摘要
根椐１９９０年至１９９６年对苏南孔山地区人为裸露坡面的年际观测结果，分析了坡面的植被自然恢复过程和影响植被自然恢复的自然因素。观测区人为裸露坡面形成的第２年（１９９１年）裸露坡面上植被自然复过程开始出现，１９９６年植被自然恢复过程结束，土壤侵蚀趋于停止。指出人为裸露坡面土壤侵蚀的防治不能只靠植被自然恢复过程来实现。应采取其它措施防治土壤侵蚀。
According to the annual abservation results in 1990-1996 on man-made bare slope in Kongshan mountain ous area of south Jiangsu province,the process and affecting factors of natural recovery of vegetation are analysed. The natural recovery process of vegetation began in 1991 (the year after the formation of mam -made bare slope ).In 1996,the natural recovery process of vegetation was finished and soil erosion stopped.It is put forward that the prevention of soil erosion on man-made bare slope can not be realised only by the natural recovery process of vegetation.It is necessory to take other countermeasures to prevent soil erosion.
