| 摘 要: 地理信息系统是研究空间位置及空间关系的学科，基础理论发展成熟，在各行各业应用广泛。不过现有的地理信息系统主要应用于大中尺度，小尺度研究很少，还没有对植物、动物及人体内部空间等微观尺度的相关描述。本文以植物营养学思想为基础，以植物内部空间的养分管理为目的，从空间认知、数学分析和数据管理三个方面构建了微观地理信息系统的框架，期望能为微观地理信息系统的研究提供思路与方法。 |

| Abstract: Geographical Information System (GIS) is a discipline that studies spatial locations and spatial relationships. Its basic theories are mature and widely used in all walks of life. However, the existing geographic information systems are mainly used in large and medium scales, with little research on small scales. There is no relevant description of microscopic scales such as plants, animals, and the internal space of the human body. Based on the idea of plant nutrition and the purpose of nutrient management in the internal space of plants, this paper proposes to build a framework of the micro-geographic information system from three aspects: spatial cognition, mathematical analysis and data management. It is expected to provide ideas and methods for the research of micro-geographic information system. |
