气候变化下城市植物物候变化与规划策略
|
Abstract:
城市绿地系统具有生态防护、美化环境等功能，对于维持城市生态稳定性十分重要。近年来，由于自然演进和人类活动导致的全球气候变化，对城市植被的物候期产生了巨大影响。本文聚焦于探讨气候变化背景下城市植物物候期的变化以及提出相应的城市植被规划策略。首先阐明了结合传统地面观测与现代遥感技术的综合监测体系，该体系能够高精度、全覆盖地捕捉城市植物生长周期的动态变化，为科学研究提供更为精确的数据基础。其次，深入分析了温度上升和降水量变化两大主要影响因子对植物物候期的影响机制，揭示出早春提前开花、夏秋季节生长周期缩短等显著现象。基于上述分析，进而提出了适应气候变化的城市植被规划策略。
The urban green space system, with its functions of ecological protection and landscaping, is important for maintaining the ecological stability of cities. In recent years, global climate change due to natural evolution and human activities has had a great impact on the phenology of urban vegetation. This paper focuses on the changes of urban plant phenology in the context of climate change and proposes corresponding strategies for urban vegetation planning. Firstly, a comprehensive monitoring system combining traditional ground observation and modern remote sensing technology is elucidated, which can capture the dynamic changes of urban plant growth cycle with high precision and full coverage, and provide a more accurate data base for scientific research. Secondly, the mechanism of the two main influencing factors, namely temperature rise and precipitation change, on the climatic period of plants was analyzed in depth, revealing the remarkable phenomena of early flowering in early spring and shortening of the growth cycle in summer and autumn seasons. Based on the above analysis, the urban vegetation planning strategy for climate change adaptation is proposed.
