森林蓄积量遥感估测的研究进展

Research Progress in Estimating Forest Stock Amount with Remote Sensing

传统的森林资源调查是一项周期长、任务重、劳动强度大,需大量经费的工作。随着遥感技术广泛应用于森林资源调查工作,特别是森林蓄积量的遥感估测,将比传统方法省时、省力,节约经费。目前,利用遥感进行森林蓄积量的估测研究已取得了一系列重要进展,文章则简要综述了国内外在光学遥感和微波遥感范围内的森林蓄积量遥感估测方面的研究进展,认为利用遥感技术进行森林生物量估测对于了解和监测全球生态系统对气候变化和人类活动的反应具有重要的意义。

The traditional forest resources investigation is a kind of work with long cycle , arduous tasks, heavy labor intensity and needing massive funds. With remote sensing technology being widely used in the investigation of forest resources, especially in the remote sensing estimation of the forest stock volume, remote sensing method can save time, work and budget in comparison with the traditional method. At present, a series of important research progress in the estimation of the forest stock volume by using the remote sensing has already been made. The research progress in the remote sensing estimation of the forest stock volume within the scope of the optical and the microwave remote sensing both at home and abroad was summarized. Furthermore, it was of great significance to carry on the estimation of the forest biomass by using the remote sensing technology for understanding and monitoring the climatic change and the human activities under the effect of the global ecosystems.
