Abstract

Coastal cities, due to their concentration of economic activities, have been crucial habitats for neighboring maritime nations, often characterized by high population densities. The livelihoods of residents in these cities have consistently been influenced by economic, social, cultural, and environmental conditions. Therefore, this research aimed to assess the spatial biodiversity of coastal areas in Bushehr Province using a regional planning approach. The study was applied in terms of its objective (strategic developmental) and descriptive-analytical in nature and methodology, employing an inductive approach. To answer the research question, 11 indicators including temperature, slope, distance from roads, precipitation, distance from drainage, land use, distance from the epicenter of land subsidence, distance from fault lines, elevation, distance from the coast, and distance from the city in terms of sustainable development were utilized, employing the AHP method and ArcGIS software. The results indicated that generally, as we move closer to the coastline, the environmental conditions become more restricted. Key factors contributing to this situation include inappropriate slope, high temperature and humidity, low precipitation, presence of wetlands, sand dunes, rocks, saltwater lakes, and salt marshes, among others, which have adversely affected the environmental conditions. On the other hand, areas with favorable biodiversity conditions are more concentrated in the southeast, attributed mainly to suitable climatic conditions (temperature and precipitation), better elevation and slope, presence of vegetation, forests, and suitable conditions for agriculture.

Highlights

  • As we move closer to the coastline, environmental conditions in the area become more constrained.
  • The concentration of areas with favorable and suitable biodiversity conditions is higher in the southeast of the region.
  • To answer the research question, 11 indicators were utilized, including temperature, slope, distance from roads, precipitation, distance from drainage, land use, distance from the epicenter of land subsidence, distance from fault lines, elevation, distance from the coast, and distance from the city.
