Phosphorus is an indispensable nutrient element for plant growth, while organic phosphorus is an important component of soil phosphorus pool, and its activity is closely related to soil phosphorus supply capacity. With the method of field investigation and indoor analysis, the distribution characteristics of organic phosphorus components in soil aggregates of different types of C. lanceolata stands were studied by taking pure C. lanceolata stands, mixed C. lanceolata and Michelia macclurei forests, and mixed C. lanceolata and Mytilaria laosensis in Pingxiang, Guangxi. The results showed that except highly stable organic phosphorus, which was mainly distributed in large particle size aggregates, the content of organic phosphorus in other components increased with the decrease of particle size, The content of organic phosphorus in aggregate with particle size<0.25 mm is the highest, and the storage of organic phosphorus in aggregate with particle size<2 mm is the highest due to the influence of particle size distribution< The stability indexes of 0.25mm and>2mm aggregates and soil aggregates were significantly positively correlated with the reserves of various organic phosphorus components. On the basis of maintaining soil stability, the reserves of soil organic phosphorus could be effectively increased by increasing the proportion of>2mm and<0.25mm aggregates; Among the three forest types, the mixed forest of C. lanceolata and Michelia macclurei can effectively improve the stability of soil aggregates and increase soil organic phosphorus reserves. Therefore, the selection of suitable mixed tree species will help to improve the quality of soil ecological environment and promote the sustainable management of forest resources.
