摘要:

耕地作为干旱区绿洲农业发展的基础性资源,明晰耕地利用生态效率演变规律对区域社会经济发展及生态保护具有重要意义。基于2014—2021年新疆85个县域耕地利用数据,采用超效率SBM模型、莫兰指数(Moran’s I)、固定效应模型等方法测度分析了新疆耕地利用生态效率时空演化规律及其驱动因素。结果表明:(1) 2014—2021年新疆耕地利用生态效率总体处于较低水平,但呈现波动中上升态势,增长了17.02%。(2) 新疆耕地利用生态效率空间分布高-高集聚区呈现由“双核集聚”向“点状分散”的变化特征,低-低集聚区呈现集聚-扩散-集聚的变化特征。(3) 水土协调比例、农业专业化服务、人均农业产值、机械化水平、地膜覆盖率等是影响新疆耕地利用生态效率变化的重要因素。未来新疆各县域耕地利用生态效率的提升应注重水资源、生产技术、经济水平等各个因素之间的协调,推动耕地产能的提升同时减少耕地利用的负向外部性。

Abstract:

An understanding of the evolution of ecological efficiency in cultivated land use is a fundamental resource for the agricultural development of oases in arid regions and is important for regional socio-economic development and ecological conservation. Using cultivated land use data from 85 counties in Xinjiang, China, from 2014 to 2021, this study employed the Super-SBM model, Moran’s I, and fixed-effects model to analyze the spatiotemporal evolution patterns and driving factors of ecological efficiency in cultivated land use in Xinjiang. The findings indicate that (1) The ecological efficiency of cultivated land use in Xinjiang was relatively low from 2014 to 2021 and showed a fluctuating upward trend, increasing by 17.02%. (2) The spatial distribution of high-high agglomeration areas in the ecological efficiency of cultivated land use in Xinjiang transitioned from a dual-core agglomeration to scattered distribution, while low-low agglomeration areas exhibited a pattern of initial agglomeration, followed by dispersion, and then re-agglomeration. (3) The rate of water and soil coordination, agricultural specialized services, per capita agricultural output value, mechanization level, and plastic film coverage rate are important factors that influence changes in the ecological efficiency of cultivated land use in Xinjiang. In the future, to enhance the ecological efficiency of cultivated land use in various counties of Xinjiang, attention should be paid to the coordination among various factors such as water resources, production technology, and economic level, which promotes the increase of cultivated land productivity while it reduced the negative externalities of cultivated land use.
