    分析結果表明：水源涵養林的環境效益顯著，與傳統的僅考慮木材效益的林業經營方式相比，考慮環境效益后將使林業生產實踐和社會福利發生變化；對水源涵養林環境效益給予小幅度的補償如2 . 00 10 . 00即能達到改善環境、提高經營者收益和社會福利的目標，補償水平提高到一定程度以後其作用效果減弱，在經濟水平較低的階段或地區可以選擇較低的補償標準，當經濟水平發展到較高程度以後，可以適當提高補償標準，逐步過渡到完全補償；考慮交易成本以後，使利益相關者的福利有所減少，交易成本幅度在補償標準的10 . 00 50 . 00的范圍內時影響相對較小；目前適合於採用公共支付體系的經濟補償方式，但從長遠來看，創建水源涵養林環境服務市場是一種比較好的補償方式，且政府在水源涵養林環境服務市場制度安排方面仍將發揮重要作用。
