摘要
植物中叶绿素含量是植物生理生化及生态调查中的一个重要测量参数。它不仅是表达植物生物量的一个指标,也是检测植物健康程度及环境因子的关键指标。阐述了叶绿素性质、作用、检测技术研究进展,分析了植物中叶绿素含量在植物种内、种间时空异质性分布的原因,以及与环境因子的相关性,提出利用植物叶绿素含量进行植物营养诊断和环境因子监测。指出传统叶绿素测定方法不足,建议采用新的测量方法及时测定大范围、大尺度的森林生态系统叶绿素含量,为林木营养状况检测、森林培育等提供良好的参考依据。最后对叶绿素指标在森林生态系统、城市林业中的应用作了展望。
Plant chlorophyll content is an important measurement parameter in physiological,biochemical,biophysical and ecological research.It serves as a key index not only for plant growth and biomass estimation, but also for detecting plant health and its relation to environmental factors. In this article the characteristics and function of plant chlorophyll were described and the advances in the determination and analytic techniques, spatiotemporal heterogeneity, and inter-specific variability of chlorophyll and its relation to environmental factors were reviewed. In view of these chlorophyll characteristics, it can be a good indicator to diagnose plant nutrition level and inspect environmental effects on plant growth. It was suggested that it is time-consuming and high-cost determination in traditional methods,but SPAD-502 Chlorophyll Meter will be a good sun, gate to determine chlorophyll content at forest ecosystem level to provide good reference data for ecological research. The general perspective on the future application of chlorophyll index in forest ecosystem and urban forest study was put forward.
