摘要
运用环境经济学理论与基本方法,估算并分析了临沂市及各县区水土流失经济损失的货币价值。结果表明,临沂市2010年土壤侵蚀经济损失总量为327.7069×106元;各县区单位面积土壤侵蚀经济损失由大到小依次是蒙阴>苍山>沂水>平邑>沂南>费县>莒南>临沭>罗庄>兰山>郯城>河东,表明经济损失是自然因素与社会经济因素共同作用的结果。
Soil erosion caused both on - site and off - site impacts that contributed to economic loss of different extent. On - site impacts included losses of sediments, soil nutrients and water, whereas off - site impacts included soil detainment and siltation, respectively. Based on the date of the re- mote sensing survey on the soil erosion in Linyi City, monetary loss caused by soil erosion were calculated using different methods derived from envi- ronmental economics. Results indicated that economic loss caused by soil erosion in Linyi reached 327. 7069 ~ 106 yuan in 2010. The loss of soil sediment accounted for 37 % of the total loss. Results indicated that physical factors, mainly county size, topography and location were decisive in determining the economic loss due to soil erosion, although human factors may also play an important role.
