In modern agricultural landscapes, the habitats of many species are fragmented. Connectivity is an index to analyze the relationships between pattern and processes in fragmented landscape. Connectivity refers to the qualities of the landscape that facilitate the interaction among local populations of habitat patches. This research tries to explore this central question of agricultural land use and planning. Then, it applies the ecological principles of landscape network theory, security patterns(SP)theory to analyze and map the digital spatial data of De-Zi-Kuo river plain in Yi-Lan County. The primary spatial determinants of agricultural landscape such as existing corridors, river channels, irrigation canals, remnant hedgerows and roads of settlements, etc., are selected to build the appropriate ecological network for sustainable agricultural landscape. Finally, the result of this study tries to suggest the spatial strategies of agricultural land planning and management in future. |
