论文以解决陕北地区的收入问题，植被问题以及粮食产量问题为出发点，首先从理论上分析了包络分析方法在陕北地区退耕还林中运用的可行性，然后结合陕北地区目前的实际情况，综合分析出影响陕北地区退耕还林的关键的七个因素作为输入指标：水利水保设施投入，农作物投入，经济林种支出，防护林支出，其它经济作物，草类支出，畜牧业投入；以退耕还林所要解决的最终问题作为输出指标：GDP收入、农民人均纯收入、水土流失减少量、牧业总产值、粮食产量、林业总产值、其他经济作物总产值。将各指标所对应的数据代入模型后，通过分析求解得出非有效的决策单元，再运用包络分析方法的一些基本原理对非有效的决策单元进行调整，由此所得的数据对陕北地区的实际投入具有很好的指导意义。同时，又针对陕北地区在退耕还林过程中以及之后可能面临的困境，提出了一些建议和对策。最终使得陕北地区的投资环境尽快得以改善，使农民尽快脱贫致富，使人口、资源、环境的关系尽快纳入良性循环的轨道上。
