人们越来越需要生态系统科学来帮助深入了解全球气候变化和土地利用变化对陆地生态系统结构和功能的影响，从小面积（地块）到景观，区域和全球尺度。为了满足这些要求，生态学家在小区尺度上研究了植物生长和碳循环过程，使用生物计量方法测量植物碳积累，并使用气体交换（室）方法测量土壤呼吸。同样在小区尺度上，微气象学家试图通过涡度相关技术来测量冠层或生态系统尺度的CO2通量，该技术揭示了日、季和年循环。数学模型在将生态和微气象过程整合到生态系统尺度中发挥着重要作用，通过与CO2通量测量结果进行比较，这些模型在解释生物计量方法获得的时间累积信息方面进一步有用。为了对这种地块一级的了解进行空间缩放，通过卫星进行的遥感被用来测量土地使用/植被类型分布和生态系统结构的时间变化，如叶面积指数。然而，为了更好地利用这些数据，仍然需要进行调查，考虑生态系统的结构和功能及其过程，特别是在地形复杂和植被镶嵌分布的山区。为此，我们已经建立了一个新的跨学科的方法命名为“卫星遥感”，其目的是连接生态学，遥感和微气象学，以促进生态系统功能的研究，在情节，景观和区域尺度。
There is a growing requirement for ecosystem science to help inform a deeper understanding of the effects of global climate change and land use change on terrestrial ecosystem structure and function, from small area (plot) to landscape, regional and global scales. To meet these requirements, ecologists have investigated plant growth and carbon cycling processes at plot scale, using biometric methods to measure plant carbon accumulation, and gas exchange (chamber) methods to measure soil respiration. Also at the plot scale, micrometeorologists have attempted to measure canopy- or ecosystem-scale CO2flux by the eddy covariance technique, which reveals diurnal, seasonal and annual cycles. Mathematical models play an important role in integrating ecological and micrometeorological processes into ecosystem scales, which are further useful in interpreting time-accumulated information derived from biometric methods by comparing with CO2flux measurements. For a spatial scaling of such plot-level understanding, remote sensing via satellite is used to measure land use/vegetation type distribution and temporal changes in ecosystem structures such as leaf area index. However, to better utilise such data, there is still a need for investigations that consider the structure and function of ecosystems and their processes, especially in mountainous areas characterized by complex terrain and a mosaic distribution of vegetation. For this purpose, we have established a new interdisciplinary approach named ‘Satellite Ecology’, which aims to link ecology, remote sensing and micrometeorology to facilitate the study of ecosystem function, at the plot, landscape, and regional scale.
