Abstract
Studying the temporal change of the relationship between landscape and species is not only an emphasis in landscape ecology studies, but a important information for landscape designing and planning. This study used 5 parts to figure out their seasonal changes: (a) landscape, (b) landscape structure, (c) trees who have seasonal phenology changes in woodland, (d) bird community, and (e) the relationship between landscape structure and bird community.
There are 25 samples in Mei-Feng farm. This study serveyed bird data monthly from may 2009 to April 2010, and acquired landscape images by low-attitude aerial photography at the same time. We used ArcGIS 9.2, ERDAS IMAGINE 9.3, eCognition 4.0 to change landscape image to digital data, and used MANOVA and Spearman rank-order correlation to analyze data. The definition of season is spring (Mar.-May), summer(Jun.-Aug.), autumn(Sep.-Nov), and winter(Dec.-Feb.). The conclusion is:
1. There are different relationship situation between landscape structure and bird community among 4 seasons, specially, LCTs which are crop, grass, road, building, leaf-fall, and full leaf can effect bird community the more in each seasons.
2. In the mountain farmland area, birds are more sensitive to landscape structure in winter then in other seasons. Consequently, if a study in this kind of area are lacking of budget or time, seasons can be separated as winter and not-winter to save money and time.
3. Using landscape structure to discuss landscape seasonal changes represents more particular than using landscape which only describe by area of LCTs. In addition, classifying LCTs more particular and more suitable to the research purpose can make the results more explainable.
