摘要：Metamaterial refers to artificial composite materials that exhibit extraordinary physical properties that are not found in natural materials. The extraordinary characteristics of metamaterials are derived from the physical response caused by artificially prepared, special non-uniform intercalated structures. Under the rapid development of society and the continuous advancement and development of science and technology, GIS and GPS GIS technology as spatial information analysis technology has begun to develop rapidly and widely. The frequency response characteristics of metamaterials can be adjusted in a wide range according to their structural parameters, so we can design them to work in the frequency range we need through the basic unit structure parameters of metamaterials. Compared with the existing information management methods, the introduction and application of geographic information system technology can provide strong spatial data processing, analysis, query and maintenance capabilities for afforestation project management, and can provide an effective working platform and modern information technology support for obtaining information and decision analysis in the management process of forestry major ecological engineering projects. Based on metamaterials, starting from the advantages of GIS, this paper focuses on analyzing the specific application of GIS in forestry engineering planning and design, and systematically introduces GIS software application technology. To realize the digitalization and networking of forestry projects so as to play a more active role in improving the modern management level of forestry ecological projects in China through the application and demonstration of high and new technologies.
