Quality Evaluation and Analysis of Ecological Landscape for Lattice Beam Slopes in Shenzhen

There is a lack of targeted comprehensive evaluation systems for the ecological landscapes of grid beam slopes in South China, and existing evaluation methods are difficult to match the regional ecological restoration characteristics and engineering practice requirements.This study takes the lattice beam slopes in Shenzhen as the research object and constructs a comprehensive quality evaluation system consisting of 5 criterion layers (i.e., protection, ecology, landscape, functionality and economy) and 21 specific indicators based on the Analytic Hierarchy Process (AHP). Furthermore, the fuzzy comprehensive evaluation method is adopted to conduct an empirical evaluation on the typical lattice beam slopes of Shenzhen City Polytechnic. The weights of each criterion layer are determined by the Yaahp software, with the weights ranked from high to low as protection (0.5697), ecology (0.1776), economy (0.1061), functionality (0.0853) and landscape (0.0613). At the indicator layer, structural stability (0.2516) and soil and water conservation (0.0672) are identified as the core key indicators of each criterion layer. The results of the empirical evaluation show that the overall score of the ecological landscape of the slopes in Shenzhen City Polytechnic reaches 4.47 points, which is comprehensively rated as an excellent grade. Among the criterion layers, protection obtains the highest score (4.63 points), while economy gets a relatively lower score (4.03 points). The evaluation results are highly consistent with the on-site actual conditions. The study indicates that the constructed evaluation system is both scientific and operable, which can effectively reflect the actual construction status of the ecological landscape of lattice beam slopes in Shenzhen, and provide a quantitative evaluation basis and practical reference for the planning, construction, and management of the ecological landscape of lattice beam slopes in southern China.
