摘要
The urban river corridor is an important ecological space that is known for its landscapes and ecological continuity. Compared with the natural river, the urban river is seriously affected by human activities, which are constructed with the hope of recreating a similar natural environment and are uniquely designed so that ecological specialists, landscape experts and scientists could study both the surrounding environment's ecological effects and the continuity degree of the river corridor area. A system, including 10 indices urban river corridor, is established. This assessment method adapts the Analytic Hierarchy Process, GIS data analysis and GIS space technology, and is combined with these methods based on quantitative and qualitative analyses. Using the results obtained by studying the Suzhou River Corridor and the assessment of ecological continuity is completed and the spatial distribution characteristics are approved, thus it allows future development throughout the corridor. Eventually, a development policy is proposed. Firstly, a method to improve the landscape connectivity among the river's greenways is needed. Secondly, a high value area with ecological continuity related to the river greenway is planned along the river greenway. Thirdly, a sufficient natural area is needed to give the area a river corridor influence, maintain the river's ecological continuity, and keep this natural area undisturbed by zoning. Lastly, the plant species distribution need to link ecological traits and landscape matrix. The study of this assessment method provides a rational development path and decision-making basis for the construction of healthy and sustainable urban river corridors.
