本研究采用多目标规划方法建立了丘陵山地开发利用的多目标模型,通过对模型的求解和影子价格分析,得到较为理想的结果。规划后,系统的结构得到优化,生态与经济的目标得到提高。研究结果表明:1)应增加经济林的比重,提高丘陵山地开发的经济效益和产出;2)增加薪炭林的面积,改善农村能源的供给;3)调整用材林的结构;4)大力套种绿肥,增加饲料和有机肥的来源,减少水土流失。
In this study, a multi-objective model for the development and utilization of hilly and mountainous regions was established by using the multi-objective programming method. Through the analysis of the model and shadow price analysis, the ideal result was obtained. After planning, the structure of the system is optimized and the ecological and economic goals are enhanced. The results show that: 1) The proportion of economic forest should be increased and the economic benefits and output of hilly land development should be increased; 2) The area of fuelwood forest should be increased to improve the supply of rural energy; 3) The structure of timber forest should be adjusted; 4) Increase the sources of feed and organic fertilizer to reduce soil erosion.
