- Abstract:
- In the paper,soil physiochemical properties of seven plots with same background conditions in the dry-hot valley of Jinsha River were studied.They are the leucocephala land,corn land,mulberry land,sugarcane land,the pepper land,the abandoned grassland and candlenut land.The results show that there is a significant change in soil physiochemical properties after natural water candlenut forest being changed into other land use types,describing as soil organic,total nitrogen,total phosphorus and available nitrogen content was significantly reduced,available phosphorus and soil bulk density did not change significantly and available potassium increased to a certain extent;different ways to use have different effects on it,but generally speaking,the impact on soil physiochemical properties was relatively small after transforming to leucocephala land and abandoned grassland.Composite index of soil properties after the natural candlenut forest changing into other land use types showed a decrease to varying degrees,its decline from small to large order is grass land>leucocephala land>sugarcane land>corn land>pepper land>mulberry land.The more disturbed by man,the more destructive influence on soil quality.So one of the important measures to improve the soil quality is to reduce human activity and increase the return of the amount of soil material in this region.
