对川西九龙地区农、林、牧生产布局的初步探讨
A PRELIMINARY EXPLORATION ON THE DISTRIBUTION OF AGRICULTURE, FORESTRY AND ANIMAL HUSBANDRY IN THE JIULONG REGION, WESTERN SICHUAN
【摘要】 根据1979—1981年在九龙地区不同海拔高度的气象观测资料,分析了该区山地气候的垂直变化规律,然后把该区山地划分为4个垂直气候带;山地亚热带(海拔2,100米以下);山地暖温带(2,100—2,450米); 山地温带(2,450—3,050米);山地寒温带(3,050—4,100米)和高山亚寒带(4,100米以上)。根据垂直气候带的变化规律,提出了农、林、牧立体布局的基本模式:1.河谷低、中山种植业带,本带又可分为3个亚带。2.中、高山林业带。3.高山、中山牧业带。
【Abstract】 According to meteorological observation data at different altitudes in the Jiulong Region in 1979-1981, the vertical change laws of mountain climate are analyzed, and four vertical climate zones are distinguished; Mountain subtropical zone (less than 2,100m above sea level) , Mountain warm temperate zone (2,100-2,450m) , Mountain temperate zone (2,400-3,050m) , Mountain cold temperate zone (3,050-4,100m) , Alpine subfrigid zone (More than 4,100m) , Finally, the change laws of vertical climate zones are explained, and a basicmodel for the stereo distribution of agriculture, forestry and animal husbandry is proposed, i. e. 1) Cultivation zone in valleys, low and middle mountains with three subzones; 2) Forestry zone in middle and high mountains; 3) Animal husbandry zone in high and middle mountains.
