The purposes of this study were to investigate the relationships among urban park distribution pattern, residents' choice behaviors, and the quality of residents' outdoor recreation. Junior high school areas were used as study units. Many indices describing urban park distribution pattern were measured for each area. These indices include: (1) Open space ration index that responses construct quantity of urban parks is increased as the raising of urban park construct quantity. (2) Gini coefficient index, C, was used to describe urban parks' area distribution. C value is increased as the urban parks' area distribution is more even. (3) Density index that was used to describe the relationship between the number of urban parks to the area of junior high school is increased as the raising of urban park quantity. (4) Nearest-neighbor analysis that was used to describe urban park distributions. The nearest-neighbor statistic, R, equals 1.0 if the distribution of urban is random. An aggregated pattern or a pattern more regular than random, produces a value less than or grater than 1.0, respectively. (5) Diversity index, H, was used to describe the sort richness and its number of urban parks. H value is increased as the raising of urban park diversity. (6) Diversity index, H', was used to describe the sort richness and its area of urban parks. H' value is increased as the raising of urban park diversity. The questionnaires were then collected from each junior high school area. Statistic methods such as chi-square test, correlation and regression analysis were used to examine the relationships among them. The results are summarized as followed: 1.Residents' choice behaviors did affect by open space ration, gini coefficient, density, nearest-neighbor analysis, diversity index, H and H'. 2.A significant positive correlations were found between residents' outdoor recreation satisfy, gini coefficient, and diversity index, H. 3.Residents' personal characteristics are related to the relationships that among urban park distribution pattern and residents' recreational satisfy.
