Title: Integrated evaluation on the cultivated land consolidation potential of Lanzhou by entropy weight method
Abstract: The potentiality of cultivated land consolidation in Lanzhou was evaluated with entropy weight and synthetically evaluation methods based on the construction of evaluation index system,the purpose was to lay a foundation for land exploitation and consolidation plans,and determining key region and key project during implement of land consolidation in Lanzhou.The results indicated that:the potentiality of cultivated land consolidation could be evaluated with four indexes,increasing of grain output per person,increasing of cultivated land per person,increasing of total grain output and increasing coefficient of cultivated land,these four indexes could be weighted as following order: increasing of grain output per personincreasing of cultivated land per personincreasing of total grain outputincreasing coefficient of cultivated land.It showed that the social and economic benefits of cultivated land consolidation were much important than the area increasing of cultivated land.The potential of cultivated land consolidation in Lanzhou was divided into four grades,the highest grade included Gaolan county,Yongdeng county and Yuzhong county;the second grade included Qilihe district;there was no potential in Anning district.In term of single index,through consolidation of cultivated land,Yuzhong county had the most increasing areas of cultivated land,Gaolan county had the most cost-effective and Yongdeng county had the highest social benefits.
