生态经济学视角下沙漠化治理效益分析——以内蒙古科尔沁沙地为例

Desertification Governance Based on Ecological Economics——An Example of Horqin Sandy Land, Inner Mongolia

近年来随着全球经济的发展,人类对自然资源的破坏愈演愈烈,在中国半干旱的地区,土地沙漠化已经成为一个超越国界的问题.我国是世界上荒漠化严重的国家之一.截至2013年年底,我国沙漠化土地面积已达267.4万平方千米.沙漠化治理在我国已有几十年的历程,然而,沙漠化治理作为一项经济效益在短期很难显现的工程,其效益并未得到很好的度量,这也导致了社会对其关注程度与其重要程度不成正比.本文以科尔沁沙地为例,从生态经济学的角度通过对前人提出的各类沙漠化治理方法效果进行模型化、数据化,从而达到将治理结果可计量化的效果,并将沙漠化治理的效益(服务功能)进行衡量.

With the development of global economy, the human destruction of natural resources in China is growing those years. Semi arid area and desertification of land has already become a beyond the borders of the problem. As of the end of 2013, the area of desertification land in China has reached 2674 thousand hectares, China is one of the most serious desertification countries over the world. The desertification in China has for several decades, however, the desertification as an economic benefit is difficult to show the benefits of the project in the short term and there is no good measure to obtain them. Which also led to the society is not proportional to its attention degree and impor-tance degree. This paper will take Horqin sandy land as an example, from the view of ecological economics by the ef-fect of various types of desertification control methods previously proposed to model, data, so as to achieve the control results can gauge the effects of quantization and desertification control efficiency(service function)measurement.
