目的和依据:1)利用马来西亚沙捞越州Lambir山国家公园龙脑香混交林52公顷LTER样地的航空摄影资料,获得52公顷LTER样地5 m网格内森林冠层表面的数字高程数据。2)建立林冠高度剖面图并分析动态相位。方法:利用52ha以上的航空摄影资料,采用航空摄影、信号、地面控制点测量和2.5m或5m网格数字高程的获取等方法,对森林冠层表面的动态变化进行了研究结果与讨论:52ha样地的冠层表面DEM数据(5mx5m网格)显示了冠层的粗糙度,与地形特征相吻合。大型林隙分布在倾向坡的陡坡上,较小的林隙分布在后坡上。提出了一种利用林窗开度分析林窗光照状况的新方法,即林窗内物种多样性不仅可以用林窗面积来评价,而且可以用林窗开度来评价。
英文摘要
Purpose and Justification : 1) To get the digital elevation data for forest canopy surface in a mesh of 5m intervals for 52 ha LTER plot analyzed by using aerial photographs in a 52ha LTER plot, Mixed Dipterocarp forests, Lambir Hills National Park, Sarawak, Malaysia. 2) To construct a canopy height profile and analyze the dynamic phases. This will clarify more precise, local and regional estimates of dynamic phases based on forest canopy surface and can estimate stand biomass and carbon sequestration.Methods : Aerial photography, Signalization, Ground control Point Survey and Acquisition of 2.5m or 5m Grid Digital Elevations on canopy surface were conducted using aerophotographs above 52ha plot (500mxl040m).Results and Discussion : Canopy surface DEM data (5mx5m grid) in the 52ha plot showed the roughness of the canopy and coincidence with topographic characteristics. Large-scale gaps were located on the steep slopes on the dip slope, on the other hands, the smaller gaps distributed on the back slope, respectively. A new method for analyzing gap light condition using openness of canopy cover suggested species diversity in the canopy gap was evaluated not only by canopy gap area, but also by canopy openness.
