Abstract

Ecological compensation for cultivated land is a prominent means to coordinate the protection and utilization of cultivated land ecosystems. This study assessed the ecological compensation for cultivated land, considering both the ecological footprint and value of ecosystem services. We used the ecological footprint model to calculate the ecological footprint and ecological carrying capacity of cultivated land, combined with the value of its ecosystem services, with a focus on estimating its ecological compensation standard, and we analyzed the temporal and spatial distribution characteristics of Northeast China. We found that the ecological footprint and ecological carrying capacity of cultivated land showed a fluctuating growth trend in Northeast China from 2000 to 2020, increasing by 288.83 × 105 ha and 131.37 × 105 ha, respectively. The spatial distribution of cultivated land’s ecological footprint and ecological carrying capacity showed growth from the southwest to the northeast. The value of its ecosystem services presented an overall trend of growth over the past 20 years, increasing by CNY 13.64 billion, or an increase of 12.47%. In terms of spatial distribution, the trends of the ecological compensation for cultivated land showed obvious differences. This study mainly focused on black soil cultivated land, and its results are helpful for governments in different countries solving similar problems in terms of the ecological compensation for cultivated land. This study will provide a valuable reference to measure the compensation standard scientifically and to provide policy recommendations for sustainable cultivated land’s protection and utilization.

中国东北地区耕地生态补偿的时空分析

耕地生态补偿是协调耕地生态系统保护与利用的重要手段。本研究从生态足迹和生态系统服务价值两个方面对耕地生态补偿进行了评估。我们利用生态足迹模型计算了耕地的生态足迹和生态承载力，结合其生态系统服务价值，重点估算了其生态补偿标准，并分析了中国东北地区的时空分布特征。我们发现，2000-2020 年东北地区耕地生态足迹和生态承载力呈波动增长趋势，分别增加了 288.83×105 公顷和 131.37×105 公顷。耕地生态足迹和生态承载力的空间分布呈现由西南向东北增长的趋势。近 20 年来，耕地生态系统服务价值总体呈增长趋势，增加了 136.4 亿元人民币，增幅为 12.47%。从空间分布来看，耕地生态补偿的变化趋势存在明显差异。本研究主要以黑土耕地为研究对象，研究结果有助于各国政府解决类似的耕地生态补偿问题。本研究将为科学衡量补偿标准提供有价值的参考，并为耕地的可持续保护和利用提供政策建议。
