太行山中南部立地类型划分研究

摘要

Different height and size mountains formed because of orogenic time and strength difference during orogeny in Taihang Mountain .Four site types of low mountains , middle-low mountains , middle mountains , middle-high mountains in south central Taihang Mountain were classified according to geomophic law and regetation type .According to slope aspect and geomorphology , 17 site types were classified under altitude .Tree and shurb species were proposed for 17 site types with the survey of native tree species .According to site types and biology and ecology characteristic of indicator plant , suit-able tree species were proposed for water and soil conservation forest , water source conservation forest , economic forest and timber forest .%太行山在造山运动过程中由于构造时间和强度的差异，在地貌上形成了高低、大小不一的山体。依据地貌形成规律和植被类型，将太行山中南部分为低山、中低山、中山、中高山4个立地类型亚区。在海拔的控制下，再根据坡向、地形部位划分出17种立地类型；结合乡土树种分布调查，为17种立地类型提出了可选用的乔灌木树种；根据立地类型和指示植物生物学与生态学特性进行宜林性质划分，提出了水土保持林、水源涵养林、经济林、用材林的适宜树种。
