Landscape Evaluation And Application Of Typical Plant Community In Laobiangou Scenic Are

With the development of economy,suburban scenic spots have become more and more tourists' choices due to the original ecological natural environment and the more convenient transportation in the current society.However,with the arrival of tourists,some unreasonable development and management of scenic spots are being destroyed The plant landscape in the scenic area destroys the local ecological resources.Plant community is an important carrier of plant landscape construction in scenic spots,and its advantages and disadvantages determine the ecological functions of scenic spots and the beautification functions of scenic spots.With the enhancement of people's aesthetic and ecological awareness,people have higher standards for the ecological function,landscape function and recreational function of the plant community landscape.Therefore,the investigation and evaluation of the plant community landscape in scenic spots is particularly important.This thesis takes the plant community of Laobiangou scenic area as the research object,and records the plant community landscape data of 36 sample plots in Laobiangou scenic area through field investigation.According to the survey data,the basic characteristics,diversity index and viewing The characteristic index is analyzed.The AHP method and the BIB-LCJ method were used to evaluate the landscape quality and beauty of 36 sample plots,and the current problems in Laobiangou Scenic Area were found,and optimization suggestions were put forward.The research results are as follows:(1)There are 2091 plants in the surveyed scenic spots,including 45 species of trees,accounting for 65.9% of the total;10 species of shrubs,accounting for 9.04% of the total;532herbs,accounting for 25.4% of the total;3 species of vines,accounting for 0.48 of the total %.There are 4 kinds of evergreen plants,20 kinds of deciduous plants,the ratio is close to 1:5,3kinds of evergreen plants are evergreen trees,1 kind of evergreen shrubs,deciduous plants have 11 kinds of deciduous trees,9 kinds of deciduous shrubs,The dominant family is Aceraceae.According to the survey and statistics of garden plants,in terms of ornamental characteristics,the plant landscape of Laobiangou Scenic Area has obvious seasonal characteristics.The plant landscape uses deciduous trees as the background color,and the deciduous trees are mainly spring and autumn,supplemented by winter and summer,forming a vivid and colorful vegetation landscape in four seasons.(2)The AHP method and the BIB-LCJ method were used to evaluate the plant community landscape of the Laobiangou Scenic Area.The AHP method evaluation results showed that the overall value of the plant landscape of the Laobiangou Scenic Area was in the upper middle and had a certain economic value.Development value.The evaluation results of the BIB-LCJ method show that the three evaluation objects have roughly the same evaluation values for the sample plots,indicating that people's pursuit of beauty is the same.In addition,the ranking of the comprehensive evaluation scores of the double evaluation method is not completely consistent,and there are certain ranking differences.(3)According to the results of the investigation and evaluation,the current problems in the Laobiangou scenic spot have been discovered and optimization suggestions have been made.By discovering the uneven distribution of landscape characteristics in the Laobiangou Scenic Area,it is proposed to reasonably allocate the seasonal characteristics of the scenic landscape,and to increase the planting of dry and fruit-viewing plants in winter;it is found that the planting ratio of evergreen and deciduous trees is unreasonable,and appropriate increase is proposed.Plant evergreen trees to coordinate the proportion of evergreen and deciduous trees;find that the plant maintenance and management in scenic spots is improper,and propose to use scientific maintenance techniques for later management;address the problems of low staying in the scenic area and certain hidden safety hazards,It is recommended to add viewing platforms and landscape walls to improve the stay ability and safety of the plant landscape.
