摘要
根据黄土高原水土流失的特点,本文采用了生态和经济两个目标函数,应用系统优化理论及系统动力学原理,对宁夏西吉县黄土丘陵区的薪炭林的产量,水土保持及经济效益进行了动态模拟分析。
Based on the characteristics of water and soil loss on the loess plateau,We considered two objective functions on economics and ecology,using systematic optimization theory and systematic dyna- mic principles,and optimized the tree species combination of fuel forest on the loess hill region of XiJi county.The dynamic simula- tion of fuel yield,water and soil conservation effects and economic benefits were also analysed.
