Research On The Functional Complex Development Of Jinan Quancheng Park Based On Functional Performance Evaluation

Influenced by the cross-integration of multi-disciplinary theories,urban parks have been continuously developing with complex functions since their establishment.With the acceleration of social development and urbanization,the pace of urban park renovation and upgrading,which is mainly due to the issuance of a large number of policy documents related to urban park improvement,is gradually accelerating.In order to adapt to the problems of adaptability and diversity caused by the sudden stacking of park functions,and to alleviate the contradiction between limited land resources and increasing demands faced by urban parks,scientific overall planning of urban park functions is carried out,so as to meet the needs of functional transformation.It is very urgent and necessary to ensure that other functions will not be weakened due to the transformation while leading to the increase or enhancement of some functions.Starting from the functional performance evaluation in landscape performance,the thesis constructs a functional quantification model and a functional composite development prediction model on the basis of classifying,summarizing,quantifying and evaluating the functions of urban parks.Provide reference and technical support.On the basis of dividing the functions of urban parks into ecological functions,social functions,and economic functions,according to the relevant functional quantification methods in landscape performance and normative documents,36 functional quantification indicators are used to describe stormwater management,habitat creation,air Purification,temperature regulation,viewing and leisure,recreational activities,scientific research and education,health care services,disaster prevention and hedging,convenient transportation,cost saving,management services,and economic stimulation are 13 landscape functions that belong to ecological,social and economic aspects.A functional quantitative model for evaluating the functional performance of urban parks.By dividing the functional development history into different stages,collect statistics on the data required for the functional quantification model in the nodes of each stage,carry out normalization and normalization on the obtained functional quantification results,and use regression models and regression curves.To predict the degree of functional compounding,a forecasting model for the development of functional compounding was developed,which was used to discover the law of complex development of park functions,and then put forward optimization suggestions for the problems existing in the development of parks.This thesis takes Jinan Quancheng Park as an example,and applies the above-mentioned research methods to evaluate the function performance and function complex of Quancheng Park.During the period from the establishment of the park in 1989 to the end of 2021,it is divided into "specialized parks-park construction","specialized parks-free opening","comprehensive parks-comprehensive reconstruction","comprehensive parks-disaster prevention reconstruction","comprehensive parks-comprehensive reconstruction",The functional changes and composite situations of the 6 nodes and 5 stages of "Park-Sponge Transformation" and "Comprehensive Park-the end of 2021",it is judged that the functional development of Quancheng Park is in the development mode of "sporadic transformation" from stage 1 to stage 2,and in stages 3 to 2 Stage 5 presents the development model of "special transformation",and the relevant indicators of ecological function and economic function show a good consistency in the development trend,while the relevant indicators of ecological function have poor consistency in the development trend.The development trend of the functional compound degree is that it first rises and then basically stays flat,and the future forecast is a downward trend.Finally,on the basis of sorting out the functional development of Quancheng Park,the special promotion of "Children's Activity Space","Service Building","Park Traffic Convenience Service",and "Scientific Research Vitality" are proposed respectively for the function of decreasing intensity.4 functional enhancement strategies,and for the functions with enhanced potential,it is proposed to continuously carry out the special promotion of "sponge city",special promotion of "biodiversity",special promotion of "characteristic cultural activities",and special promotion of "healing landscape".Suggestions for functional composite enhancement,and suggestions on the functional composite enhancement of other urban parks with reference to the development law and enlightenment of Quancheng Park.
