湖南烈士公园植物群落的观赏效果及生态效益比较分析

Comparative analysis of plant communities’ ornamental effects and ecoefficiency of Hunan Martyrs Park

研究选取湖南烈士公园内的4个人工栽培群落,对群落树种组成、群落结构进行了调查。对于4个植物群落一年四季的季相变化及观赏效果,以照片形式记录,比较分析了4个植物群落的整体景观效果。用照度计、温湿度计、CO2测定仪测定群落内外光照强度、温湿度、CO2浓度;分析实验结果,对4个植物群落的生态效益进行比较。以调查及实验结果为依据,综合比较分析了4个植物群落的景观效果、实用功能及生态效益,对城市人工栽培群落的构建进行了探讨。

By selecting 4 plant communities in Hunan Martyrs Park as the studied objects,theirs community species composition and structure of community were investigated.The seasonal variations and ornamental effects of the four plant communities all year round were recorded in the form of photos,and the overall landscape effects of the 4 plant communities were compared and analyzed.The illumination intensity,temperature and humidity and concentration of carbon dioxide inside and outside the communities were determined by using luminometer,thermometer,hygrometer and carbon dioxide analyzer.The observed results were analyzed,and the ecological benefits among the 4 plant communities were compared.Based on the survey and observed data,the four communities’ landscape effects,utilitarian functions and eco-efficiency were comprehensively compared,thus discussing the way to constructing the artificial cultivation plant community in city.
