1) The method to detect canopy dynamics by using aerial photograph was applied in various forest types, and found that it is applicable also for devergreen forests and operated forest by shelterwood system.2) The technique to combine tree dynamics and canopy dynamics has been developed for a tree species, and its effectiveness in analyzing the tree demography has been validated.3) Some ecosystem parameters, such as biomass, its production, tree recruitment and mortality were related to canopy dynamic features. The canopy height could be used as the effective parameters to estimate these ecosystem parameters in larger scale. Also, the canopy height distribution could be applied to estimate the food biomass of some herbivours in landscape leverl.4) GIG system was applied to assess combine the ground trouth, analyzed results of aerial photographs and satellite data, and its effectiveness was validated. Also, a new trial usig a laser profiler to detect 3-dimentional canopy structure was applied, and got the highly expecting results.

1) 将航空摄影检测冠层动态的方法应用于各种森林类型，发现该方法也适用于常绿林和防护林系统经营林。2) 针对树种开发了树木动态和冠层动态相结合的技术，并验证了其在分析树木人口统计学方面的有效性。3) 一些生态系统参数，如生物量、其产量、树木补充和死亡率 与冠层动态特征相关。冠层高度可以作为更大规模估计这些生态系统参数的有效参数。此外，冠层高度分布还可用于估算景观水平下某些食草动物的食物生物量。4)结合地面实况、航空照片和卫星数据分析结果，应用GIG系统进行评估，并验证了其有效性。此外，还应用了激光轮廓仪检测三维冠层结构的新试验，并得到了令人期待的结果。
