摘要
子午岭次生林区的植被曾经历了人为破坏过程与自然恢复过程。研究结果表明：次生林恢复前该区土壤类似现在的黄绵土；在植被恢复过程中，土壤发育程度逐渐增强，具有一定的腐殖化过程和淋溶过程，土壤向褐色森林型土壤演变；林地被人为开垦破坏后，加速侵蚀迅速发展导致土壤剖面迅速遭到破坏，土壤向黄绵土演变。
Vegetation in Ziwu mountain secondary forest area undergot destruction by human be-ing and natural restoration The researched result showed that before secondary forest restora-tion,soil in this area was similar to present yellow loess soil With secodary forest restoration。soil gradually developed soil formation process was humification and leaching and soil type e-volved form yellow loess soil to brown forest soil But after forest destruction Because of severely accelerated soil erosion soil profile was gradually eroded and damaged and soil changed to yel-low loess soil.
