- Abstract:
-
In order to learn the condition of cultivated land use of Poyang Lake Eco-economic Zone, based on the data envelopment analysis (DEA) method and geographic information system(GIS), we took the county scale as evaluation unit and established the evaluation system of cultivated land use efficiency, then calculated the cultivated land use efficiency of 25 counties in Poyang Lake Eco-economic Zone during the period form 1999 to 2010. Meanwhile, we used the Tobit model to reveal the factors on cultivated land-use efficiency change. The results show that the land-use technical efficiency of Poyang Lake Eco-economic Zone was 0.844 during the period from 1999 to 2010, which indicates that the land-use efficiency is low and there is still more potential to improve it. The technical efficiency was affected by changes in the pure technical efficiency and scale, but the scale efficiency had the significant impact on technical efficiency. There is a great spatial variability of cultivated land use efficiency in the Poyang Lake Eco-economic Zone at county scale. According to the influence factors of cultivated land use efficiency, different factors have different influences with varying degrees of impact on the cultivated land use efficiency. The value can be ranked from high to low level: cropping index, agricultural policy, proportion of the rural population to the total population mechanical total power on unit area and per capital net income of farmers. Finally, the results provide the scientific basis for cultivated land use efficiency and improvement of the potential of cultivated land use in the Poyang Lake Eco-economic Zone.
