因此,加快退耕還林還草,調整土地利用結構和產業結構,已成為實現山川秀美工程和可持續發展戰略的必經之路。論文以解決陜北地區的收入問題,植被問題以及糧食產量問題為出發點,首先從理論上分析了包絡分析方法在陜北地區退耕還林(草)中運用的可行性,然後結合陜北地區目前的實際情況,綜合分析出影響陜北地區退耕還林(草)的關鍵的七個因素作為輸入指標:水利水保設施投入,農作物投入,經濟林種支出,防護林支出,其它經濟作物,草類支出,畜
牧業投入;以退耕還林所要解決的最終問題作為輸出指標: gdp收入、農民人均純收入、水土流失減少量、
牧業總產值、糧食產量、林業總產值、其他經濟作物總產值。將各指標所對應的數據代入模型后,通過分析求解得出非有效的決策單
元,再運用包絡分析方法的一些基本原理對非有效的決策單
元進行調整,由此所得的數據對陜北地區的實際投入具有很好的指導意義。
