| South dongting lake has a special geographical and natural environment,in which there are many wild plants,and has a relatively rich species category.In the paper on the analysis of the south dongting lake wild ornamental plants,from the resources of wild ornamental plants category,the specific value,landscape pattern and the development of the corresponding analysis and summarized the problems such as can be used for the landscape resources,sustainable utilization were discussed from the perspective of resource protection,resources conservation and sustainable development and utilization of lay a good foundation.The final results are as follows:Based on the comprehensive investigation on the plant resources of South Dongting Lake,168 species of ornamental plants were selected according to their ornamental value,ecological habits and rare and endangered species.There were 155 species of herbaceous plants,and the other species of woody plants,which were the most important species of ornamental plants in.According to the comprehensive evaluation and analysis of wild ornamental plants in South Dongting Lake,we can see that the higher the comprehensive score,the greater the prospect of the development and utilization of this species.South Dongting Lake has a good ornamental characteristics and good prospect of development and utilization of the herb heracleam moellendorffii,wild carrot,saxifrage,purslane,white clover,Nymphoides,lobular,Herba Violae,Polygonum cuspidatum,Lysimachia water Jiangsu,Scirpus yagara,gold earrings,semi dealbatus,Jiegu capsule slender and sparse grass head,Oriental cattail,Typha christinae reed,reed Pennisetum,milk vetch,Polygonum criopolitanum,Scutellaria barbata,Vicia sativa and motherwort;woody plant species: soapnut,Sapium,Bischofia polycarpa,Salix,Populus deltoides,Italy Yang,Baidu,rose,wild rose,mulberry and so on.Some of the different species scores are not the same,which shows that the species diversity,some species more suitable for development and utilization,and some species due to flowering,ornamental,ecological characteristics as a result of factors comprehensive evaluation score is not high.Most of these wild ornamental plants have the characteristics of wide distribution,strong ornamental value,and strong adaptability.And paper before about the evaluation system of wild ornamental plants as the core,further based on the actual status of the south dongting lake,build form a complete set of system evaluation architecture,at the same time for secondary filter operation and get some ornamental herb as well as the number of form a complete set of quantitative evaluation. |
