摘要：The restoration effect of soil physical and chemical properties of eight forest and grass configuration models such as “Zanthoxylum bungeanum plus Medicago sativa” in rocky desertification areas was monitored in the study.The results show that forest and grass configuration can improve the physical and chemical properties of soil.With the growth of years,the improvement effect of different configuration models is also different,but it basically tends to be good.The soil physical properties of the forest and grass allocation models are basically better than those of pure forest,and the chemical properties are not obviously changed.Some nutrient indicators in all the eight forest and grass models in the experimental area are lower than the standard values of soil nutrients in China,needing to supplement the lacking nutrients in a targeted manner.
