Ecochemical Stoichiometric Characteristics of Soil under Different Land Use Patterns
To study the ecological stoichiometry characteristics of soil under different land use modes,two types of land use modes,rice planting(paddy field)and corn planting(dry land)in Yuqing County,Zunyi City,Guizhou Province,were selected as the research ob-jects,and the soil without planting crops was treated as wasteland(control).The content of soil organic carbon,total nitrogen,and total phosphorus was measured and differential analysis was conducted.The results show that:(1)under different land use methods,paddy soil has the highest organic carbon and total nitrogen content,while total phosphorus content is the lowest;the total nitrogen content of dry land soil is the lowest;(2)under different land use methods,the C/N,C/P,and N/P of paddy soil are the highest,and there are sig-nificant differences compared to wasteland and dry land soils;(3)correlation analysis shows that total nitrogen increases with the in-crease of organic carbon content,while total phosphorus decreases with the increase of organic carbon and total nitrogen;C/N decreases with the increase of total phosphorus,while N/P increases with the increase of organic carbon.
