Evaluation And Analysis On The Current Situation Of Cultivation And Maintenance Of Garden Plants In Urban River Protective Green Space In Jingzhou City

As a key part of the urban green space system,urban protection green space plays a pivotal role in urban environmental protection and improvement.In cities with dense water networks,urban river protection green space is an important part of urban protection green space,and the function of green space is fully utilized.Not only rely on the overall planning and layout in the early stage,but also need scientific and reasonable standardized cultivation and maintenance work.At present,there is an unreasonable situation in the cultivation and maintenance of garden plants in urban river protection green space in Jingzhou City,and there is a lack of scientific,reasonable and detailed evaluation criteria.In this paper,through the field investigation of the urban river protection green space and garden plant information in Jingzhou City,the current situation of garden plant cultivation and maintenance in green space is evaluated by the analytic hierarchy process,and the problems existing in the current situation of garden plant cultivation and maintenance are summarized and suggestions are put forward.Summarize the content and technical points of garden plant cultivation and maintenance,and analyze the applicability of garden plant cultivation and maintenance in urban river protection green space in Jingzhou City.The main findings are as follows:1.Through the investigation and summary of information on river protection green space in Jingzhou City,Honghu City and Jiangling County.The results showed that a total of 76 species of garden plants belonged to 37 families and 56 genera.The species richness of garden plant resources in river protection green space in Jingzhou City are Jiangling County,Jingzhou City and Honghu City in descending order.The dominant plants,dominant species and overall dominant species of garden plants in river protection green space in Jingzhou City were calculated.According to the functional status of the survey sites,the urban river protection green space in Jingzhou is divided into: garden type,artificial landscape type,and near-natural type urban river protection green space.2.The analytic hierarchy process is used to establish three criteria indicators including plant cultivation,plant maintenance and green space management,and 12 specific evaluation indicators.According to the configuration characteristics of different types of green space plants,the garden plant cultivation and maintenance evaluation of Jingzhou river protection green space is divided into two part.Among them,the second-level evaluation index of garden plant cultivation and maintenance in garden-type and artificial landscape-type urban river protection green space accounts for the largest weight of plant maintenance,and the total weight of pruning and shaping and disease and pest damage in the third-level evaluation index exceeds10%;The green space management has the largest weight in the second-level evaluation index of garden plant cultivation and maintenance in river protection green space,and the total weight of plant selection and safety protection in the third-level evaluation index exceeds 10%.3.According to the evaluation index system and scoring standard,the sample points of the two parts were scored.The results showed that,except for the indicators with no reference value,the Cronbach coefficients of the remaining indicators in the two parts were 0.7 and 0.884,respectively,which had good reliability.The cumulative variance contribution rates of the analysis were 78% and 63%,respectively,with good validity.The final score of each sample point after the weighting operation,the results show that 2 of the sample points with a final score of more than 5 points account for 3% of the total sample points,and 5 of the sample points with a final score of less than 3 points account for 8 of the total sample points.%,and the final scores of the remaining sample points are between 4 and 5points,indicating that the cultivation and maintenance of garden plants in river protection green spaces in Jingzhou City are generally poor,and the problems are mainly distributed in adequate planting,growth potential,plant selection,pests,diseases,and pests.There is great room for improvement and improvement in the indicators of debris and garbage.4.On the basis of on-the-spot investigation and current situation evaluation,this paper summarizes the problems of garden plant cultivation and maintenance in different types of urban river protection green spaces,such as insufficient planting of garden plants,unreasonable selection of garden plants,low level of garden plant cultivation technology,and untimely maintenance of garden plants in the later stage.,inadequate management of green space,etc.,and put forward improvement strategies such as fully planting garden plants,rationally selecting plants,improving cultivation technical regulations,improving maintenance measures,strengthening green space management,and eliminating potential safety hazards.5.By summarizing the main content and technical measures of garden plant cultivation and maintenance,combined with the reference of relevant standards and the analysis of the characteristics of the content,aiming at the current situation of garden plant cultivation and maintenance in Jingzhou city’s urban river protection green space,explore the garden plants in Jingzhou city’s urban river protection green space The deficiencies of the applicability of cultivation and maintenance technical measures are proposed,and the research ideas of applicability standards for classification and integration,reference and adjustment are proposed.
