Abstract This paper analyzed the characteristics of soil nitrogen and phosphorus forms of different crops in the Wuming River Basin in Guangxi, and used principal component analysis to analyze the source of nitrogen and phosphorus in river water and sediments. The results of soil statistics and one-way analysis of variance for different crops showed that the total nitrogen (TN) and total phosphorus (TP) contents of the farmland around the watershed ranged from 802.60 to 2740.42mg/kg and 109.01 to 784.59mg/kg, respectively. The ammonium nitrogen (NH₄⁺-N) and nitrate nitrogen (NO₃^--N) of corn planting soil were significantly higher than other soils (P<0.05); The NO₃^--N of sugarcane soil was significantly higher than other soils (P<0.05); Citrus planting soil Exchanged phosphorus (Ex-P) and iron/aluminum combined phosphorus (Fe/Al-P) were significantly higher than other soils (P<0.05). The results of principal component analysis indicated that TN in Wuming river may mainly originate from nutrient loss of soil planted with corn and sugarcane. Fe/Al-P, Ca-P and NH₄⁺-N in the sediments may mainly originate from citrus, eucalyptus and corn soils, respectively. From the above analysis, it is known that the nitrogen loss of the soil for planting corn and sugarcane may have caused the most important non-point source pollution problem in Wuming River, indicating that the type of land crop is an important factor affecting non-point source pollution in the watershed.

Key words： soil nitrogen and phosphorus forms agricultural non-point source pollution principal component analysis source apportionment
