At the same time, the biomass of species-rich community was more sensitive to the change of environmental conditions, while communities with fewer species had a little change in biomass.2 There were a total of 87 vascular plant belonging to 27 families and 68 genus in the six communities. Most species had a narrow distribution and a lower local abundance, while few species had a wider range and higher local abundance, and this distribution trends varied in different communities. The endemics were positive correlation to y diversity.

Under the excitation of 488 nm light beam of argon ion laser source, single suprahelical species could be observed with the aid of a common microscope due to the strong scattered light emitted by the suprahelical species. By capturing the RLS images of the single suprahelical species with a cooled charge coupled device camera, and analyzing the RLS data, herein an RLS imaging method of DNA was proposed based on the linear relationship between the counts of suprahelical species in the detection focus plane and the concentration of DNA in nanograms.

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.

应用生育地因子评估树种之生态地位，能解决统计实证方法在空间异质性使用的限制，并可同时评估多种树种，因此可应用在造林树种之选择，亦可应用於崩塌地复育造林树种之选择，以及林相改良造林树种之选择，在收集更多树种属性与空间分布资料后，配合此评估方法，未来更可模拟出台湾森林之动态，以及评估环境变迁对台湾森林所造成的影响。
