【摘要】：库布齐沙漠是中国第七大沙漠,2000—2015年沙产业发展迅速,规模较大。库布齐模式在国内外影响力很大,实现了防沙治沙和生态经济的双赢。但库布齐模式在科学界也存在较大争议,主要表现在库布齐模式的水资源承载力和沙产业的效益评价方面。运用数据包络分析方法(DEA法)评价了库布齐模式中3种沙产业模式2015年的经济效益。结果表明:在3种沙产业模式中,光伏发电综合利用模式和生态旅游模式投入产出综合效率最高,达到1.000,高于生态饲料加工模式的综合效率且3种沙产业模式的纯技术效率均实现DEA有效;3种沙产业模式投入产出规模效率均较高,均值为0.978,最优为光伏发电综合利用模式和生态旅游模式。在此基础上,提出了库布齐模式存在的问题、沙产业今后发展的方向与对策建议。
[Abstract]:The Kuby desert is the seventh largest desert in China. The development of the sand industry in 2000 to 2015 is rapid and large. The Kuby model has great influence at home and abroad, which has realized the win-win of sand control and ecological economy. But the Kuby model also has great controversy in the scientific community, mainly in the water resources carrying capacity of Kuby model and the effect of the sand industry. By using the data envelopment analysis (DEA), the economic benefits of the 3 types of sand industry models in the 2015 model were evaluated. The results showed that in the 3 types of sand industry models, the integrated efficiency of the integrated utilization mode of photovoltaic power generation and the ecotourism model was the highest, reaching 1, which was higher than the comprehensive efficiency of the ecological feed processing model. The pure technical efficiency of the 3 types of sand industry model is effective in realizing DEA; the efficiency of the 3 types of sand industry model is high, the mean is 0.978, the best is the comprehensive utilization mode of photovoltaic power generation and the ecotourism model. On this basis, the existing problems of the model and the direction of the future development of the sand industry and the countermeasures and suggestions are put forward.
