%X Ecological corridors have many functions such as biodiversity conservation, contamination filtration, erosion prevention and flood control. As an important element in landscape planning and design, ecological corridors can be used to reduce the negtative impact of landscape fragmentation. According to their different structures and functions, ecological corridors can be classified into linear, strip, and stream corridors. The planning and design of ecological corridors are mainly composed of several key elements including number, context, width, connectivity, component, key points and areas. The width of ecological corridors is usually an uncertain parameter depending on the complexity of the structures and functions of the ecological corridors themselves, and it is the function of a number of parameters such as target species, vegetation, functions of corridors, surrounding land uses and length of corridors. Scientific and appropriate width of ecological corridors should be determined based on the research of defferent ecological processes within the corridor. Starting from the analysis of the structure and function of landscape, this review analyzed the width of ecological corridors and its determinants from the perspective of biodiversity conservation; appropriate ranges of width were summarized from several case studies. Principles to define width were also proposed.
