Morlet　wavelet　time-frequency　correlation　analysis　is　used　to　conduct　empirical　research　on　the　relationship　between　water　quality　influencing　factors.　This　method　can　analyze　structural　changes　in　the　time　domain　as　well　as　short-term,　mid-term　and　long-term　correlations　in　the　frequency　domain.　The　research　results　show　that　there　is　a　highly　significant　correlation　between　dissolved　oxygen　content　and　turbidity　in　the　water　body　in　the　long-term,　and　the　water　body　has　long-term　or　short-term　pollution.　Finally,　this　article　believes　that　the　research　method　of　water　quality　influencing　factors　based　on　wavelet　transform,　as　a　new　auxiliary　method　of　water　environment　management,　can　provide　help　to　managers.
