    2000-2020年湖北省耕地利用集约化和规模化耦合协调特征

    Coupling coordination characteristics of arable land intensification and large-scale utilization in Hubei Province in 2000-2020

    • 摘要: 耕地资源的集约化和规模化是表征耕地利用效率的重要指标,对于确保中国粮食安全和促进农业可持续发展具有重要意义。该研究以湖北省为研究区,构建集约化与规模化评估指标体系及综合评估方法,并在县域尺度上研究了湖北省2000-2020年间耕地两化水平及其耦合协调模式。结果表明:湖北省耕地集约化水平呈中部高–东西低的整体提升时空格局,而规模化水平呈南高北低–中部高东西低的先降后升时空格局,集约化和规模化水平耦合协调度基本呈中部高–四周低的空间分布模式。尽管20 a间全省的耦合协调度指数持续提升,但仍有21%的县市处于轻度失调模式。规模化程度较低是造成耦合度失调的主要因素,需要做到因地制宜,促进区域协调发展。该研究结果可为湖北省调整农业产业结构的优化途径、保障粮食安全、探寻未来耕地集约化和规模化发展新模式提供理论支撑和决策服务。

       

      Abstract: Intensification and large-scale utilization of arable land are important indicators to assess the efficiency of arable land use. It is essential to sustain national food security and sustainable agricultural development in China. Taking Hubei Province of China as the study region, this study aims to investigate the overall utilization pattern of regional cropland resources over the last two decades. The spatial patterns were also analyzed to investigate the coupling coordination characteristics for arable land intensification and large-scale utilization. Firstly, an evaluation index system was built under the intensification and large-scale utilization, according to the theory of intensive utilization and landscape pattern. Agricultural statistics and remote sensing land cover datasets were selected to calculate the intensification level and large-scale utilization level at the county scale. Secondly, the spatial and temporal patterns were analyzed under the arable land intensification and large-scale utilization. Lastly, the coupling relationship model was conducted to investigate the coupling coordination characteristics of arable land intensification and large-scale utilization from 2000 to 2020. It was found that: 1) There was a high arable land intensification in the central part of the study area, but low in the east and west, with the overall score increasing from 0.23 in 2000 to 0.32 in 2020. The important factors were determined as the input and utilization intensity, leading to the improved level of the arable land intensification. Some suggestion was also proposed to optimize the existing intensive utilization. Much attention can be paid to the intensive development level of the Shennongjia forest area and Changyang County. 2) The large-scale utilization of arable land was high in the south, but low in the north, whereas, high in the middle, but low in the east and west. The overall score decreased from 0.31 in 2000 to 0.29 in 2010, and then increased to 0.30 in 2020. The decrease in the size and shape of the plaque was the main factor in the decline. The majority of counties in the western mountains showed an increasing trend in the large-scale utilization level from 2000 to 2020, while the majority of counties in the eastern showed a decreasing pattern. It was recommended to focus on the integration of the cultivated land resources in the mountain or hilly areas in the eastern and western. 3) The coupling coordination between the intensification and large-scale utilization was high in the middle, but low in the surrounding area, indicating the increase from 2000 to 2020. The proportion of counties with coordinated development increased from 49% to 55%. However, 21% of counties and cities were still in the mild imbalance level in 2020. These counties and cities (e.g., Suizhou City, Guangshui City, and Luotian County) presented a low large-scale utilization level, but relatively high intensification level, leading to the imbalance of the coupling degree. It is necessary to fully meet the local conditions for better coordinated regional development. The spatial and temporal characteristics of arable land intensification and large-scale utilization can provide theoretical support and decision-making services for the structural adjustment of cultivated land utilization, efficient utilization of agricultural resources, and sustainable development. The finding can provide guidance for the new modes of future arable land intensive and large-scale development.
