基于三生视角的内蒙古自治区不同类型土地整治效益评价

为研究不同区域类型的土地整治工程在生产、生态、生活功能方面所体现的效益,选取内蒙古3个不同类型区域的土地整治的案例,采用层次分析法(AHP)、专家打分法和模糊综合评价方法构建三生指标体系,对土地整治后效益进行评价。结果发现土地整治获得的各项效益具有一定的协同提升作用,但体现在各项指标层次上仍具有一些差异:在自然本底条件好的地区获得的生产效益的提升大于自然条件较差的地区;人口密集区域的生产、生活服务性设施的改善明显强于人口稀疏地区;具有较多限制性自然条件地区获得的生态效益的提升大于自然本底条件的区域。因此,在土地整治应该充分做到土地整治工作的开展与当地自然条件相契合,挖掘发展潜力,以现有的生产能力和生态环境为基础,提高整治效益。

Benefit evaluation of land consolidation based on productive-ecological-living function: A case study of three project areas in Inner Mongolia

To investigate the impacts of consolidation,rehabilitation and development on land production,ecology and life benefits,three typical project areas in Inner Mongolia Autonomous Region were selected.The benefits of land consolidation were evaluated by analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method.The results showed that the benefits of land consolidation had some synergistic effects,but there are still some differences among productive,ecological,and living functions.The improvement of production efficiency in the areas with good natural background was greater than that of poor natural conditions.The improvement of the production and living facilities in the densely-populated areas was obviously more significant than that in the sparsely populated areas.The land consolidation should be fully carried out according to the local conditions,digging its development potential to improve consolidation efficiency.
