Secondly was honeysuckle and peach tree wood.So,in poor karst area,in order to link environmental benefits,eco-efficiency and social and economic efficiency,it were best measures to plant prickly ash peel or honeysuckle.It can improve capability of holding nutrient in short phase.,also it were beneficial to soil fertility,and hold back soil erosion.Sampled soil in a camphor slope,through analyzed on soil nutritive elements,like that Ca,Mg,Cu,Zn,Mn,Mo,Si,Fe,we had a deeper understanding with soil ground erosion and underground soil leaks.

通过时间对比分析，得出不同土壤利用方式下土壤养分保持能力和土壤退化的变化趋势，提出运用土壤指纹电荷方法对某一研究区域的土壤养分保持能力进行研究，可以减少研究区土壤的破坏程度，只要前期充分展开相关指纹电荷工作研究，制作图谱，后期研究则只需取少量土壤测定土壤pH值后查询前期土壤指纹电荷图谱即可得出某时段内土壤养分保持能力的变化趋势：通过对重庆南平镇石庆村人为生态恢复区不同土壤利用方式下前后一年土壤样品的分析，得出退耕后撂荒草地土壤的各项养分保持指标含量增长最快，对恢复土壤退化程度最为有利，其次是杉树林和樟树林；而从人为生态恢复的各种利用方式来看，花椒林土壤的养分保持能力最好，土壤退化恢复的程度最快，其次是金银花和桃林。
