Abstract:To quantify the ecological consequences of the landuse scenarios of Liaohe Delta Wetland, LEDESS model (Landscape Ecological Decision and Evaluation Support System) was employed to model effects of the scenarios on breeding carrying capacity (BCC) of indicator species (i e Red crowned Crane and Saunder‘s Gull) The result indicates that, wetland mitigation (scenario A) can both greatly improve the breeding carrying capacity of Red crowned Crane and Saunder‘s Gull except maintaining “no net loss” of...
