基于遥感技术的林地枯落物持水量研究

林地枯落物持水量的研究已成为森林水文研究的重要方向之一。采用Palsar雷达数据和CBERS CCD光学遥感数据,结合样地调查数据,采用分类和回归树模型对大岭山林场的林地枯落物持水量进行了估测研究。研究结果表明遥感技术可以用于林地枯落物的估测。本研究为今后中国南方开展大面积的林地枯落物持水量提供了一种连续的、可行的和廉价的研究方法。...

Water holding capacity of forest litter is an important research direction of forest hydrology.Remote sensing techniques provide an improve way to study forest litter.Classification and regression tree were used to reconstruct the water holding capacity of forest litter estimation model and predict water holding capacity of forest litter using Palsar and CBERS CCD data with field measured data.The research results demonstrated that water capacity of forest litter could be predicted by remote sensing techniques.The methodology provided a consistent,practical,and inexpensive way for estimating water holding capacity of forest litter over large areas throughout the South China.
