Research On Exploration On Landscape Design Method Of Quarrying Wasteland Based On Darning Theory

Since the reform and opening up,under the background of decades of rapid urbanization,social development has an increasing demand for stone resources.In the process of full swing development,China has become one of the countries with the largest stone output and consumption in the world.Rapid urban construction has also brought a series of environmental problems.Quarries and wastelands have seriously damaged the ecological environment and stripped the surface,resulting in vegetation damage,soil erosion and natural landscape damage;Geological structure changes,causing landslide,collapse,debris flow and other geological disasters;The accumulation of quarrying waste will also cause secondary pollution of water source and atmosphere,and occupy a large number of land and resources.Based on the elaboration of the concept of Darning expounded by Colin Rowe in Collage City,this paper introduces the darning theory into the landscape reconstruction of quarrying wasteland.Through the comparison of practice at home and abroad,this paper analyzes the landscape elements of quarrying wasteland from three aspects:natural conditions,spatial form,history and humanities,and combs the main direction of the transformation and utilization of quarrying wasteland at home and abroad.Through field investigation and relevant data retrieval and analysis,the author concludes that there are three problems in the transformation and utilization of quarrying wasteland in China: first,blind artificial greening and disrespect for the objective natural law;Second,ignore the landscape resources and destroy the characteristic spatial form of the site;Third,ignoring human history leads to the loss of regional characteristics of wasteland landscape;Guided by the problem,this paper puts forward three design methods to explore and solve the problem,that is,reconstructing the ecological environment through "ecological patching";Update the space function through "space patching";Inheriting humanistic history through "cultural darning".Finally,taking "Chongqing Youfang village mine pit landscape design" as an example,this paper solves the problems existing in the current stage of quarry wasteland reconstruction from multi-dimensional,multi-level and multi-directional,further expounds and confirms the application of design techniques based on darning theory,and makes a beneficial exploration and attempt for the theoretical innovation of quarry wasteland reconstruction.
