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。Based on the color aerial photo and the field survey data, this paper analyze the information of various land use type change and spatial characteristics in yanan ecological construction demonstration area from 2000 to 2003 by rs, gis and statistics methods
