Abstract: | The models for landscape connectivity are distinguished into models for line connectivity, vertex connectivity, network connectivity
and patch connectivity separately. Because the models for line connectivity, for vertex connectivity, and for network connectivity
have long been studied and have become ripe, the model for patch connectivity is paid special attention in this paper. The
patch connectivity is defined as the average movement efficiency (minimizing movement distance) of animal migrants or plant
propagules in patches of a region under consideration. According to this definition, a model for landscape connectivity is
mathematically deduced to apply to GIS data. The application of model for patch connectivity in the new-born wetland of the
Yellow River Delta shows patch connectivity has a negative interrelation with human impact intensity and landscape diversity. |
