山地在维持生物多样性、调节区域气候和涵养水源等多个方面具有非常重要的生态服务功能。由于存在高度的时—空异质性,山地地表生态参量的反演面临更多理论和技术上的难题,也对定量遥感的发展提出了新的要求。梳理了山地地表生态参量遥感反演的研究进展,讨论了进一步提高山地地表生态参量遥感反演能力的关键理论、技术及存在问题。只有模型、观测和数据处理方法3个环节的共同进步和有机结合才能推动山地定量遥感继续向前发展。反演山地生态参量不仅需要已有理论和技术的提升,同时还需要方法论上的突破。 |

Mountainous areas provide diverse ecosystem services in many aspects,including biodiversity maintenance, regional climate regulation and water conservation.The retrieval of biophysical variables in mountainous areas faces more challenges in technology and theory compared to that in flat terrain.These challenges derive from the significant surface heterogeneity and the lack of appropriate models for radiative transfer and ecological process.The related research progresses and key theory and techniques in montanic biophysical variables retrieval were reviewed in this paper.Further improvement of retrieval accuracy calls for paradigm shift in modeling,observation and data processing in mountainous areas. |
