北京工人体育场草坪质量分析

The Quality of Turf in Beijing Workers′ Stadium

针对北京工人体育场草坪足球场的主要质量指标，即足球弹性、场地硬度和摩擦系数进行了评价，并对影响这些指标的因素，即土壤物理化学性质、草坪性状进行了一个赛季的调查。结果表明大多数质量指标已达到国际标准，而土壤物理性状的奠定和改良对于改善和维持草坪运动质量起着关键性作用；在保证这些质量标准的前提下，为延长绿期而改变草种组成有较大的余地；分析了在我国推广质量标准的可能性。

The playing quality of turf in the Beijing Workers′ Stadium was investigated in the game season of 1996. In general, the indices appraised, including ball bounce, surface hardness and friction, have met the international standards. It was noticed that soil compacting was a major factor bringing about adverse effects to the turf, and, therefore, an improvement in the composition of the soil and overseeding with cool-season grasses would improve the stability of the turf and keep the sport ground green in a prolonged period.
