Over the past century, the global average temperature has increased by 0.6 Celsius, and the average temperature in Taroko National Park has also gradually increased over the past 10 years. Global warming also affects global climate change. Since the 21st century, many extreme weather and climate changes have been observed. Taiwan is facing the impact of climate change like most other parts of the world, too.Understanding biodiversity is one of the most important aspects of natural resource conservation. Taiwan hosts rich biodiversity resources and endemic species, but the basic classification and ecological data for many organisms are still scanty. Human activities have inadvertently resulted in the destruction of natural resources due to the lack of knowledge of these data. Among animal groups, Lepidoptera is one of the groups with high species diversity and research value. Moths are highly sensitive to climate and environmental changes. The distribution of moths may produce different cluster combinations with different altitudes, different forest phases, and different climate changes. The present study uses ultraviolet lamps to regularly investigate monthly changes in the number of moths, with the hope to that use the results of this study to understand the changes in moth diversity across various altitudes in Taroko National Park.We set up eight main sample sites to investigate moth resources from altitudes of 100 meters to 3,000 meters and calculated the moths’ species richness, the commonly used diversity index— Simpson's index (D') and Shannon-Winner index (H') to explore the distribution of moths at different altitudes. The results showed that the species richness of moth species decreased with increase in altitude, showing a linearly decreasing relationship. Compared to the data collected 10 years ago, except for the Xiao Feng Kou area located at high altitude, the diversity at all other altitudes has a significant downward trend. Finally, this experiment attempts to establish indicator species representinghabitats of different altitudes. By monitoring the fluctuations of these indicator species under different environmental conditions, we can not only understand large-scale environmental changes, but also explore local subtle environmental changes.海拔蛾類群聚物種多樣性指標物種保育Altitudespecies compositiondiversityindicator speciesconservation學術論文
