Abstract:

In order to research the cultivated land security system in hubei province, the indicator system for evaluating cultivated land security development was built through three aspects of quantity, quality and ecology, at the same time, it was also analyzed by information entropy model between 2001 and 2007 in hubei province. The results showed that: the value of the cultivated land system was from 0.12088 into -0.22354 between 2001 and 2007, besides, the value of the cultivated land quantity, quality and ecology were from 0.10358, -0.00286, 0.02015 into -0.22273, -0.00078, -0.00002. This demonstrated that the cultivated land system of hubei province was developing towards an orderly direction and the harmonious degree was increasing gradually, but there were still unstable factors, such as the reduction in cropland acreage per capita, urban rapid expansion, ecological environment deterioration etc. Therefore, on the one hand, the cultivated land consolidation dynamics should be intensified, the urban land intensive degree should be improved; on the other hand, economic, legal and policy should be adopted to raise the quality of cultivated land and improve cultivated land ecology.
