Abstract:With the growing confidence in our culture, the influence of regional resources and cultural characteristics on landscape design is becoming increasingly profound. The concept of in situ' is an important way to stimulate regional advantages. This article examines a case study of the Green and Beautiful Guangdong Species Exhibition Garden in the South China National Botanical Garden. It explores the application of the landscape construction framework of 'cognition-intervention-transformation'. Through the idea of 'integrating three aspects', it recognizes the characteristics of natural landscape elements and historical context elements. By aligning with the contemporary needs of introducing nature education, integrating the site's internal resources, and displaying symbolic green and beautiful plants, these elements are implemented and transformed into practical strategies for garden landscape construction. From the perspective of the integrated development of ecology, culture, and garden scenery, four construction strategies are constructed, namely, sorting out the spatial layout, symbiosis with the natural environment, continuing the historical context, adopting a cost-saving gardening style, and applying local materials. This elaborates on applying the 'in situ' concept in the practice of the exhibition garden, providing a reference for creating garden landscapes with regional characteristics.
