林隙生态机理已成为现代森林生态学研究的热点，尤其是林隙内光照条件的变化对树种更新和生长具有重要的生态效应。但是、由于林隙结构极为复杂，难以精确地测量林隙上方和周围树冠空隙的透光情况。为此，本文应用鱼眼全景摄影方法拍摄了林隙结构的全景图象，建立了在像片上直接计算林隙遮蔽效应的数学模型，并在林隙全景像片上绘制出太阳视轨道，就可以定量和直观地表述林隙内日照条件的变化规律。
The mechanism of gap ecology has become a hot research topic in modern forest ecology, especially the change of illumination conditions in the gap has an important ecological effect on tree species renewal and growth. However, due to the extremely complicated structure of the gap, it is difficult to accurately measure the light transmission of the crevice above and around the gap. Therefore, in this paper, the panoramic image of the gap structure was filmed using the fisheye panoramic photography method. A mathematical model was established to directly calculate the shadowing effect of the gap in the gap and to draw the solar orbit on the panoramic image of the gap. Quantitative and visual description of the gap conditions of sunshine conditions change.
