【摘要】 利用环境经济学的原理和方法对南充市土壤侵蚀所产生的危害进行了经济学的分析和估算,把土壤侵蚀经济损失的货币化值与经济建设的主要指标进行对比,以此反映水土流失的程度。南充市2002年土壤侵蚀总经济损失为6.22亿元,占当年农业总产值的4.96%,其中养分价值损失为5.50亿元,占土壤侵蚀经济总损失的88.45%,说明土壤侵蚀最直接、最严重的后果是降低了土地生产力。南充市水土流失经济损失最严重的区域是南部县和阆中市,应该进行重点治理。更多还原

【Abstract】 Based on the theory and method of Environmental Economy,the author estimates the effect from soil erosion,and calculate the effect into currency to be compared with main economic items in the areas to reflect the degree of soil and water losses.The total loss for soil erosion in currency is 622 million RMB in 2002,which occupies 4.96% of the agricultural productive value.Among them,the nutrition loss estimated to be 550 million RMB,occupies 88.45% of the total loss for soil erosion in currency.Soil erosion results in bad land productivity.The most severe areas are Nanbu county,Langzhong City of Nanchong,needing to be emphasized for governing.更多还原
