农业农村空间生态修复质量测算方法研究——以辽宁省凤城市为实证

Research on the Method of Measuring the Ecological Restoration Quality in Agricultural and Rural Spaces-An Empirical Evidence from Fengcheng City,Liaoning Province

文章在探讨当前国土空间生态修复内涵与进展的基础上,参考文献计量分析与政策分析结果,结合土地碳汇模型,构建了基于“比重法-均方差法”的农业农村空间生态修复质量测算方法,包括庭院空间生态、生态农业空间质量、农村空间生态改建、农业空间生态恢复4个维度、19项具体指标,并以辽宁省凤城市为实证对象,对该测算方法的有效性进行检验。基于实证分析做出的问题识别,提出凤城市农业农村空间生态修复的对策:(1)庭院空间生态保护修复:开展全域土地综合整治,实施农用地、建设用地整理等;(2)生态农业空间质量保护修复:实施野生动植物种群保护恢复、生物多样性保护、人工商品林建设等;(3)农村空间生态改建修复:实施生态基础和生态网络建设,提升农村生态系统质量和稳定性;(4)农业空间生态恢复修复:大力实施“固碳工程”,推进碳汇交易,探索拓展场外交易渠道。

Based on discussing the connotation and progress of the ecological restoration of national land space,with reference to the results of bibliometric analysis and policy analysis in the literature,and combined with the land carbon sink model,the paper constructed a method of measuring the quality of ecological restoration of agricultural and rural space based on the"specific gravity method and mean-variance method".The measuring method includes four dimensions and 19 specific indicators,including courtyard space ecology,ecological quality of agricultural space,ecological reconstruction of rural space,and ecological restoration of agricultural space.The validity of the measurement method is tested with the empirical object of Fengcheng city,Liaoning province.Based on the problem identification made by the empirical analysis,countermeasures for agricultural and rural space ecological restoration in Fengcheng city were proposed:①Ecological protection and restoration of courtyard space:carry out comprehensive land improvement in the whole area,carry out agricultural land and construction land consolidation.②Ecological agricultural space quality protection and restoration:carry out wildlife protection and restoration,biodiversity protection,and artificial commercial forest construction.③Rural spatial ecological transformation and restoration:carry out ecological foundation and ecological network construction,and improve the quality and stability of rural ecosystems.④Agricultural spatial ecological restoration and repair:vigorously implement the"carbon sequestration project",promote carbon trading,and explore the expansion of off-site trading channels.
