Under the background of urban low-carbon transformation, a study on regionalization can provide a refe-rence for achieving optimization of territorial protection and high-quality development. We examined carbon emission and spatial differentiation characteristics of land use in 79 counties of Fujian Province. From the perspective of carbon neutral, reasonable division of region of Fujian Province was gotten after a comprehensive evaluation combined with economy contributive coefficient of carbon emission, ecological support coefficient of carbon absorption and priority function zoning. Then, we proposed the low-carbon optimization strategy for differentiated land space. The results showed that the total carbon emission in Fujian Province was 62.0416 million t and the total carbon absorption was 49.0971 million t in 2017, indicating that Fujian was at a state of carbon deficit. The spatial distribution of carbon emission and carbon absorption was opposite from coastal to inland. The six territorial space zones were low-carbon development-ecological function zone, low-carbon development-main producing area of agricultural products zone, low-carbon development-urban optimization zone, carbon sink function-main producing area of agricultural products zone, carbon intensity control-urban optimization zone, and high-carbon optimization-urban optimization zone. We proposed the corresponding low-carbon optimization strategies of territorial space for each zone.
在城市低碳转型背景下，开展区域划分研究可为实现国土空间保护优化和高质量发展提供参考。我们考察了福建省79个县土地利用的碳排放及空间分异特征。从碳中和角度，结合碳排放经济贡献系数、碳吸收生态支撑系数和主体功能区划分，综合评价后对福建省进行合理分区。进而提出差异化土地空间的低碳优化策略。结果表明，2017年福建省碳排放总量为6204.16万吨，碳吸收总量为4909.71万吨，表明福建处于碳亏缺状态。碳排放与碳吸收的空间分布呈沿海向内陆相反态势。六大国土空间分区分别为低碳发展—生态功能区、低碳发展—农产品主产区、低碳发展—城镇优化区、碳汇功能—农产品主产区、碳强度控制—城镇优化区、高碳优化—城镇优化区。我们针对各分区提出了相应的国土空间低碳优化策略。
