摘要: 构建动态当量调节因子模型测算2005~2022年中国31个省份的农业生态系统服务价值,综合使用Dagum基尼系数、核密度估计、马尔可夫链及地理探测器等方法,探究农业生态系统服务价值的时空演化特征及其驱动因素。研究发现:(1)时间维度上,2005~2022年中国农业生态系统服务价值总体呈现波动上升趋势;空间维度上,农业生态系统服务价值呈现“南高北低、东高西低”的阶梯型特征。(2)中国农业生态系统服务价值总体差异呈现“U”型演变趋势,超变密度是总体差异的主要来源,区域间差异次之,区域内差异的贡献率最低。考察期内地区非均衡性明显增大,两极分化趋势明显,且内部流动性较弱。(3)自然地理因素对农业生态系统服务价值时空演化的驱动作用强于经济社会因素。降水量是影响农业生态系统服务价值时空演化的主导因素,降水量和人均GDP的交互组合是关键性驱动因素。

Abstract: A dynamic equivalent regulatory factor model was constructed to estimate the value of agroecosystem services in 31 provinces of China from 2005 to 2022. The Dagum Gini coefficient, kernel density estimation, Markov chain and geodetector methods were comprehensively used to explore the spatio-temporal evolution of agroecosystem services value and the associated driving factors. The results showed that: (1) China's agro-ecosystem services value generally exhibited a fluctuating upward trend from 2005 to 2022. In terms of the spatial distribution, China's agro-ecosystem services value displayed a ladder-type characteristic of “high in the south and low in the north, high in the east and low in the west”. (2) The overall difference in the agro-ecosystem services demonstrated a U-shaped evolutionary trend of fluctuation, with hypervariable density being the primary source of the overall difference, followed by inter-regional differences, and intra-regional differences having the lowest contribution rate. During the study period, regional imbalance increased significantly, polarization trends were evident, and internal mobility remained weak. (3) Natural geographic factors drove the spatio-temporal evolution of the agroecosystem services more strongly than the economic and social factors. Precipitation was the dominant factor that influenced the spatial and temporal evolution of the agroecosystem services, and the interactive combination of precipitation and GDP per capita was the key driver.
