【摘要】：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。
[Abstract]:Ecometrics provides basic technical support for ecology, geography, forestry, wildlife, etc. It is increasingly important to develop new ecological surveying techniques adapted to the development of these disciplines, especially with the rapid development of biogeochemistry.The development of three-dimensional biophysical chemical ecological measurement technology has become a hot research topic. However, the current mainstream remote sensing measurement technology is still unable to achieve high efficiency and accuracy.The development of hyperspectral lidar technology makes it possible to solve this problem, which is based on the continuous measurement of three kinds of single-tree hyperspectral laser radar data to achieve the inversion of photosynthetic effective radiation.The three dimensional distribution of chlorophyll content and nitrogen content and their diurnal variation trend were verified.The experimental results indicate that with the maturity of hyperspectral lidar, three-dimensional biophysical chemical ecological measurement will be established, and the corresponding three-dimensional biophysical and chemical ecological measurement technology will further promote geography and ecology.The development of biogeochemistry and even earth system science.
