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. Results are listed as follows: (1) The distribution characteristics of fish population differed obviously in months: the fish population distributed most extensively in August, most equably in November, and most concentrated in February and December, while the fish population had the strongest ability in occupying fishing ground in September. (2) Different populations had various distribution characteristics: The reproductive population had the smallest distribution range and reproduced concentratedly; however, this population had weakest ability to occupy fishing ground. Juvenile fish had the smallest average distribution range and was well-distributed; however, they had the strongest ability to occupy fishing ground. Feeding stock distributed widely and uniformly and foraged dispersedly; they also had the strongest ability to occupy fishing ground; while during September to November fish group's average distribution range became smaller, and fish group concentrated gradually with weak ability to occupy fishing ground. (3) The fish comprehensive landscape index referred to CPUE index with space structure, which reflected the CPUE of fish population from ecological levels; and the ranking was as follows: August, June, July, September, October, November, May, January, April, March, February and December. (4) Diversity index, evenness index and dominance index indicated the distribution range, uniformity coefficient and space competitiveness of fish population, respectively. We observed a positive association between diversity index and evenness index. (5) Water temperature was the main factor that affected the landscape uniformity; foraging was the major factor for enlarging fish population's landscape diversity and dominance, while reproduction factor was the important factor for reducing fish population's landscape diversity and dominance. Water temperature, foraging and reproduction were the main factors for the variations of landscape pattern of Paerargyrops edita Tanaka.
