Landscape diversity of Paerargyrops edita Tanaka stock in Minnan-Taiwan Bank Fishing Ground

The landscape elements with barycenter of fishing ground of kinetic energy were established based on the parameters of catch per unit effort (CPUE) of each fishing area and the distance between fishing center and each area from the special survey data of Paerargyrops edita Tanaka in Minnan-Taiwan Bank Fishing Ground during July 1998 to June 2000. Using landscape diversity index and factor analysis, we studied, the space structure of Parargrops edita Tanaka's landscape diversity and its relationship with marine environment factors. We also explored the interaction relationship between spatial distribution pattern and ecological processes, which revealed the ecological condition and spacial variability characteristics of Paerargyrops edita Tanaka in Minnan-Taiwan Bank Fishing Ground. Water temperature, foraging and reproduction were the main factors for the variations of landscape pattern of Paerargyrops edita Tanaka.
