本研究主要是运用资料收集法、对比法、归纳法、对多人同场对抗设防命中得分类项群防守共同性进行时空理念的分析与整合。从整体防守、横向区域防守等方面分析,得出了该项群的防守理念为:防守是第一位的,进攻是第二位的;赋予了防守时间特征,构成“以球体为主,人、球体、区域、时间兼顾”的防守原则与理念。研究该项群的防守纵向区域防守的差异性,既能够发现和揭示该项群防守的特点与规律,又能丰富和完善该项群攻防理论体系。 In this study, the methods of data collection, comparison and induction are used to analyze and integrate the concept of space-time in the commonalities of defensive and hitting defensive groups in the same field. From the overall defense, cross-regional defense and other aspects of analysis, concluded that the group’s defense philosophy as follows: defense is the first one, offensive is second; given the defensive time characteristics, constitute People, sphere, region, both time "defensive principles and concepts. Studying the difference of defensive longitudinal defense in this group can not only find out and reveal the characteristics and rules of defense of this group, but also enrich and perfect the theoretical system of attack and defense.
