| Summary: | 碩士 === 環球技術學院 === 環境資源管理所 === 97 === With the case study of the Jiaosi Taiwan Keteleeria Natural Protected Area, the Chatienshan Nature Reserve, the Syuejian Recreation Area, and the Huanshan Burned Area, this research analyzed the data from monitor the change of insect communities. Besides, this research also studied the effect of environmental factors on the insect community, the comparison of basic insect communities and Malaise trap insect communities, and relevant analysis of alpha diversity Indices. Through the diversity indices and the species abundance models, this research expected to have further study on the insect community as a reference for species monitoring inventory. From the result, it was concluded that: (1)There are totally 13 orders,72 families and 89 species in Jiaosi Taiwan Keteleeria Natural Protected Area, 19 orders,203 families and 274 species in Chatienshan Nature Reserve, 15 orders,226 families and 335 species in Syuejian Recreation Area, 18 orders,240 families and 327 species in Huanshan Burned Area. (2) From species accumulative curve in the Jiaosi Taiwan keteleeria Natural Protected Area, the Chatienshan Nature Reserve, and the Syuejian Recreation Area, it showed that with investigate increase of number of times tend towards stability gradually already. but from the species accumulative curve in the Huanshan Burned Area, it showed the species of Huanshan Burned Area still developed. (3) With the analysis of insect fauna diversity by the method of family-level biological diversity, it showed that the percentage of both Order Diptera and Order Coleoptera were the highest in these four research areas but the situation of trapping the insects of Order Hymenoptera and Order Psocoptera were different. Therefore, it was suggested to use the insects of Order Hymenoptera and Order Psocoptera as our indicator communities for long-term monitoring. (4) Form various diversity indices, it was concluded that the community of insects would be different according to the change of seasons. (5) It was limited for the use of diversity indices and species abundance models. Under the same index and model, it perhaps appeared entirely different insect fauna. It was suggested that it could consider the composition of insect communities with different functions in different habitats for future researches in order to have a deeper study on the ecosystem structure. (6) As studying the difference between basic insect communities and Malaise trap insect communities by actually-trapped family numbers, it was found that such difference was not significant. However, the results of diversity index and species abundance model were not entirely same. Besides, which model was suitable was not necessarily related to the total number of individuals but correlated to the structure of communities and to the consideration of distributions of species numbers and total individual numbers in the whole community. (7) There were almost significantly positive correlations among Shannon Information Statistic Index (HSW), Mclntosh Species Abundance Index (DM), Simpson Species Abundance Index (DSM), Shannon Evenness Index (ESW), Mclntosh Evenness Index (EM) and the value of α in the logarithmic series, but significant negative correlation for Berger Species Abundance Index (DBP). For the choice of diversity index, this research thought that Berger Species Abundance Index (DBP), Shannon Information Statistic Index (HSW), Q statistic value and Shannon Evenness Index (ESW) were those diversity indices extremely worthy of utilization.
