Because of the trends in population growth and rapid industrialization and urbanization, the intensity and structure of land use are undergoing great changes. Henan Province is an important economic province and a major grain producing and energy consumption area, and its land use plays a key role in the sustainable development of the whole of China. This study takes Henan Province as the research object, selects panel statistical data from 2010 to 2020, and discusses the land use structure (LUS) in Henan Province in terms of three aspects: information entropy, analysis of land use dynamic change, and land type conversion matrix. Based on the indicator system "social economy (SE)-ecological environment (EE)-agricultural production (AP)-energy consumption (EC)", a land use performance (LUP) evaluation model was constructed to judge the performance of various land use types in Henan Province. Finally, the relational degree between LUS and LUP was calculated through the grey correlation. The results show that among the eight land use types in the study area since 2010, land used for water and water conservancy facilities increased by 4%. In addition, transport and garden land changed significantly, and was mainly converted from cultivated land (decreased by 6674 km) and other land. From the perspective of LUP, the increase in ecological environment performance is the most obvious, while agriculture performance is lagging behind; it is worth paying attention to the energy consumption performance, which is decreasing year by year. There is an obvious correlation between LUS and LUP. LUS in Henan Province presents a gradually stable state, and the transformation of land types promotes LUP. Proposing an effective and convenient evaluation method to explore the relationship between LUS and LUP is very beneficial in helping stakeholders to actively focus more on optimizing land resource management and decision making for the coordinated and sustainable development among agricultural, socio-economic, eco-environmental, and energy systems.
由于人口增长和快速工业化、城市化的趋势，土地利用的强度和结构正在发生巨大变化。河南省是中国重要的经济大省和粮食主产区、能源消耗区，其土地利用对全国的可持续发展起着关键作用。本研究以河南省为研究对象，选取 2010-2020 年面板统计数据，从信息熵、土地利用动态变化分析和土地类型转换矩阵三个方面探讨河南省土地利用结构（LUS）。基于“社会经济（SE）-生态环境（EE）-农业生产（AP）-能源消耗（EC）”指标体系，构建土地利用绩效（LUP）评价模型，判断河南省各类土地利用类型的绩效。最后，通过灰色关联计算 LUS 和 LUP 的关联度。结果表明，研究区 2010 年以来 8 种地类中，水域及水利设施用地增加了 4%。此外，交通和园林用地变化明显，主要由耕地（减少 6674km）和其他土地转化而来。从 LUP 来看，生态环境绩效的增长最为明显，而农业绩效则相对滞后；值得关注的是，能源消耗绩效逐年下降。LUS 与 LUP 之间存在明显的相关性。河南省 LUS 呈现逐渐稳定的状态，土地类型的转化促进了 LUP 的发展。提出一种有效便捷的评价方法，探讨 LUS 与 LUP 的关系，对于帮助利益相关者积极关注优化土地资源管理和决策，促进农业、社会经济、生态环境和能源系统之间的协调可持续发展具有重要意义。
