非地带性因素在四川综合自然区划中的作用

EFFECT OF NON-ZONAL FACTOR IN COMPREHENSIVE PHYSICAL REGIONALIZATION IN SICHUAN PROVINCE

四川是山地、高原、丘陵占绝对优势,平原面积狭小的区域;在进行自然区域划分时,应在充分考虑地带性因素(生物、气候)的作用下,着重以非地带性(地质、地貌)为主。这样,才能正确反映四川自然地理综合体分异的真实情况,这在全国和省级的综合自然区划中也是一个突出的特点。

Every physical region takes shape in common effect of zonal factor and non-zonal factor. Most regions in Sichuan province are of mountains, plateaus, and hills. When the physical region is divided, non-zonal factor is the main and zonal factor is the secondary. Non-zonal factor includes geologic and geomorphologic elements there. Such a division is true for physical geographic complex in Sichuan. This is a marked feature in comprehensive physical regionalization of the province.
