Association between riparian land use and macroinvertebrate community at multiple spatial scales on the upper- and midreaches of Kao-Ping River / 利用不同空間層次評估高屏溪中上游土地利用對水棲昆蟲群聚之影響

碩士 / 國立高雄師範大學 / 生物科學研究所 / 89 / Aquatic macroinvertebrate samples were taken and riparian land-use were measured seasonally on 46 sampling sites in the mid- and upper sections of Kao-Ping River drainage. The objective of this study is to correlate the community characteristics of aquatic macroinvertebrate and selected biotic index with the riparian land-use at multiple spatial scales.
The collected specimen were identified to either family or genus level. Data were arranged as total family, total genus, EPT index, Shannon-Wiener Diversity Index, family- and genus-Hilsenhoff Biological Index, and Benthic Multimetric Index to related with various land-use types. The proportion for each land-use type was measured at field as site scale (30 m-long stream section) and from aerial photo as local scale (1 Km-long stream section). Land-use types were divided into integrated classes and detailed classes.
At least nine orders, 37 families, and 63 genus of aquatic macroinvertebrate were collected in this study. Odonata contained the highest family number, while the Trichoptera displayed the highest number in the collection. Winter and summer collected the highest and lowest number of aquatic insects in 1999, respectively. At any spatial scale, the major land-use type is forest. At site scale, the second highest proportional land-use is bush, while farmland is the second highest proportional land-use types at local scale.
As a whole, few significant linear correlations were observed between aquatic community characteristics and land-use types. However, reverse relationship was identified when EPT richness and total genus number were correlated with artificial land-use. In addition, the Hilsenhoff Biological Index was positively correlated with artificial land-use. These relationships suggested the quality of stream habitat would gradually decrease following the artificial land-use increase.
