摘　　要：科学测度耕地多功能权衡与协同关系对于量化和表征耕地隐性形态具有重要意义,可为构建土地利用绿色转型调控路径、揭示人地关系演化过程提供科学依据。该研究以黄河流域(河南段)为研究区域,利用1990-2020年时间序列社会经济发展数据,从耕地的生产、社会、生态以及文化功能4个维度系统构建耕地多功能评价指标体系及土地系统功能权衡度(Land system Function Trade-off Degree,LFTD)模型,测算黄河流域(河南段)耕地多功能指数,解析耕地多功能之间权衡与协同关系时序演化特征,以此揭示耕地利用隐性形态的演变规律。结果表明:1)1990-2020年间黄河流域(河南段)耕地的生产、社会、生态和文化功能均呈增长态势,且生产与文化功能增长较为突出。2)按照功能层次性,将1990-2020年间耕地多功能的变化划分为6个阶段。在1990-2010年的前四个阶段中以生产与生态功能为主,在2010-2020年的后两个阶段中以生产与文化功能为主,并且功能间作用关系较为复杂。3)1990-2020年间,耕地生产、社会、生态和文化功能间相互作用关系呈现“权衡为主导-权衡协同持平-权衡为主导”的演化特征,黄河流域(河南段)耕地功能于2010年后呈现显著转型特征。4)耕地转型影响因素关联性随时间变化而不同。1990-2020年影响因素关联性变化显示:城镇化率、农业机械总动力、粮食总产量、第三产业占比是显著影响因素。耕地隐性形态变化可深层次显化耕地利用转型,为耕地可持续利用提供参考。Multi-functional trade-off and synergy of cultivated land can be accurately quantified to characterize the hidden form of cultivated land.In this study,the multi-functional analytical framework was constructed to evaluate the functional classification of cultivated land in the Yellow River Basin(Henan section)using the time series social and economic development data from 1990 to 2020.The function of cultivated land was firstly divided into the production,social,ecological,and cultural function.The multi-functional index of cultivated land was then calculated to reveal the multi-functionality evolution of cultivated land.The dominant function was clarified for the cultivated land at different stages of transformation.After that,a land system function trade-off degree(LFTD)model was selected for the trade-off and collaborative analysis.As such,the hidden form of cultivated land use was determined to explore the complex evolution and influence mechanism of cultivated land multi-function in the process of cultivated land transformation.The results showed that:1)The multi-function of cultivated land showed a fluctuating upward trend from 1990 to 2020.Specifically,the production function of cultivated land continued to increase,due to the ever-increasing yield level of grain crops and the total power of agricultural machinery.The social function index of cultivated land also increased slightly with the increase of per capita net income of farmers.Nevertheless,a downward trend was found in the ecological function index of cultivated land,particularly for the use of chemical fertilizers after 2010.Fortunately,the cultural function of cultivated land increased significantly with the increase of cultural investment and agricultural sightseeing garden area.2)Six stages were divided for the variation in the multifunctionality of cultivated land from 1990 to 2020,according to the functional hierarchy.The production and ecological functions were dominated in the first four stages of 1990-2010,while the production and cultural
