Eucalyptus tree-Ageratina adenophora compound system is considered as a new invasion in Yunnan,southwest China in recent years.In this paper,the effects of A.adenophora invasion on soil phosphorus,soil potassium in E.plantation were investigated,based on the exploration of its causes,the assessment of its risk and the prediction of its succession.The results showed that the invasion had a different effect on four different chemical indexes(TP,AP,TK,AK)of soil in E.plantation,characterized with a certain complexity.Its effect on soil phosphorus(TP,AP)and soil potassium(TK.AK)was related to seasons,exposure and invasive degrees of A.adenophora,but there was no unified rule for them,which should be studied further.Its expected to provide a theoretical basis for the sustainable operation and scientific management of E.plantation under the condition of A.adenophora invasion.
