摘要

为更加直观地认识森林的重要生态和经济地位

并为甘肃省生态经济建设的综合决策提供科学的理论依据

实现生态经济可持续发展。以甘肃省重点林区为研究对象

采用物质量和价值量相结合的评价方法

定量地评价甘肃省森林生态系统保育土壤功能和经济价值。结果显示:(1)甘肃省森林生态系统年固土总量为16 620.53万t

年固土总价值为22.10亿元;年保肥总量为988.56万t

年保肥总价值为356.71亿元

森林生态系统年保肥价值占到总固土保肥总价值的94.2%

森林生态系统保肥所产生的价值远远大于固土所产生的价值

占据了主导地位;森林生态系统固土保肥总价值为380.80亿元/年

占甘肃省森林生态系统服务总价值(1 825.92亿元/年)的20.86%。(2)所选取的19种林分类型中

灌木林(222.10亿元/年)在整个森林生态系统固土保肥总价值中占据支配地位

占到总价值的58.32%;乔木林中

其他硬阔类(30.27亿元/年)、栎类(24.25亿元/年)、阔叶混交林(22.22亿元/年)三者固土保肥功能和产生价值较大。甘肃省森林生态系统保育土壤功能及其价值在整个森林生态系统服务中起到至关重要的作用

尤其是灌木林、其他硬阔类...
