Land space is the carrier of human production, living activities, and ecological civilization construction. How to promote the orderly, moderate, and sustainable development and utilization of land space is a scientific problem to be solved. As a key element in China's spatial planning, the quantitative analysis of spatial pattern and functional zoning has become a focus of China's current development. Based on the analysis of land space symbiosis development, this study takes Henan province as the case study; appropriate indicators were selected from the perspective of "production-living-ecological" functions (PLEFs) index that was developed including three subsystems of the production function, living function, and ecological function. The entropy weight method and geographic information system (GIS) spatial method were used to analyze the PLEF status and spatial pattern in Henan province. The PLEF score showed a certain geographical pattern, where in the southwestern areas of Henan province have higher PLEFs than that in the northeastern areas. The PLEFs have an obvious positive correlation in the spatial distribution by spatial correlation analysis. In addition, this study designs a three-dimensional magic cube evaluation model to analyze the symbiotic function type of land space. The results indicated that the PLEFs of Henan province were classified into 13 symbiotic function types of areas, which can better reflect the spatial differentiation characteristics. Moreover, we proposed paths to promote the development and management of each type function area.
土地空间是人类生产、生活活动和生态文明建设的载体。如何促进土地空间的有序、适度、可持续发展和利用，是一个需要解决的科学问题。作为中国空间规划的关键要素，空间格局和功能分区的定量分析已成为当前中国发展的重点。本研究基于土地空间共生发展的分析，以河南省为例；从“生产-生活-生态”功能（PLEFs）指标的角度选择了适当的指标，该指标包括生产功能、生活功能和生态功能三个子系统。采用熵权法和地理信息系统（GIS）空间方法分析了河南省的 PLEF 状况和空间格局。PLEF 得分表现出一定的地理格局，其中河南省西南部的 PLEF 高于东北部。通过空间相关分析，PLEFs 的空间分布具有明显的正相关性。此外，本研究设计了一个三维魔方评价模型来分析土地空间的共生功能类型。结果表明，河南省的 PLEFs 被分为 13 种共生功能类型的区域，这可以更好地反映空间分异特征。此外，我们还提出了促进各类型功能区发展和管理的路径。
