The Research Of A Landscape Ecological Restoration Strategy For Three-line Construction Industrial Sites Of Mianyang City

Mianyang is one of the important cities in China's industry during the Three-line Construction period.At present,a large number of industrial sites of Three-line Construction remain.These industrial sites are not only the memory of a specific historical period of the city,occupying an important position in the city,but their existence also brings a series of environmental,economic and social issues.With the renewal of urban industrial land,the protection of industrial heritage,and the restoration of urban ecology,the upgrading of industrial sites is imperative.The basis for the regeneration of sites are the improvement of the site environment.Therefore,landscape ecological restoration is an important means to realize the renewal of industrial sites and the sustainable development of the environment.Based on the principles of restoration ecology and landscape ecology,the researcher focuses on the ecological restoration of the Three-line Construction industrial sites in Mianyang.The main tasks are as follows:First of all,through the analysis of the connotation and extension of industrial sites,the Three-line Construction industrial sites,and the concept of landscape ecological restoration,and through the study of domestic and foreign cases in landscape ecological restoration of industrial sites,the researcher learns about ecological design strategies and ecological restoration methods.Besides,the researcher designs a research questionnaire according to theory that can be can be used in this study and the important factors can be extracted from the study.Secondly,taking the industrial sites of Three-line Construction in Mianyang as the main focus,and proceeding from the status quo of its space environment and the awareness of the crowds,the field survey and research on the landscape ecological environment were carried out.Thirdly,from the perspective of landscape ecological restoration,the evaluation indicators of landscape ecological environment and industrial heritage are summarized.Then the pattern of site landscape design is determined by comparison of indicators,and the appropriate landscape ecological design isproposed for different modes.Next,considering from the specific micro-levels,the researcher elaborated the method of ecological restoration of topography,soil,water body,plant,industrial solid waste in the site.Through theoretical research and case analysis,the researcher proposes a landscape ecological restoration strategy for Three-line Construction industrial sites: a set of scientific evaluation methods for the value of site landscape ecological environment and industrial heritage.The methods should take both of them into consideration.Starting from the landscape ecological design level and based on the ecological restoration technology,the mutual integration of landscape design and ecological restoration will be done to better protect the value of industrial heritage.The ecological environment will be better developed and utilized,providing theoretical support for the construction of urban ecological environment.
