A STUDY ON THE PERCEPTION AND EVALUATION OF URBAN HERITAGE VALUE AND ITS PRACTICAL CONDUCTION PATH BASED ON HUL THEORY--TAKING THE OLD TOWN OF MAANSHAN AS AN EXAMPLE

Resource-based industrial cities have formed urban heritage deeply coupled with resource endowment in the course of evolution, which plays an irreplaceable role in maintaining the integrity of urban landscape and cultural continuity. At the stage when China's urban development has shifted from incremental expansion to stock tapping, how to scientifically assess the diversified values of urban heritage, to solve the real conflicts such as “lack of protection, dissolution of characteristics, and faulty memories”, and to balance the relationship between heritage protection and urban development have become the focus of attention for the sustainable development of resource-based industrial cities. The Historic Townscape (HUL) approach regards urban development as a whole, and considers that the dynamic superposition of history and current development, and continuous changes are important parts of urban tradition. This paper takes the old city of Maanshan as the research object, uses the HUL theory to analyze the current situation of urban evolution and development, assesses the value elements, and proposes a path for the transmission of urban heritage value to provide a sample for the practical application of the HUL theory in the conservation of resource-based industrial cities. The thesis is divided into six chapters. Chapter 1 introduces the research background and related concepts, and establishes the research framework based on the literature review of domestic and international research status. The second chapter elaborates the connotation, development history and methodology of HUL theory, and summarizes its practical experience in urban heritage conservation and inheritance. Then we take the old city of Maanshan as an object, introduce HUL theory, and construct the research framework of “cognition-evaluation-conduction”. In Chapter 3, the dynamic layering process of the old urban area is systematically sorted out, and the three core carriers of natural environment elements, intangible elements and material elements are identified. Chapter 4 establishes an evaluation system for the value of Maanshan's urban heritage, and quantitatively evaluates the value elements through questionnaire research, field visits and public data acquisition. Based on the evaluation results, Chapter 5 proposes a living urban heritage practice conduction path: restoration and manifestation of landscape landscape, inheritance and display of history and culture, and renewal of land parcels under the premise of both protection and development. The paper studies the urban value evaluation and conduction path based on HUL theory, establishes a quantitative evaluation system, and provides an exploration of heritage protection and conduction in resource-based industrial cities.
