株洲市城市植物景观分析

Analysis of urban plant-landscape in Zhuzhou City

应用景观生态学原理,结合株洲市城市绿地植物景观现状,选取多样性指数、优势度、分离度和破碎度4个指标,从景观的类型多样性、格局多样性和斑块多样性3个方面,对株洲市城市植物景观进行多样性分析。结果表明,随着人类活动的加强,城市植物景观类型多样性降低,景观类型趋于单一;景观斑块多样性增大,嵌块体形状更趋复杂;景观格局复杂化,结构不稳定性提高,自我组织调节、修复能力削弱。最后,对株洲城市绿地景观的改善提出若干建议。

Based on the principle of landscape ecology the current situation of urban vegetation-landscapes （UVL） in Zhuzhou was studied . The diversity of UVL of Zhuzhou City was analyzed in the paper.which including the diversity, dominance, fragmentation and isolation,four indices and the vegetation-landscape type diversity （TD）, pattern diversity （Pn D） and patch diversity （PD） three aspects. The result shows that with the strengthening of human activity,TD decreases and the landscape types tend to be more simple; PD increases and the shapes of patches become more complex; Pn D become more complex, and the stability of the vegetation-landscape structure decreases and the ability of self-regulation weakens. Finally,some suggestions were introduced to improve the.quality of urban vegetation landscapes.
