Evaluation Of Plant Community In Dalinghe Scenic Spot Of Chaoyang City

The plant community in the Dalinghe Scenic Area is an important carrier of the ecological environment and plant landscape of the waterfront area of Chaoyang City,and also an important display window for the cultural landscape of Chaoyang City,studying the plant communities in Dalinghe Scenic Area of Chaoyang City is of great significance to the ecological environment transformation and plant landscape construction of Chaoyang City.In addition,the Dalinghe Scenic Area in Chaoyang City is a typical waterfront scenic spot.The research results of its plant community have certain reference and guidance for the study of plant communities in other waterfront scenic spots.This study was conducted under the guidance of landscape ecology,restoration ecology and mathematical statistics,and investigated and systematically analyzed the plant species,hierarchical structure and species diversity of plant communities in the Dalinghe Scenic Area of Chaoyang City.The plant community was comprehensively evaluated from the aspects of ecological structure characteristics and landscape quality,and the following results were obtained:(1)Using the plot survey method to investigate the plant species of the plant community in the Dalinghe Scenic Area of Chaoyang City,and found that the plant community consists of 117 species,including 33 species of trees,18 species of shrubs,61 species of herbaceous plants and 5species of vines.(2)Using the vegetation ecology method to classify the plant community,the plant communities in the Dalinghe Scenic Area of Chaoyang City are divided into three vegetation types,seven groups and 81 groups.The arbor layer plant community can be divided into 33 groups;the shrub layer plant community can be divided into 18 groups;the herb layer plant community can be divided into 7 groups and 30 groups.(3)Using the data analysis method to process the survey data and analyze the structure of the plant community,it is found that the plant communities in the Dalinghe Scenic Area of Chaoyang City have a structure of Joe-irrigation-grass(53%)and a structure of Joe-grass(29%),irrigation-grass structure(9%),single-layer grass structure(5%)and Joe-irrigation structure(4%)five vertical structures;and two horizontal structures of pure forest and mixed forest.(4)Using the data analysis method to process the survey data and analyze the species diversity of the plant community,the Shammon-Wiener diversity index of the plant community in the Dalinghe Scenic Area of Chaoyang City is 3.8217,and the Patrick richness index is 11.7595.The ecological advantage Simpson index is 0.9442,and the Pielou evenness index is 0.8195.The Shammon-Wiener diversity index and the Patrick richness index are ranked by numerical order:whole plant community>herbaceous plant community>arbor layer plant community>shrub layer plant community;ecological dominance Simpson index is sorted by numerical order: shrub layer plant Community grass>arbor layer plant community>whole plant community>herbaceous plant community;Pielou evenness index is sorted by numerical order: herbaceous plant community>arbor layer plant community>whole plant community>shrub layer plant community.(5)Using the comprehensive scoring method,expert scoring method and analytic hierarchy process to construct a plant community evaluation system with landscape and ecology coordination,comprehensively evaluate the plant community in Dalinghe Scenic Area of Chaoyang City,and draw the coordination of landscape and ecology.Good degree.From the above research results,it can be found that the development of plant communities in the Dalinghe Scenic Area of Chaoyang City is mainly affected by factors such as self-propagation,natural environment and human activities;the plant configuration has a low utilization rate of herbaceous plant communities,and the plant landscape hue is monotonous.The plant landscape is inconsistent with the surrounding environment and the plant community lacks maintenance management issues.It is suggested to improve and renovate the plant communities in the Dalinghe Scenic Area of Chaoyang City by establishing herbaceous plant landscapes,rationally arranging colorful leaf plants,increasing the size of plant landscape units and strengthening the conservation management of plant communities,and improving their ecological benefits and landscapes.benefit.
