本論文共分八個部分：第一部分退耕還林概況：筆者在查閱大量資料的基礎上，參閱美國與中國的退耕還林過程中所採取的各項措施並進行比較，得出了以下結論：中國不能重走發達國家先破壞后保護的道路；有計劃、有步驟地實施退耕還林是改善不合理土地利用現象的有力舉措；中國退耕還林經濟基礎較為薄弱，農業勞動生產率低，退耕還林后，必須加大科技含量，提高剩餘耕地的單產，解決糧食自給問題，同時，政府應加強剩餘勞動力轉移，產業結構調整及小城鎮建設的引導；退耕還林的實施仍離不開政府的扶持；依法退耕還林；退耕還林不是在短期內能見到效果的，長期堅持必有成效。該部分最後論述了目前國內退耕還林工程政策、管理方面的現狀及其存在哪些問題尚待改進或繼續深入研究，並需要進一步完善。第二部分退耕還林背景分析：針對我國目前生態環境建設中的退耕還林工程，就其產生的根源從社會經濟背景、生態環境背景及西部大開發三個角度進行了全面、系統的分析。 -
