晋北地区土地沙漠化经济损失初步研究

晋北地区地处我国北方农牧交错带,沙漠化是土地退化的主要表现形式。土地沙漠化经济损失估值是土地沙漠化研究的重要内容之一,是反映土地沙漠化及其危害程度的主要手段。采用灾害经济评价方法,分析和探讨了晋北地区土地沙漠化经济损失的估算步骤、估算内容、估算参数、估算过程等问题,并对晋北地区因土地沙漠化造成的经济损失进行了初步估算。结果表明:2008年晋北地区土地沙漠化造成的直接经济损失总计约为31.56亿元,占农业增加值的51.28%,间接经济损失预估在142.02亿元以上。

Economic loss of sandy desertification in north Shanxi province

The northern Shanxi province is located in the farming-pastoral ecotone in North China,sandy desertification is a main problem of land degradation in north Shanxi province.Evaluation on the economic loss of sandy desertification is one of the most important subjects in sandy desertification research,and it is a main means to reflect the degree of sandy desertification and its damages.In this paper,by means of hazard economic assessment methods,the procedure,content,parameters,process of evaluation of economic loss of sandy desertification have been introduced,and the economic loss of sandy desertification in north Shanxi province has been evaluated.The results showed that the direct economic loss of sandy desertification in north Shanxi province is about 3.156 billion yuan,which accounts for about 51.28% of primary industry of north Shanxi province,and the indirect economic loss of its is above 14.202 billion yuan.
