Aiming at various factors currently affecting and restricting the demand for leisure extreme sport, the author selected such two factors as the degree of participation and the cost for relaxation to establish a model of the demand for leisure extreme sport. By basing their research subject on State Forest Park at Culai Mountain in Shandong, a typical place for leisure extreme sport, on the basis of acquiring data via questionnaire survey, and by using SPSS (a statistic tool) and proving via grey correlation degree ordering, the authors performed some analyses, and revealed the following findings: the de-gree of participation and the cost for relaxation are the most important factors that affect leisure extreme sport; the model of the demand for leisure extreme sport is rational and feasible to a certain extent.
