On maintaining ecological balance and promoting economical development, it is necessary to strengthen the spatial relation among the landscape patterns whose functions are similar. The growing awareness of the adverse effects of habitat fragmentation on natural systems has resulted in a rapidly increasing number of actions to reduce current fragmentation of natural systems as well as a growing demand for tools to predict and evaluate the effect of changes in the landscape on connectivity in the natural world. For promoting and positioning functions of each landscape unit in the whole Taiwan island, systematically studying characteristics of landscape patterns in the research areas, and identifying energy routes of landscape function flows, this study chooses the basic regionalism units as the research areas such as Wuxi watershed to analyze connectivity traits among network nodes with single function as well as spatial interactions of different functional networks based on landscape function network establishment. Then from the aspect of consolidating network configuration to strengthen landscape functions, this study puts forward some strategies to optimize landscape patterns. Through linkage analysis of network nodes, it is found that urban function network structure is better than ecological function network in Wuxi watershed, and most urban function sub-nodes are located around the urban function centers, which can allow landscape functions export and transmit. The connectivity of ecological function nodes is similar, but the first and second level nodes such as Hongxiang and Gaomei wetlands are isolated and less connected, so this study proposes to consolidate function transmitting routes and highlight significance of main transferring nodes like Erzhaishan and Beikengzi aiming at optimizing ecological landscape in Wuxi watershed.
