- Abstract:
- In order to clarify the ecological efficiency and influencing factors of cultivated land in backward areas and realize the coordinated development of resource conservation and ecological protection, based on the panel data of the counties in Lüliang Mountain Area in 2007, 2012 and 2017, the super-efficiency SBM model was used to calculate the ecological efficiency of cultivated land in the counties, to reveal its temporal and spatial evolution features, and to explore the influencing factors of the ecological efficiency of cultivated land by using the geographic detector model. The results showed that ecological efficiency of cultivated land in the study area presented an upward trend, and the stage features were obvious from 2007 to 2017; from 2007 to 2012, the ecological efficiency of cultivated land in most counties increased slowly, and from 2012 to 2017, the increase of that in most counties was larger. However, the ecological efficiency of cultivated land in most counties was at a low state, and there was still a large space for improvement. The spatial difference of cultivated land ecological efficiency in the study area was shrinking, but the spatial correlation of cultivated land ecological efficiency was not significant, which indicated that the development of each county was relatively independent. The ecological efficiency of cultivated land in the study area was the result of the comprehensive effect of socio-economic and natural factors. The economic level, population size, labor force and precipitation were more decisive. The arable land ecological efficiency will be further improved because of the precipitation serving as the supporting condition of the ecological efficiency of cultivated land and the regional economic development.
