【摘要】 本文通过对足球场和高尔夫球场的现场测定取样和运动场草坪草践踏的不同研究方法，制定了一个简单、量化的耐用强度模型。通过对几个简单、典型的草坪草的指标测定，就可获得该运动场草坪的耐用强度。 1．采用土壤强度作为践踏的指标是经过三种方法试验和方差分析 检验，论证的比较典型和具代表性的。 2．利用模糊数学中的笛卡尔积集的相同性建立关系矩阵，通过海 明距离法可获得生长因素系数，再利用土壤强度变化范围，建 立关系模型，即为耐用强度模型。 3．将践踏后运动场草坪进行人工和自然的对照培育措施处理可以 用来应证耐用强度的数学模型，为今后利用计算机科学化、系 统化地管理运动场草坪提供了理论依据。 运动场草坪的耐用强度不是简单地等于践踏强度和培育操作的强度，主要还要从运动场草坪的生理承受能力出发。选择水分，光照和养分作为研究运动场草坪的重要生长因素是具有典型性和代表性的。 在试图产生培育制度前应该确定草坪的特殊功能，草坪的主要功能是土壤稳定作用的地方，它们所需的培育操作的数目和力度是比较低的。但对于运动场草坪包括高尔夫的果岭、发球台、球道草坪和其它运动场草坪一般接受比大多数庭院草坪更频繁的刈剪和更严重的践踏。因此，各种培育操作的数目力度和频率通常也是很高的。 利用对现有运动场草坪耐用强度的研究，希望能够给今后现代化管理运动场草坪提供一定的理论基础，而且也可以使运动场草坪的评价更科学化。更多还原

【Abstract】 A model of durable tolerance of sport turf was established in this study according to on-the-spot sampling, together with and different treatments of trampling. The durable tolerance of sport turf was obtained based on determinations of the several indexes of turf grass. 1. The index of soil tolerance was typical and representative, which was examined through three ways (treatments) and statistical analysis 2. The relation matrix was set up according to the similarity of the Dical muster in Fussy mathematics, the growth coefficient was obtained according to Haiming Distance, together with the ranges of soil tolerance, the relation model, namely the model of durable tolerance was established. The additional and natural maintenance and improvement management after treading can be matched to this model, thus, the scientific and systematic management on turf will be fulfilled by depending on computer. The durable tolerance of sport turf does not simply mean the treading intensity and management efficiency, the typical and representative physiological factors affecting the growth of turf, such as water, light and nutrients should be paid more attention. The function of the turf should be ensured, mostly the turf was used to control soil, and the management is extensive for this type of turf, but as for the Golf Green, Tee and Course, the management is more intensive, due to frequent cutting and treading. Therefore, this study was conducted to offer basic ideas for efficient management, and scientific evaluation on sport turf.更多还原
