摘　要：

本文介绍了光谱分析技术在植物生理生态研究中的应用。通过分析植物叶片和冠层的反射光谱特征, 可以快速、无 损伤地研究不同环境条件下植物的各种色素含量、叶黄素循环组分、营养状况、水分状况、光能利用效率、植被盖度以 及冠层结构等生理生态特征, 此外光谱分析还能用来监测湖泊、河流中水华的发生和分布、研究生态系统中CO2和H2O的 通量以及各种逆境胁迫和放牧等对植物生长的影响。

关键词：光谱分析; 植被指数; 色素含量; 光能利用效率; 水华; CO2和H2O的通量

Abstract:

The application of spectral reflectance on research of plant eco-physiology was reviewed. By analysis of spectral reflectance of plant on leaf or canopy levels, concentration of different kinds of pigments, components of xanthophyll cycle, nutrition status, water status, light use efficiency, vegetation coverage and canopy structure of plant under different environments can be fast and non-destructively investigated. In addition, the spectral reflectance can be used to detect algae-bloom in lakes and rivers, carbon and water vapor fluxes in ecosystem atmosphere, and effect of different kinds of stress and graze on plant growth.

Key words: spectral reflectance; vegetation index; pigment content; light use efficiency; algae-bloom; CO₂ and H₂O fluxes
