川西-川西北地区
补充资料:川西北高原
中国五大牧区之一,四川最大牧业基地。位于省境西北部的甘孜、阿坝藏族自治州境内。面积约20万平方公里。其地理特征是:①地势高平。区内平均海拔在3000~4000米以上,是四川省地势最高地区。地表切割浅,除东南部相对高差500米,地貌上属山原外,其他地区均属丘原,高差一般在100~200米左右,山矮丘缓,丘坡多在5°~20°,为青藏高原东南边缘部分。谷地宽展,阶地广布,并有沼泽发育,以东北部的若尔盖地区沼泽面积最大(见若尔盖沼泽)。②气候奇寒。大部分地区年均温0~6℃,极端最低温-20℃以下,石渠为-38.9℃,有"四川寒极"之称。10℃以上活动积温1000~1500℃,全年长冬无夏,春秋相连,为四川热量最低地区。海拔3500~4000米以上地区种植业绝迹,4000~4200米以上地区则为森林分布的上限。除河谷和谷坡外,大部分地区以牧业为主。本区有草场1067万公顷,牦牛、绵羊等牲畜头数均居四川首位,是四川主要牧业基地。③太阳辐射强烈,光能资源丰富。区内地势高亢,空气稀薄,太阳年辐射量和年日照时数均为四川省最高值。丰富的光能资源在一定程度上弥补了地高天寒、热量不足的缺陷,因而种植业、林业、牧业上限均高于四川省其他地区。
