Qualitative and Quantitative Evaluation of Forest Plant Community Landscape Unit in University Campus
By taking the college campus forest in Liuzhou City as the research subjects,33 plant landscape units were selected as the evalua-tion plots from 5 functional areas of campus green space,and evaluated by using Anglytic Hierarchy Process(AHP),and a landscape plant assessment model was established.The results were as follows:in the criterion level weights,the ecological function(F1 =0.508 7)was a-mong the highest score,the utility function(F2=0.247 0)was the second,followed by the cultural functions score(F4=0.132 7),the last one was the landscape function score(F3=0.1116);in the index level weights,plant species diversity was the highest score(G1=0.274 5),fol-lowed by the diversity of plant community vertical structure(G2 =0.151 1),the can stay(G6 =0.113 3),the diversity of plant life structure(G3=0.083 1),and the anti-jamming ability(G5=0.113 3).The comprehensive scores of 5 functional areas,the science district(7.158)was among the highest score,the recreation area(6.912)was the second,followed by the sports area score(6.159),the last one was the dormito-ry area score(5.763),which showed the landscape quality needs to be strengthened.Based on the evaluation results,three good plant ar-rangement modes were recommended.The AHP method combines quantitative evaluation with qualitative evaluation which has a certain guiding significance for college campus forest plant landscape construction,and provides a method for college campus forest plant landscape evalua-tion.
