The Status Analysis Of Plant Landscape For The Guangzhou Tianlu Lake Counter Park

Country park, an essential element of suburbs, has an important ecological functionand aesthetic value, has a great effect for urban biodiversity conservation, the constructionof harmonious living environment and controlling urban expansion. In recent years, with thedevelopment of country parks construction, it is of important theoretical and practicalsignificance to analyse and assess the established country parks comprehensively. Speciescomposition and phytocoenosium structure were investigated in Tian Luhu Country Park ofGuangzhou. Different typical landscape types are selected for the analysis and on the basis,the optimal measures are also discussed. Plants landscape and recreation function wereevaluated in questionnaires,The results were as follow:1. There were338species of vascular plant species in Tian Luhu Country Park ofGuangzhou, belonging to253genera of116families, in which309kinds of Angiosperms,gymnosperms and ferns were seldom used. On the basis of life form, the species ofeven-green arbor was most, shrubs and herbs were less, and vines were seldom. Thepercentage of indigenous plants was high in Tian Luhu Country Park, the vegetation issecondary evergreen broad-leaved forests and theropencedrymion of the subtropics, it has acertain transitional nature with tropical and subtropical flora.2. In the tree layer, important values of Schima argentea, Triadica cochinchinensis andCastanopsis fissa is high. Castanopsis fissa, Psychotria asiatica and Ficus hirta take thelead in the shrub layer. Blechnum orientale, Dianella ensata and Scleria ciliaris is importantin herb layer. This paper analysed the species richness, species diversity index andcommunity evenness in in Tian Luhu Country Park of Guangzhou, the average speciesrichness is9.9, the average Gleason index is2.77, average Margalef is2.14, averageSimposon index is0.79, average Shannon-Wiener index is1.48, community evenness（Pielou index） is0.68. So it indicates that plant species are rich, species diversity is high.3. Three Near-natural plant communities in Tian Luhu Country Park are evaluated,waterside type near-natural plant communities, level ground type near-natural plantcommunities, mountain type near-natural plant communities. The optimization of theprinciples and strategies of these landscape are proposed to explore an appropriate mode. 4. Through the analysis of80valid questionnaires, draw the satisfaction and theopinions of the improvement suggestions about transportation, plant landscape andinfrastructure from citizens.
