摘要:

深入研究耕地利用形态对实现耕地高效利用、保障粮食供应具有重要意义。构建耕地利用形态综合评价指标体系,运用时空统计方法,探讨2010—2021年中国西北农作制区耕地利用“显-隐性”形态耦合协调度的时空演化特征,并运用障碍度分解模型分析耕地利用的障碍指标。结果表明:(1)中国西北农作制区耕地利用显性、隐性形态存在不同步发展,滞后发展区域分异特征显著;耕地利用“显-隐性”形态耦合协调度水平不高,各亚区均存在明显的极化分布特征。(2)耕地利用“显-隐性”形态耦合协调度区域内差异呈波动下降趋势,区域间差异贡献率逐渐上升成为总体差异的首要来源,各亚区均存在空间收敛特征。(3)耕地利用主要受到耕地数量结构、景观特征、集约化水平以及生产功能等因素限制。将上述因素作为关键瞄准,应提高水资源的合理运用、推进适宜性耕地的保护开发、缓解障碍指标的掣肘,促进耕地利用“显-隐性”形态耦合发展,以期为中国西北农作制区耕地利用的可持续发展提供合理的科学参考。

Abstract:

Studying cropland utilization patterns is crucial for achieving efficient cropland use and ensuring food security. This study explores the spatiotemporal evolution characteristics of the “explicit-implicit” patterns coupling coordination degree of cropland utilization in the farming regions of northwest China from 2010 to 2021. A comprehensive evaluation index system of cropland utilization patterns was constructed, and spatiotemporal statistical methods were employed. The obstacle factors of cropland utilization were analyzed using the barrier degree decomposition model. The results showed that: (1) The explicit and implicit patterns of cropland utilization in northwest China’s farming systems developed asynchronously, with significant regional differentiation and backward development. The coupling coordination degree between explicit and implicit patterns of cropland utilization remained low, exhibiting a pronounced polarization in each sub-region. (2) The intra-regional differences in the coupling coordination degree of “explicit-implicit” patterns of cropland utilization displayed a fluctuating downward trend, while the contribution rate of inter-regional differences gradually increased, becoming the main source of overall variation. Each sub-region demonstrated spatial convergence characteristics. (3) Cropland utilization is primarily constrained by factors such as cropland quantity structure, landscape characteristics, intensive level, and production function. To address these limitations, the study suggests improving the rational use of water resources, promoting the protection and development of suitable cultivated land, and alleviating the impact of obstacle factors. These measures aim to develop a suitable farming system and enhance the coupling development of “explicit-implicit” patterns of cropland utilization, providing a scientific reference for the sustainable development of cropland utilization in the farming systems of northwest China.
