Study On The Selection And Utilization Of Grey Magpie To Different Habitats In Changchun City

The rapid development of urbanization has affected the original ecosystem,resulting in the decline of biodiversity.Urban wild grey magpie is an important part of urban ecological environment.To study the selection and utilization of different urban habitats and the distribution pattern of grey Magpie in different urban habitats can better protect and enhance the species diversity of grey Magpie in the process of urbanization.In this paper,we investigated the selection and utilization of different habitats of grey Magpie in Changchun City,urban and suburban areas,and carried out relevant research,analyzed the relationship between the distribution of grey magpie and its habitat,looked for its influencing factors,and finally discussed the impact of urbanization on the distribution of grey magpie.The results are helpful to reduce the impact on the grey Magpie in the process of greening and landscape construction in Changchun in the future,and provide a scientific basis for the attraction and protection of grey Magpie in the green space planning process,so as to better ensure the ecological balance and promote the harmonious development of nature while improving the landscape benefits.During the period from October 2020 to January 2021,the author selected 200 sampling points randomly from the urban map of Changchun City within the Fourth Ring Road of Changchun City and carried out a survey of grey magpie,covering the whole winter.Among them,each sample was observed for three times,and the sample method was used for observation and study.According to the location of each sample site,it can be divided into five different large-scale habitats: urban public green space habitat,urban residential green space habitat,street habitat,suburban residential habitat,cultivated land habitat and wasteland habitat.Among them,It is further subdivided into seven small-scale habitats: broad-leaved forest habitat,coniferous forest habitat,broad-leaved coniferous mixed forest habitat,shrub habitat,broad-leaved forest architectural habitat,broad-leaved coniferous mixed forest architectural habitat and architectural habitat.At the same time,with the help of 91 satellite map assistant software and SPSS 23.0 statistical analysis software,the sample points were located and the later data were analyzed and processed.The results are as followsSeven types of habitat factors were investigated and recorded,which were Shannon Wiener's index of arbor and shrub in different small habitats,Pielou's index of arbor and shrub in different small habitats,species and area of arbor and shrub,habitat type,human disturbance,building type and floor area,The grey magpie stayed in different layers of trees.Among them,the paired comparison of the number of grey magpie with the species diversity index and evenness index of trees and shrubs in different small habitats was not significant.The number of grey magpie was as follows: arbor habitat > shrub habitat > Architectural habitat,arbor and shrub species more than arbor and shrub species less.The results showed that there were significant differences in the number of grey magpie compared with different tree and shrub species and coverage rate.The number of grey magpie was as follows: high-grade tree and shrub species > medium-grade tree and shrub species > low-grade tree and shrub species.The coverage rate of tree and shrub was 40%-50% > 30%-40% > 20%-30% > tree and shrub The coverage of shrubs was 10%-20% > that of trees and shrubs was 0%-10%.The number of grey Magpie in coniferous forest > mixed forest > broad-leaved forest > mixed forest architecture > shrub > broad-leaved forest architecture > Architecture.The results of paired comparison between the number of grey magpie and different human disturbance showed significant difference,and the number of grey magpie showed as follows: small disturbance > medium disturbance >large disturbance.The results showed that the number of grey magpie was significantly different with the types of buildings and the area of buildings.The number of grey magpie was as follows: small buildings > roads > medium-sized buildings > large buildings,the area of buildings was 0-10% > the area of buildings was 10%-20% > the area of buildings was 20%-30% > the area of buildings was30%-40% > the area of buildings was 40%-50%.The results showed that there were significant differences between the number of grey magpie and the staying position in different layers of trees.The overall number of grey magpie was as follows:all the trees stayed on the ground > all the trees stayed on the ground > all the trees stayed on the ground.Finally,by using the generalized linear mixed model,it is found that the number of grey magpie in the sample is the result of multiple factors.
