黑龙江自然植物群落调查与寒地城市绿化模拟策略

A Survey of Natural Plant Community and Simulation Strategy of Urban Greening in Heilongjiang Province

为了促进近自然植物群落建设,实现寒地城市绿地植物景观建设的可持续发展,采用样区—样地—样方调查方法,以黑龙江省帽儿山、虎林、延寿、沾河、孙吴、呼玛、塔河、漠河等样区自然植物群落为研究对象,对群落的乔灌木种类组成、乔木密度、郁闭度及叶面积指数等指标进行了调查。结果表明,不同样区自然植物群落的种群组成、景观效果、冠层参数差异较大。在寒地城市绿化中,应以自然植物群落为参考,合理设置乔灌木种类、规格与栽植密度,促进群落稳定增长。

This paper adopts sample region-sample plot-quadrat investigation method so as to conduct a systematic survey on important indexes of plant communities, such as species composition of arbors and shrubs, density of arbors, canopy density, the leaf area index of natural plant communities in Mao＇ ershan, Hulin, Yanshou, Zhanhe, Sunwu, Huma, Tahe, Mohe, etc., in order to promote the near natural plant community construction and realize the sustainable development of plant landscape construction of green space in winter city. The research suggested large differences in the level of growth and development, the hierarchy and landscape patterns of different natural plant communities. Results show that the population structure, landscape effect and canopy parameters of natural plant communities in different areas are very different. As for winter city greening, it is suggested to refer to plant community, correctly arrange the varieties, specifications and planting density of arbors and shrubs in groups, and promote the community-stable growth.
