Investigation And Evaluation Of Woody Plant Resources In Mount Culai

Plant resource is one of the basic elements of today’s garden architecture.Plant resource can not only create a beautiful environment,but also improve the environment on which humans depend.It plays a fundamenta lrole in the construction of ecological civilization today.China’s abundant plant resources have been widely used in the world,which plays a very important role in the progress and development of the world’s gardens.Therefore,China is known as the mother of the world garden.Wild ornamental plant resources are an important part of plant resources and a source of future landscape architecture and ornamental plant breeding.Therefore,the protection,development and utilization of China’s existing wild plant resources have become the top priority of landscape construction.After investigation,the development and utilization of native wild ornamental plants in Shandong Province is mainly focused on resource survey and introduction,while the research on resource evaluation is relatively rare.The wild plant resources of Mountain Cuslai are very rich.It is one of the most abundant plant resources in Shandong Province.The composition of flora is also very complicated,but the research on the investigation and evaluation of wild plants in Mountain Cuslai is rarely reported.This paper takes Mountain Cuslai as the survey site and focuses on the investigation of the current woody plants.The survey results show that there are 333 species of woody plants in Mountain Cuslai,belonging to 60 families and 135 genera.According to the growth habits of tree species,there are 99 species of trees,54 species of shrubs,and 9 species of vines.The main growing communities of Mountain Cuslai woody plants are coniferous forest,broad-leaved forest and shrub.The main group of coniferous forest is Pinus densiflora,the broad-leaved forest is mainly deciduous broad-leaved forest,and the species are Robinia pseudoacacia,Populus,Pterocarya stenoptera,Castanea mollissima,Quercus acutissima and other deciduous broad-leaved trees.The main shrub layer is composed of Vitex negundo var.heterophylla,Lespedeza bicolor,Actinidia arguta,Euonymus alatus and Phyllostachys glauca.In the survey of plants in Mountain Cuslai,there are 7 kinds of rare and endangered plant species at the national level,namely,Tilia amurensis,Kalopanax septemlobus,Juglans mandshurica,Quercus mongolica,Schisandra chinensis,Actinidia arguta,Actinidia polygama.There are 14 kinds of rare and endangered tree species in Shandong Province,namely,Schisandra chinensis,Lindera obtusiloba,Actinidia polygama,Juglans mandshurica,Kalopanax septemlobus,Eleutherococcus sessiliflorus,Ulmus parvifolia,Quercus mongolica,Rhododendron mucronulatum,Actinidia arguta,Hovenia dulcis,Acer grosseri var.hersii,Chionanthus retusus,Tilia amurensis.Two species of wild tree species were newly discovered,namely,Lindera obtusiloba and Rhamnus bungeana.From the woody plants surveyed in Mount Culai,78 species of wild woody ornamental plants were selected,and the landscape evaluation was carried out.13 indicators were identified from three aspects : ornamental value,ecological value,and application value.Then,the evaluation system of Mount Culai is established by AHP and evaluated comprehensively.The results showed that 28 species of wild resources such as Pyrus betulifolia,Diospyros kaki,Amygdalus,Juglans cathayensis,Rhus chinensis,Armeniaca vulgaris,Corylus heterophylla,Quercus wutaishanica,Ziziphus jujuba,Crataegus pinnatifida,Chionanthus retusus,Viburnum opulus,Pyrus bretschneideri,Kalopanax septemlobus,Salix pseudopermollis and Sabina chinensis were Class I plant resources,and the development and utilization value is very high.The three kinds of plants,Clerodendrum trichotomum,Actinidia polygama and Rhododendron micranthum,are Grade II plant resources,and the development and utilization value is not significant,and can be moderately developed and utilized;Populus tomentosa,Callicarpa dichotoma,Carpinus turczaninowii,Celtis bungeana,Dalbergia hupeana,Diospyros lotus,Populus simonii,Salix matsudana,Albizia kalkora,Broussonetia papyrifera,Celtis koraiensis,Hovenia dulcis,Fraxinus chinensis,Euonymus oxyphyllus,Vitis heyneana and other 47 plants are Class III plant resources.The value of development and utilization is low.The survey data of wild woody ornamental plants in Mount Culai provide reliable theoretical support for the future investigation of wild plants in Mount Culai.
