介绍了山东省水土流失现状 ,分析其危害 ,重点探讨了水土流失经济损失和生态价值损失的计算方法 ,建立经济损失计算模型 ,提出水土流失生态—经济面积边际损失比的概念 ,计算山东省县域边际损失比 ,并对其进行区域分布规律分析。
The actuality and harms of soil and water loss in Shandong Province is analyzed, and the calculating way on economy loss and eco-value loss of soil and water loss are discussed as emphases.
