Title: Comparison and evaluation of improvement model of forest form for landscape and environmental protection in urban forest park: taking Laoshan National Forest Park as an example.
Abstract: Taking two functions of landscape and environmental protection as a main target,improvement of four types of forest form in Laoshan National Forest Park was carried out.Pure forest community of Pinus massoniana(A1),pure forest community of Celtis sinensis(B1),coniferous mixed forest community of Metasequoia glyptostroboides-Platycladus orientalis(C1) and broadleaved mixed forest community of Quercus acutissima-Celtis sinensis(D1) mainly containing deciduous tree were respectively transformed to community of Pinus massoniana-Rhododendron pulchrum(A2),mixed forest community of Celtis sinensis-Sapium sebiferum-Osmanthus fragrans-Ilex cornuta-Photinia×fraseri 'Red Robin'-Scilla scilloides(B2),coniferous and broadleaved mixed forest community of Metasequoia glyptostroboides-Platycladus orientalis-Liquidambar formosana-Broussonetia papyrifera-Trachycarpus fortunei-Liriope platyphylla(C2)andbroadleavedmixedforestcommunityofQuercusacutissima-Celtissinensis-Cinnamomum camphora-Ligustrum lucidum-Osmanthus fragran-Yucca gloriosa-Pittosporum tobira-Liriope platyphylla-Trachelospermum jasminoides(D2) mainly containing evergreen tree.And taking two aspects of community structure and benefit,selecting ten evaluation indexes including canopy density,species richness,landscape-level structure,crown horizontal projection overlap area,ratio of evergreen to deciduous species,absorption ability to harmful gas,sluggish dust and sterilization ability,seasonal change,landscape beautiful degree and recreation resources and according to weight and valuation of every index,the evaluation system of improvement model of forest form for landscape and environmental protection in urban forest park was established by analytic hierarchy process(AHP).The evaluation result shows that scores of different indexes and comprehensive scores of forest form for different communities after transformation all are higher than those before transformation.Especially,landscape-level structure,seasonal change and landscape beautiful degree of community D2 are the best with the strongest environmental purification function,realizing the organic combination of landscape and environmental protection.It is suggested that improvement of community model for landscape and environmental protection in urban forest park must consider physiological-ecological characteristics of plant itself,and also emphasize beauty of individual plant and community.
