摘要
首次应用NOAA卫星的AVHRR资料提取天空云遮蔽信息。以多时次可见光波段反射率平均值与相应月份的日照时数建立回归方程,解译哀牢山区日照场时空分布特征。它具有空间分辨率高、资料信息量多,并客观地反映在坡向、坡度、河谷、平坝等复杂地形及不同植被等综合影响下的光资源的时空分布规律,为深入研究山区光资源提供新的方法和科学数据。
In this paper, using NOAA/AVHRR data the information of cloud coverage was extracted for the first time. The regression equation have been established using the mean visible albedo and corresponding monthly mean sunshine durations. Then the features of temporal and spatial distribution of sunshine field in the Ailao mountainous regions have been interpreted. With high space-resolution and large information quantity, the features reflect objectively the spatial and temporal distribution law of light resources under synthetical effect of complex topography (sloping direction, sloping field, river valley, flat etc.) and different vegetation types. A new method and scientific data for making thorough study of light resources in mountainous regions have been provided.
