Research On Digital Construction Of Urban Habitat Network From The Perspective Of Indicating Biological Habitat Protection

In recent years,China’s urbanization process has been accelerating.While great achievements have been made in social and economic development,the ecological environment is facing many challenges.Ecological problems such as environmental pollution,destruction of animal and plant habitats,and sharp decline in biodiversity have threatened the country’s ecological security pattern and sustainable development strategy.Based on this,the urgency of ecological civilization construction has been unprecedentedly increased,and the importance of habitat network construction with the goal of biological habitat protection has become increasingly significant.At present,there have been many studies and practices on ecological space and habitat networks,but how to use multi-scientific theories and digital technologies to construct habitat networks with the protection of biological habitats in the site as the original design is still in the exploratory stage,so there is an urgent need for A set of digital construction methods for urban habitat networks from the perspective of habitat protection of focal species.This paper takes the focus species of typical habitats as the starting point,takes habitat protection as the development direction,takes multidisciplinary related theories as the research basis,and uses big data and composite models as technical means,and proposes a set of habitat protection based on focus species.The method of digital construction of urban habitat network from the perspective of the city,and take Shenyang as an example to practice.The main contents and achievements of the paper are as follows:(1)Research and discuss related concepts,theories and construction methods of habitat networks,and sort out and summarize research papers and practical projects at home and abroad.The first is to differentiate and analyze the concept of habitat network and related theories,then to sort out the research process of habitat network,and finally to summarize the research progress at home and abroad.Through in-depth research on basic theories,we will further clarify the meaning,content,technical methods,etc.of urban habitat network construction in my country,and finally summarize and summarize on the basis of literature study,and propose a habitat network based on the perspective of habitat protection of key species.Construct methods,and make relevant conceptual definitions and method descriptions.(2)A set of technical methods for the construction of a full-process,digital habitat network has been formed.Through the research and screening of focal species in typical habitats,the simulation and generation of potential species habitat networks,the synthesis and optimization of multi-focal species complex habitat networks,and the simulation and feedback of future habitat networks under different scenarios,the final conclusion is that habitat network construction is proposed.overall strategy.Thus,a set of methods for digital construction of urban habitat network from the perspective of habitat protection of focal species,which integrates research,analysis,construction,simulation,and feedback,is formed.(3)Apply and practice the habitat network construction method constructed in this study to verify its feasibility and reliability.Taking the central urban area of ??Shenyang as the practice site,and focusing on species of Great Spotted Woodpecker,Mallard,and Squirrel,the potential habitat network of the three types of organisms was constructed.The composite habitat network based on multi-focal species is compared with the 10-year simulation prediction and results under the natural development scenario and the artificial intervention scenario,so as to verify the benefits generated by this study,and obtain the comparison results.On this basis,feedback design,and finally put forward the overall strategy of Shenyang habitat network construction.The full text is 123,571 words,with a total of 87 pictures and a total of 68 tables(including the attached table).Pictures and tables are drawn by the author unless otherwise specified.
