The fundamental driving force of the succession is generated from an edaphological endodynamic sacces-sun under the reaction of plant communities in early stage of the sere. As the photointensity decreased in later stage of the sere, endodynamic succession of plant communities took place.

M From 1984 to 1994, 11 000 hectare schist sand were closed to facilitate afforestation. At present, multi-tree species, multi-layers mixed forest were hearly formed. Closing hillsides to facilitate afforestation had advantages of low cost buthigh beneficit, as well as effect on vegetation recovery, water conserving, pest control etc.It was a way to resolve energy shortage in countryside,meanwhile it coald reduce surfare runoff, flood and drought damage.

There are three stages of vegetation recovery and succession on red earth in the low hill area. There are mainly herbarceous plants in the primary, shrubby plants in the secondary and arborous plants in climax. The recovery of anthropogenic vegetation is obviously faster than that of natural vegetation. It took 8-9 years up to the climax stage in the anthropogenic vegetation, but in the natural vegetation only up to the secondary succession stage. It was advantageous for the vegetative recovery to conservating soil and water, decreasing soil nutrient loss and improving soil fertility and the microclimate.

低丘红壤地区植被演替和恢复可分草本植物为主的初级阶段、灌木植物为主的次级阶段和乔木植物为主的顶极阶段。植被恢复进程,人工植被8~9年后就达到演替的顶极阶段,自然植被8~9年仍处于次级阶段。人工植被显著比自然植被恢复快。低丘红壤地区植被恢复不仅有利于保持水土,降低土壤养分的流失,提高土壤肥力,而且能调节小气候,改善生态环境。
