| Summary: | 碩士 === 國立屏東科技大學 === 農村規劃系 === 93 === The purpose of this study is to keep a record of process and method of rural ecological study. Through actual participation, the research includes theoretical estimation and practical confirmation. It comprehends biodiversity index of plantations, birds, aquatic insects, landscape, spatial structural index and the corresponding environmental quality database. Analyzing the result of aquatic insects and proposing a guideline of developing rural biodiversity. The researcher wishes to provide a useful reference for future ecology related research.
The result shows that the biodiversity of aquatic insects of rural landscape cannot be presented in the 100m-landscape diversity. Furthermore, the cross-section of ditches in spatial structural index and the aquatic insects diversity index have positive, including requirements of plantation structure, verging plants, riverbank, enclosing of space, river depth and soil components. Also, spatial structure index seems to quicken restore of aquatic insects population. The ‘Rural Ditch System’ should be taken into account as a whole while considering the development of rural biodiversity. Issues such as river quality, hydrology, DO、pH、SS、BOD, water-table and current speed are essential and ignorable. Also, the ‘ditch spatial pattern’, namely the maintenance of curving route of ditch surface, of vertically concave and convex riverbed with diversified substances, and of three horizontally parts including the edge, the ecotone and the aquatic, is crucial. These are all major conditions that affect rural biodiversity.
