摘　　要：【目的】为摸清不同来源复垦复耕新增耕地农业生产符合性指标,分析其主要障碍因子,保障占补平衡工作真正实现“占优补优”,促进区域耕地质量的保护与提升。【方法】本研究以北京市3区共1113个新增耕地地块为研究对象,基于经典统计学方法研究了6类不同来源新增耕地农业生产符合性相关指标特征。【结果】(1)研究区各地块碎屑物含量、地形坡度、土层厚度、田间灌溉能力均达标;土壤容重和pH的变异系数较低,土壤有机质含量变异系数较高。(2)研究区土壤pH整体呈碱性,高于常规耕地;不同区中,顺义区土壤容重最高,大兴区最低;不同原利用类型中,耕地、园地和林地的土壤容重均值最小,草地和公共用地的耕土壤容重均值最大;大兴区与昌平区土壤有机质含量相对较低,顺义区土壤有机质含量较高。【结论】复垦复耕新增耕地因受不同区和原用地类型的影响,农业生产指标存在一定程度的差异,北京市应按不同区县与不同新增耕地来源制定相应的耕地质量提升方案。[Objective]The aims were to identify the agricultural production compliance and environmental quality indicators of new farmland from different sources of reclamation and replanting,and to analyze the main obstacle factors,so as to ensure that the work of balancing the occupation and replenishment of farmland,to realize"occupying and replenishing the best",to promote the protection and enhancement of the quality of regional farmland.[Method]A total of 1113 new farmland plots in three districts of Beijing were used to characterize the agricultural production attributes of six types of new farmland from different sources,and the indicators related environmental quality and potential ecological risk were assessed based on classical statistical methods.[Result]①The debris content,topographic slope,soil thickness and field irrigation capacity of all plots in the study area met the standards.The coefficients of variation of soil bulk density and pH were low,and the coefficients of variation of soil organic matter content were high.②The overall soil pH in the study area was alkaline and higher than that of conventional cropland.Among the different areas,soil bulk density was the highest in Shunyi District and the lowest in Daxing District.Among the different types of in situ land use,the mean value of soil bulk density was the smallest in arable land,garden land and forest land,and the mean value of soil bulk density was the largest in cultivated soil of grassland and public land.Soil organic matter content was relatively low in Daxing and Changping Districts,and higher in Shunyi District.[Conclusion]The obstacle factors of new farmland from different sources of reclamation and plowing needed to be categorized to carry out the technical work of upgrading the quality of farmland.
