Coastal cities worldwide are grappling with the dual pressures of ecological degradation and the demand for high-quality tourism experiences. Dalian

a prominent coastal city in China

epitomizes this challenge

facing issues such as shoreline erosion

wetland degradation

and aesthetic homogenization of its cultural tourism landscapes. While existing research often addresses these problems through either a technical governance lens or a humanistic aesthetic critique

a significant theoretical gap exists in integrating these perspectives. This paper bridges this gap by proposing a novel synergistic framework that combines digital-intelligence

ecological governance

and aesthetic reconstruction. Methodologically

the study employs an interdisciplinary approach

integrating landscape ecology

scenes theory

and the philosophy of technology. The core argument is that the fusion of digital technologies (e.g.

digital twins

AI

IoT) with ecological principles and aesthetic strategies can foster a new paradigm for sustainable coastal development. The primary innovation lies in the construction of a "Digital-Ecological-Aesthetic" three-dimensional analytical model. This model provides an actionable pathway for transforming coastal landscapes from passive scenic backdrops into dynamic

resilient

and culturally resonant ecosystems. Ultimately

this research offers a replicable strategy for Dalian and other similar coastal cities to achieve ecological restoration

enhance cultural identity

and create immersive tourism experiences in the digital era.
