基于Super-SBM模型的云南省耕地利用效率及其影响因素研究

Study on Cultivated Land Use Efficiency and Its Influencing Factors in Yunnan Province Based on Super-SBM Model

利用了Super-SBM模型、热点分析以及地理探测器的研究方法,对云南省耕地利用效率、空间集聚性及其影响因素进行了探究,为云南省提高耕地质量、实现农业可持续发展提供依据。结果表明:(1)2011~2020年云南省耕地利用效率呈现出上升的趋势,研究期内均值为0.60;(2)从空间维度看,云南省耕地利用效率呈现出“西部高东部低、南部高北部低”的格局;(3)从空间集聚性上看,热点显著区主要集中在云南省西部与西南部,冷点显著区集中在云南省西北部,其余区域为随机分布区,热点显著区为耕地利用效率高的地区,冷点显著区为耕地利用效率低的地区;(4)整体而言,自然、社会经济、农业技术条件均对耕地利用效率有一定影响,但是有效灌溉面积占比以及农业机械总动力对其影响最大。总之,不同区域应该因地制宜,精准施策,合理配置资源,促进各地区耕地的高质量发展。

In this paper,the Super-SBM model,hotspot analysis and geographical detector research methods were used to explore the utilization efficiency,spatial agglomeration and its influencing factors of cultivated land in Yunnan Province,so as to provide the basis for improving the quality of cultivated land and realizing the sustainable development of agriculture in Yunnan Province.The results showed that:(1) The utilization efficiency of cultivated land in Yunnan Province showed an upward trend from 2011 to 2020,and the average value was 0.60.(2) From the spatial dimension,the utilization efficiency of cultivated land in Yunnan Province showed a pattern of “high in the west,low in the east,high in the south and low in the north”.(3) From the perspective of spatial agglomeration,the hotspots were mainly concentrated in the west and southwest of Yunnan Province.The cold spot areas were concentrated in the northwest of Yunnan Province,and the other areas were randomly distributed.At the same time,the hot spot area was the area with high utilization efficiency of cultivated land,and the cold spot area was the area with low utilization efficiency of cultivated land.(4) Overall,natural,socio-economic and agricultural technological conditions had a certain impact on cultivated land use efficiency,but the proportion of effective irrigation area and the total power of agricultural machinery had the greatest impact.In short,different regions should adjust measures to local conditions,precise policy,rational allocation of resources,and promote the high-quality development of cultivated land in various regions.
