（ 2 ）通過對全新世渭河流域成壤環境演變問題的討論，揭示了全新世渭河流域土壤的發育具有階段性，表現為由溫濕的強成壤期向冷乾的沉積期（弱成壤期）演變、再向溫濕的強成壤期演變的規律；黃土一古土壤序列是不同生物氣候環境下、不同成壤過程發育的不同土壤類型演替而形成的復合型土壤剖面體系；而且由於冬夏季風環流及其環境效應在空間上的差異，使得復合型土壤剖面體系也存在著南北差異。The quaternary environmental evolution of the beijing plain region mainly depends upon the neotectonics and palaeoclimatic changes, which controlled and influenced the distribution, evolution of depositional areas and uplifting erosional areas and changes of sedimentary types, and also the scale and scope of quaternary transgressions
