn with the total precipitation volume of 1,124 centimeters. And this figure is comparatively stable, the ratio of the year with most rainfall and the year with least precipitation being 2:1. Fourth, the climatic elements of light, water and heat almost occur in the same season, which is a very favorable combination to the growth and propagation of the vegetation. Fifth, the wind speed is low. On the plain and in the mountainous areas, the normal speed of wind is around 1 to 1.5 meters per minute. The total sunshine hours average 1,042 to 1412 each year. |
