Study On Synthetic Assessment System Of Turf Quality

In this paper, sixty varieties of three cool-season turfgrass species including Tall Fescue , Perennial Ryegrass and Kentucky Bluegrass were tested for assessment of turf quality by using the synthetic judgement of fuzzy mathematics A brief and to the point assessment system for turf quality were given. Main results were shown as follows: 1. The indexes of assessment system were selected as density, texture, colour, uniformity, covering ,rebounding. 2. In this paper, the value of every index is got from experiment or calculation, so it can improve the accuracy of the result of the turf quality. 3. Through T.L. satty?s method of 1-9 scales of Analatical Hierarchy Process (ATP), the weight ratio of matrix were got and it can calculate the maximum characteristic solution, then it can be regarded as the satisfying value of weight. 4. According to the value of experiment or calculation, the value of synthetic judgement were gained through the synthetic judgement of fuzzy mathematics. Last, contrast the quality standards of turf, the grade of turf quality were defined.
