Creative Strategies to Recover Urban Land in Disuse

Abstract

[eng] Industrial land in disuse is a dual carrier of crisis and revitalization of mining cities facing decline. On the one hand, it is an object that carries urban crisis, which has many negative effects on the urban environment, economy, and society. On the other hand, it has the advantage of reuse and can be transformed into a positive factor for urban revival. The main starting point of this research is to explore the value of industrial wastelands and their reuse to promote China's mining cities out of their difficulties.

The existing research on industrial lands in disuse lacks a holistic and systematic view and has insufficient knowledge of overall value of industrial lands in disuse and inadequate refining of their core values. This has led to a series of problems such as "islanding" renewal, "destructive" protection, and convergence of appearance. On account of these problems, this research applies landscape genetic theory to the conservation and renewal of industrial lands in disuse by using literature research, field survey, typology, comparative study, and systematic analysis, and analyzes the regular characteristics of industrial land in disuse clusters in China in time and space, so as to explore a more effective way for the deep excavation and scientific expression of the value of industrial lands in disuse. This research is highly interdisciplinary and exploratory. The main research contents and academic contributions:

1. The research introduces the concept of genes in biogenetics, based on the principles of "base pairing" and "DNA sequence combination" in the storage and transmission of genetic information. And based on the typology and the epistemology that interprets anthropology and the methodological basis of designing language and semiotics, we have constructed a landscape genetic theory structure with a landscape gene structure system and landscape genetic atlas as the core.

2. This research unravels the mining cities in China as the research background, clarifies the definition, classification, regional distribution, and spatial structure of mining cities, discusses the characteristics and laws of the formation and development of mining cities, and summarizes the problems and countermeasures. Then, the concept of industrial land in disuse is proposed. Its causes are analyzed and classified, and the main problems in the protection and renewal of industrial lands in disuse in China are analyzed.

3. Based on the evaluation of the value of industrial lands in disuse and their morphological and structural laws, the "unit-piece-chain-domain" landscape genetic structure system is proposed, so that any complex industrial land in disuse group can be quickly decomposed and combined under the guidance of this system. Based on this structure system, coupling mining city spaces, industrial land in disuse groups, and green space, the effective way for transformation and characteristics shaping of mining city and high-quality human living environment construction is explored.

4. This research proposes a conservation method and creative strategy for industrial land in disuse based on the genetic behavior of landscape genes. In the gene replication stage, it focuses on the protection of the authenticity and integrity of the landscape genes of industrial wasteland. In the gene translation stage, it focuses on the benign recombination and functional grafting of the landscape genes of industrial land in disuse. Three creative strategies of recombination and grafting are proposed: landscape genetic juxtaposition, landscape genetic translation, and landscape genetic symbiosis. The space of industrial land in disuse, which is contradictory and conflicting due to cultural heterogeneity and spatial and temporal differences, is reconstructed to create a landscape with regional characteristics.

Huangshi City is a representative mining city in China, with a large number and many types of industrial wastelands, which has temporal continuity and spatial integrity. Based on the evaluation of the value of industrial wastelands in Huangshi City, using landscape gene theory, this research constructs the landscape gene structure system of "unit-piece-chain-domain", and builds the spatial layout of coupling urban space, industrial land in disuse clusters, and green space. Taking Tonglvshan landscape gene piece and Hanyeping Railway landscape gene chain as examples, this research maps the landscape gene atlas. Based on the landscape gene atlas and genetic behavior, protection of authenticity and integrity, recombination, and grafting measures are proposed to revitalize industrial land in disuse.
