| With the advancement of the urbanization process,the urban area has been expanding,the urban population density has been increasing,and the pursuit of the natural landscape has become more and more intense.At the same time,the planning and construction of the mountain park in Jinan is in full swing.Jinan is a typical limestone mountain distribution area,and the mountain environment is often characterized by poor soil,thin soil,many plants are difficult to grow well.Therefore,in the early planning and construction of mountain parks,the selection of suitable plants has become the first to solve the problem.Through the extensive reading and analysis of the literature summary,based on the direction of many related research scholars,as well as the research area of on-the-spot investigation and exploration for many times,finally formed based on jinan city limestone mountain mountain park site type selecting woody plants selection method and results.This article from the following aspects:First,it is based on the analysis of basic data summary,clear research methods,purposeful for progressive research and data records.The principles and basis of the selection of samples in the study area were established and the samples were determined under the premise of this,and the samples were analyzed.Second,according to the actual situation and experience,combined with the existing theoretical basis,developed a clear plant selection principles and standards,and strive to guide this more targeted and scientific and rational selection of suitable plants.The principle of plant selection mainly includes: native tree species as the dominant,alien species to supplement;strong adaptability and resistance;suitable for extensive management;selection diversity;has a certain ornamental value of 5 items.Thirdly,the systematic selection of plant selection method was established.Firstly,44 species of commonly used trees,30 species of shrubs and 8 species of woody vines were selected from the frequency of plants in the sample area.A total of 81 kinds of Jinan main urban areas Limestone mountain park commonly used woody plants.Fourthly,AHP was used to establish a comprehensive selection system of woody plants suitable for growth in limestone mountain park in Jinan main city.The preliminary research data were used as data to support the preliminary screening of the commonly used plants.Select the system for the second choice.Using SPSS for clustering analysis,13 species of arbored trees with 13 grades of grade ? and 19 species of grade ? were selected from the limestone mountain park in Jinan main urban area.There were 12 kinds of shrubs with grade?,There are 7 kinds of shrubs of grade ?,5 species of woody vines with grade ?,and the plants which are evaluated as ? and ? are popularized and applied.Fifthly,we determined the main site factors,divided the site type,and randomly selected the corresponding sample according to the site type.The second comprehensive evaluation of the selected plants was taken as the research object.Through the common screening of frequency and growth status evaluation,The different types of site types were matched with the selected plants,and the species of suitable plants under the dominant site type of limestone mountain park in Jinan city was established.In this paper,a large number of research work,combined with quantitative and qualitative analysis,the system of science to develop a plant selection method,and through this method to select the main city of Jinan City limestone mountain suitable woody plant species.The choice of mountain plants provides a strong theoretical support and practical reference. |
