Urban Park Planning And Design Based On Habitat Diversity Creation

While the city continues to develop and the urban population continues to grow,urban parks often aim to improve the ornamental nature of green space and increase recreational services,neglecting the ecological nature of green space and the ecological recreational experience of visitors,and neglecting the great potential of urban parks of a certain scale as urban biological "habitat sources" and "stepping stones".This makes the city park,the most potential biological habitat in the city,not make a positive contribution to urban biodiversity.As an important part of the ecosystem,biodiversity is an important criterion for judging the ecological quality of cities.Therefore,the planning and design of urban parks with the purpose of habitat diversity creation aims to improve the habitat quality,biodiversity level and ecological value of urban parks based on meeting the recreational needs of visitors and under the guidance of related disciplines,to establish an urban park habitat system with symbiosis of human and natural organisms,to enhance the sustainable development of urban parks,to improve the ecological experience of visitors and to strengthen the nature education of citizens.This paper takes habitat creation in urban environments as an entry point and focuses on the habitat planning and design methods for urban parks with the aim of biodiversity.By clarifying relevant concepts,studying relevant theories and domestic and foreign literature,we summarize the general ideas and common methods of habitat creation from macroscopic to microscopic scales;build connections with biology,ecology,landscape ecology and other disciplines;and provide means of habitat diversity creation in different habitat structures.Through relevant case studies,we also summarize the similarities and differences of habitat creation strategies and planning points and design points.Through the analysis of the value of urban park habitat creation,influencing factors(positive factors and negative factors),spatial pattern,spatial scale and composition elements,the significance and key issues of urban park habitat creation are clarified,and on this basis,the planning and design methods for urban park habitat diversity creation are sorted out-through urban park background Based on the survey of urban park background,we establish the classification system of urban park habitats and the potential animal system of urban parks;combine the research results of relevant experiments and theories at home and abroad to study the habits of animal types,the influencing factors of urban distribution and the requirements of habitats;based on the development of habitat suitability evaluation methods,we construct habitat suitability indicators and design points suitable for urban park planning and design;based on the positioning of meso-habitat structure,the current situation Based on the positioning of meso-habitat structure,the judgment of habitat value,the evaluation of water ecological quality,the analysis of the degree of human interference,and the analysis of the surrounding status quo,the planning structure of micro-habitat is established,and the "core ecological zone","primary buffer zone",and "secondary buffer zone" are delineated."The habitat structure planning principles were proposed,and the target organism construction strategies were established;four habitat construction strategies were proposed: water body and waterfront construction,plant construction,artificial facility construction,and human interference control.Finally,combining with the research results,the application of urban park planning and design based on habitat diversity camping is carried out based on the current situation of the site,existing problems and superior planning,taking Beijing Lotus Pond Park as an example.
