生态测量学为生态学、地理学、林学、野生生物学等提供基础的技术支撑,开发适应上述学科发展的新型生态测量技术日渐重要,尤其随着目前生物地球化学的快速推进,开发三维生物物理化学生态测量技术成为当前的研究热点,然而当前的主流遥感测量技术仍无法做到高效准确。高光谱激光雷达技术的发展为解决该问题提供了可能,这也通过基于连续测量的3种单木高光谱激光雷达数据实现反演光合有效辐射、树冠叶绿素含量与氮含量的三维分布及其昼夜变化趋势得到验证。实验结果预示随着高光谱激光雷达的成熟,三维生物物理化学生态测量学将得以建立,相应的三维生物物理化学生态测量技术将进一步推动地理学、生态学、生物地球化学乃至地球系统科学的发展。 Ecometrology provides the basic technical support for ecology, geography, forestry and wildlife biology. It is increasingly important to develop new ecological measurement techniques to adapt to the above subject development. Especially with the rapid progress of biogeochemistry at present, the development of three-dimensional biophysical However, the current mainstream remote sensing measurement technology still can not be efficient and accurate. The development of hyperspectral Lidar technology has made it possible to solve this problem. This also achieved the inversion of photosynthetically active radiation by three single-wood hyperspectral Lidar data based on continuous measurement, the three-dimensional distribution of crown chlorophyll content and nitrogen content and its diurnal The trend of change has been verified. The experimental results indicate that with the maturity of hyperspectral laser radar, three-dimensional biophysiometrics will be established and the corresponding three-dimensional biophysical and chemical ecology measurement technology will further promote the development of geography, ecology, biogeochemistry and even the earth system science .
