基于三维绿量的城市绿地生态效益评价综述

绿量是定量化研究城市绿地生态效益的重要指标,它更加准确的反映了植物的冠层结构,并且大大增强了城市绿地建设的科学性和可靠性,为合理配置园林植物、改善绿量结构以及城市绿地规划提供重要依据。因此,三维绿量的研究意义重大。通过对近年来绿量及城市生态效益的研究进展做了阐述,并针对中国今后量化生态效益产生的问题及研究趋势进行了讨论。最后指出完善三维绿量的测算方法、构建城市绿地生态效益评价模型是未来量化生态效益的研究重点。

Review on Ecological Benefits Evaluation of Urban Green Space Based on Three-dimensional Green Quantity

Green quantity is an important index in quantitative study of the ecological benefits of urban green space, it reflects the canopy structure of plant more accurately and enhances the scientific nature and reliability of urban green space construction, and can provide reference for reasonable collocation of garden plants, improvement of the green structure and the planning of green space. So, the study of three-dimensional green quantity has certain significances. The authors elaborated the progress of green quantity and urban ecological benefits, and discussed the problem of ecological benefits quantization and research trends in the future. Finally, the authors pointed out that the keys of ecological benefits quantization were improving the calculation method of three-dimensional green quantity and constructing the evaluation model of urban green space ecological benefits.
