Relationship between the Number of Staying Visitors and the Total Visitors-hour on Amenity Grassland

Abstract

The man-hour unit is suitable for treating the recreational impact quantitatively upon turf or amenity grassland. But it consumes a lot of time and humanpower to count them. On the other hand, the number of staying visitors on the site can be counted very easily. In this study the relationship between the number of staying visitors and the total visitorshour were investigated based on 32 field surveys for the convenient estimation of recreational impact.
The theoretical consideration revealed the relation as follows:
T=D·R·V=A·V
in which T is the total visitors-hour at a given day, D, the mean residence time, . R, the turnover rate, V, the maximum number of staying visitors of the day, and A, the mean
The measured value of the mean appearance time varies with the size of the service area of the site. It takes the value 7.0-8.9 in residential areas, 6.2-7.0 in the Yodogawa riverbed park, 5.4-6.4 in comprehensive parks, and 4.2-5.0 in suburban areas. We can estimate the total visitors-hour on a given site by multiplying the number of staying visitors times this coefficient. appearance time.
