- Abstract:
- According to the natural ecological characteristics of mountainous cities, this study employs systematic territorial spatial planning thinking, based on macro, meso, and micro perspectives, and integrates three fundamental disciplines: ecology, environment, and safety. Grounded in the three spatial levels of soil and water—water and city—water systems, it constructs an evaluation method for water ecological security in the territorial space of mountainous cities. The research clarifies the ecological coupling relationships among mountains, water, and cities, anchors three core functions: integrated soil-water control, harmonious water-city integration, and coordinated water system interaction, and aligns with four major requirements: ecological civilization, environmental friendliness, safety resilience, and suitability for mountainous areas. Focusing on six ecological dimensions-source, barrier, city, shore, system, and flow—and centering on twelve water-related actions—water conservation and nurturing, water retention and protection, water circulation and management, water maintenance and treatment, water drainage and guidance, and water revitalization and purification, this study establishes a water ecological security evaluation system for mountainous cities’ territorial space, characterized by “three levels, four attributes, six dimensions, and twelve actions”. Through empirical research on typical mountainous cities, it proposes that “soil and water” serve as a crucial barrier for maintaining water ecological security in mountainous areas, “water and city” represent a critical link constraining water ecological security, and “water systems” constitute the lifeline for sustaining water ecological security. It emphasizes the need for hierarchical risk assessment of “soil and water”, “water and city”, and “water systems”, with tailored measures based on local conditions and water-specific strategies.
