Research On The Application Of Native Wild Herbs In Lixian County Under The Background Of Rural Landscape Fragmentation In The North China Plain

Wild is relative to the cultivation of native wild herbaceous plant namely,raw soil in local born in spontaneous state and type of plant,its in the sudden changes in the different environment and environment can still maintain a strong vitality,also can meet the demand of windbreak and sand-fixation,soil restoration ecology,vegetation community is vital to maintain stability of the structure.Wild herbaceous plant resources will greatly enrich the species of garden plants,meet people’s spiritual needs,and at the same time can realize the universality of application,but also can provide unlimited sources for new variety cultivation,have broad prospects for development.The process of urbanization in North China Plain has led to the fragmentation of rural landscape and the loss of local features.The investigation and analysis of the current situation of native wild herbaceous plants in Lixian county can directly provide the basis for the remolding of rural landscape in north China plain,indirectly provide fresh plant materials for the practice of urban landscape greening with similar climatic types,and indirectly benefit the protection of wild plant resources.From April to August in 2020,this study took the villages around Lixian County as the basic investigation points,and the species,characteristics and distribution of wild herbaceous plants were the main contents of the investigation.The landscape application value of different native wild herbaceous plants was evaluated based on analytic hierarchy process.The landscape application patterns of major native wild herbaceous plants were also discussed.The results are as follows:(1)In total,there are 73 species,64 genera and 28 families of native herbs in Lixian County,among which Asteraceae has the most species,followed by Amaranthaceae and Poaceae.(2)The native wild herbaceous plants in Lixian County have good diversity in the aspects of family species,ornamental characteristics,ecological adaptability and potential value.(3)By comprehensive evaluation of three first-order factors including ornamental characteristics and 12 second-order factors including plant type,Taraxacum mongolicum and Youngia japonica had the highest application value and could be selected first.Among them,Limonium bicolor,Crepidiastrum sonchifolium and Salvia plebeia have the highest ornamental characteristics,which can be properly expanded in application scale.(4)Suggestions on the application of wild herbaceous plants were put forward from the perspectives of rural landscape reconstruction,the needs of different populations,the protection of plant resources and the future development of rural areas,and the importance of building an integrated germplasm resources garden and a small special garden was emphasized.
