Landscape Design of Zones with Large-Scale Warehouse and Industrial Development Located in Peri-Urban Areas Using Sectoral Analysis of Landscape Interior (SALI)-A Case Study of Wroclaw, Poland

Suburban areas are often used for large-scale developments such as hypermarkets, warehouses, and logistics zones, which lead to the fragmentation of natural areas and the visual degradation of the landscape. This study aimed to evaluate ways to reduce the negative impact of these developments by introducing green infrastructure (GI) elements. The analysis focused on warehouses in the inner ring of the planned green infrastructure system in the Wroc & lstrok;aw Functional Area (GI WFA). This study involved three stages: (1) selecting a landscape-functional unit (LaFU) vulnerable to landscape degradation; (2) analyzing changes from the development of large-scale warehouses between 2004 and 2021; and (3) assessing the effect of new GI elements using the Sectoral Landscape Interior Analysis (SALI) method. Three models of GI implementation were proposed and evaluated both from a plan view and from a moving observer's perspective. The results showed that large-scale developments reduce biologically active areas and disrupt landscape harmony. Model III, which includes green roofs, trees, and semi-permeable surfaces, significantly increased greenery and reduced visual degradation. It is recommended to apply the model and its variations in other similar developments for the benefit of the natural environment and landscape.
