摘　　要：文章对广州中心镇绿地中不同公共与道路绿地斑块的生态效应进行对比分析和研究,探讨了不同的绿地斑块在物种丰富度、三维绿量、空气质量改善、降温增湿等方面的差异及原因,指出目前村镇绿化中主要存在应用种类不足、绿地结构简单、生态效益差、养护水平低下等问题及解决途径,说明叶面积指数在绿地生态结构与生态功能中起着关键指标的作用,以期为新农村建设中绿化生态建设提供技术支撑。This paper presented some main opinions on the ecological construction of the green land in Guangzhou rural town.The ecological effects of different plant communities in Guangzhou rural town greenland were comparative analysed and the cause-effect relations on the species abundance,the tridimensional green biomass,air quality improvement,temperature-decreased and humidity-enhanced effects among different plant communities were discussed.The problems existed in rural town green land such as species-lacking,simplified ecological structure,weak ecological effectiveness,poor management were pointed and the solutions were discussed.Leaf Area Index（LAI） was recommended as a key index to the ecological structure and the ecological function of rural town greenland.;
