摘要
从粮食安全视角出发,在理论分析的基础上,运用基于碳足迹和产量因子修正的生态足迹模型,结合生态服务价值,量化2011—2018年东北黑土区部分城市的耕地生态补偿标准和迫切程度。结果发现:在粮食安全视角下,研究区均为耕地生态盈余区,约有54.1%的耕地生态承载的粮食产量供给到了耕地生态赤字区。受耕地生态盈余面积、单位耕地生态服务非市场价值和支付能力影响,研究区内各市的耕地生态补偿标准总量在研究期初有所提高,但随后均出现明显降低趋势,2018年的耕地生态补偿标准分别为哈尔滨市19.50亿元、绥化市23.60亿元、大庆市10.95亿元、长春市13.05亿元、四平市25.95亿元、铁岭市9.19亿元。考虑各市的经济发展水平,应当率先向四平市、绥化市支付耕地生态补偿。
Black soil resources are the cornerstone of the comprehensive grain production capacity in northeast China.From the perspective of food security,on the basis of theoretical analysis,the ecological footprint model based on carbon footprint and yield factor correction was adopted,combined with the ecosystem service value,to quantify the ecological compensation standard of cultivated land and the urgency of some cities in black soil region in northeast China from 2011 to 2018.It is shown that the study area is the ecological surplus area of the cultivated land under food security,and 54.1% of the grain output carried by cultivated land is supplied to the ecological deficit areas in China.The compensation standards in 2018 should be Harbin 1.95 billion yuan,Suihua 2.36 billion yuan,Daqing 1.095 billion yuan,Changchun 1.305 billion yuan,Siping 2.595 billion yuan,Tieling 919 million yuan.By considering the economic development level of each city,Siping City and Suihua City have the highest priority in ecological compensation.
