Evaluation Of Green Space In Harbin City Park Based On Ecosystem Disservice

With the acceleration of urbanization,biodiversity,ecosystem services and human well-being are all deeply affected by urbanization speed and space-time pattern.Facing the problems caused by urbanization,higher requirements are put forward for the urban ecological environment.In addition to ecosystem services,ecosystem disservices(EDS)should also be included in the scope of assessment when evaluating the benefits of ecosystem for human beings.Urban park green space is an important type of land used to form urban ecosystem.Its ecological value and social value are increasing day by day.Urban park is a special small-scale ecosystem in urban ecosystem,which plays an important role in the formation of urban ecosystem,and has unique ecosystem services and disservices.There are many researches on the service function of urban park green space ecosystem,but few on the disservice of urban park green space ecosystem.This paper takes the urban park green space of Harbin as the research object,takes the relevant framework of the ecosystem disservice(EDS)as the early foundation,and under the guidance of the early foundation theory,studies the causes,types of EDS,evaluation indicators of EDS,the impact of EDS,and so on;the definition and influencing factors of the disservice of urban park green space are included.Through on-the-spot investigation,this paper summarizes and analyzes the ecosystem disservices existing in the park green space,explores the characteristics of the urban park green space ecosystem disservices,and makes in-depth analysis from the perspective of ecology,economy,health and social culture;collects the index level factors related to the ecosystem disservices of the urban park green space,and establishes the urban park based on the ecosystem disservices.Taking Zhaolin Park as an example,the paper makes a comprehensive evaluation of the ecosystem disservice of Zhaolin Park,and finally puts forward corresponding strategies and suggestions for the evaluation indicators.The first chapter introduces the background of the times,the analysis and proposal of the problems,the purpose and significance of the research activities,the main research progress at home and abroad of the negative service of ecosystem,the main research content and technical route of this paper;the second chapter introduces the related concepts and theoretical basis,analyzes the ecosystem disservice influencing factors of the park green space;the third chapter investigates the urban park green space in Harbin;In Chapter 4,the ecosystem disservice evaluation system of urban park green space is established;in Chapter 5,the ecosystem disservice of Zhao Lin Park is evaluated and the corresponding strategies are put forward.Chapter 6 is the conclusion and discussion.
