一、新疆昆虫生态地理特点 从昆虫区系来谈,新疆地处中纬度欧洲大陆中心。新疆是我国最干旱的地区,而南疆(天山以南)则为全世界少数极端干旱地区之一。这里有两个显著的特点: 第一是世界上广大荒漠区都处于亚热带,而新疆是处于温带,在气候上属温带荒漠气候带。年总辐射为125—155千卡/平方厘米;全年日照时数为2,550—3,500小时。年平均日较差为11—16℃,有利于光合产物的积累,夏季酷 First, the ecological characteristics of insects in Xinjiang Insect fauna to talk about, Xinjiang is located in the mid-latitude continental center. Xinjiang is the driest region in China, while southern Xinjiang (south of Tianshan) is one of the few extreme arid regions in the world. There are two notable features here: the first is that the vast desert areas in the world are in the subtropical zone, while Xinjiang is in a temperate zone with temperate desert climate. The total annual radiation is 125-155 kcal / cm2; annual sunshine duration is 2,550-3,500 hours. The annual average daily difference of 11-16 ℃, is conducive to the accumulation of photosynthetic products, summer cool
