Abstract
By comparing the roles of three landscape groups (the two different edge types as well as all edges grouped together) in explaining plant species richness (at alpha and gamma level) and community turnover (at beta level) in the sampled landscape squares, we found that density index of non-crop field edges surrounded by contrast land use is an effective indicator of species diversity at beta and gamma level. This study suggested that field margins surrounded by contrast land use shall be considered as a priority landscape element in agricultural edge network design, whereas simply using the density of all field edges to indicate species diversity without separating the different effects of various edge types shall not be recommended.
