深圳东湖公园植物多样性研究

摘要

Donghu Park is one of the most famous comprehensive parks in Shenzhen.Through field survey and plot method, a total of 536 species and varieties of vascular plants, belonging to 124 families and 363 genera were recorded in the Park. There are 399 of which (74.4%of the total species) were native and 137 (25.6%) were exotic.Comparison of floristic diversity of three major plant communities, plantations on hill slope, plant communities along road and special gardens showed that the green spaces in theme gardens had high species richness, diversity of trees and herbs, but the species richness of shrubs and evenness of herbs were low. Compared with road and theme gardens, the plantations on hills usually had higher species diversity, evenness of shrubs and fewer herbal species. Based on the above study, the plant landscape scenic features of Donghu Park were summarized. And provide some suggestions to improve the hilly plantations, old tree protection and park safety.%东湖公园为深圳市著名的综合性市政公园之一。通过实地踏查和样方调查，在园区共记录了维管植物536种（含亚种和变种），分别隶属于124科363属。其中，乡土植物399种，外来种137种。比较研究了东湖公园山地人工林、道路绿地区和专类园区绿地植物群落的物种多样性。结果表明，专类园所应用的种类相对较丰富，乔木层和草本层的物种丰富度和多样性均较高，但其灌木层的植物丰富度和草本层的均匀度相对较低。与园路区和专类园区相比，山林区植物群落的灌木多样性和均匀度较高，但草本植物种类较少。基于研究结果，总结分析了东湖公园的植物景观特色，探讨了园区山地人工林的改造、古树保护及景观安全维护问题。
