First,

Course investors, course operators and managers, course turf maintainers and players stand in their own point of view to scrutinize a golf course, will certainly come to different conclusions. As golf course designers, builders and managers, we should have a more comprehensive knowledge of golf course evaluation to guide our daily work.

Evaluating a golf course before we first understand the design principles of the golf course, its basic principles.

From this triangular graphic we can see that the golf course design is centered on the environment, integrating playability, maintainability and ornamental. Protecting the natural environment, utilizing the natural environment, and integrating into the natural environment are the core principles of golf course design.

Playability and spectacle are the needs of the players; maintainability is the needs of the turf maintainers. There is also a need to add two more judgment standards, one is the management of the management of the course, which is the demand of the course business managers; the second is the return on investment, which is the demand of the course investor.

Second, evaluation of the course what are the contents

1, the evaluation of the course investor (investment return)

1) the course itself investment and income indicators;

2) the course to the adjacent industry value of the enhancement brought about by (such as real estate, hotels, recreational projects, etc.);

3) the course to the enterprise to bring the benefits of the other (corporate image, assets listing);

4) social benefits of the stadium (environmental protection, tax, employment, etc.);

2. Evaluation of the stadium's business managers (manageability)

1) reasonable operating costs. Clubs, offices, dormitories, field services, such as electricity, water, oil, gas costs, sewage charges, flood control and drainage, equipment wear and tear, accidental injuries, employee wages, etc..

2) Supporting facilities are convenient and practical. For example, the caddie restaurant is far away from the clubhouse, battery garage, driving range is far away from the clubhouse will bring inconvenience to the use.

3) The smooth operation of the course. Fairway connection is reasonable and smooth, reduce "traffic jam", shorten the playing time, improve operational efficiency. The fairway design is safe and avoids disputes caused by mis-hits. Convenient to hold a variety of events, for the venue to hold the game, should consider the corresponding audience viewing area, rest area, audience parking, awards area, media center, television broadcasting area, fixed camera positions, sponsor advertising positions, exhibits placed in the area and other venues space.

3, pitch lawn maintainer's evaluation (maintainability)

1)Reduce the difficulty of maintenance, reduce maintenance costs. Whether the lawn is easy to maintain, whether the grass species selection is correct, whether it can be safe over the summer and winter; maintenance of the green, hole ± location and number, slope; maintenance of the tee, area size and slope, direction, maintenance of the perimeter; maintenance of the bunker, rain washout, sand replenishment, raking sand and edge trimming; reasonable use of natural vegetation, reduce maintenance costs;

2)Reasonable setup of the battery car, the ball bag car, player and spectator access to reduce the cost and difficulty of lawn management in the access area;

3) Reasonable selection of lawn types;

4) Reasonable selection of landscape plant species;

5) Reasonable selection of irrigation forms (grouping, staffing, system maintenance and repair);

6) Configuration of a reasonable lawn maintenance equipment to reduce the type of equipment and reduce the type of accessories; and

7)Save water, reduce energy consumption;

8)Environmental protection. The impact of the course on the surrounding environment; the pollution of pesticides and fertilizers; the treatment of sewage and waste; the use of water, the construction of ecological and environmentally friendly courses.

4. Evaluation of players (playability and spectacle)

1) Safety: players should be avoided being hit by the ball by mistake.

2) Adaptability to the length of the fairway: too much difficulty is no fun and too little can be boring.

Total length recommendations for the total length of the general course, the professional tees ≥ 7100 yards, the middle tees 5600-6900 yards, the front tees <5200 yards. The difference in total length between the pro tees and the front tees is close to 2,000 yards, adjusted with the number of tees.

Recommended values for length over hazards (tee shots over water hazards): <70 yards from the front tees, <240 yards from the pro tees, and <150-180 yards from the men's amateur tees. As shown below, the distance of the tee shot across the water hazard on this hole is daunting for beginners.

3) Stroke value: Stroke value is a reflection of the relationship between the distance of the shot and the permissible margin of error, depending on the length of the shot, the conditions of the shot, the size of the target, and the severity of the obstacle. The purpose of transforming the stroke value is to test a golfer's ability to hit the ball with different clubs and under different conditions. Its calculation is described in Course Rating.

4) Fairness: defined as the opportunity for the majority of players to complete a normal stroke under normal hitting conditions. For example, multiple different hitting routes with normal flights over obstacle distances are fair, while steep green surfaces with flights over long water distances are not fair.

5) Stroke tempo:.

6) Fluency:It is the speed at which a player can play a full round.Normally, it takes about 4 hours to play 18 holes. If a game takes more than 4.5 hours, it will affect the player's mood and reduce the fun of playing golf. Players will enjoy the course if it flows well and plays fast. In addition, good economic benefits will also bring benefits to the investors of the course. Therefore, fluency is an indicator of course design.

7) Balance: It refers to the same or similarity between the upper and lower half of the course in terms of length adaptability, stroke value, distribution of par, pace of play, etc. The purpose is to consider from the point of view of the course's operation, the course will arrange for a part of the players to play the first half of the course, and the other part of the players to play the second half of the course, and then exchange the site after the half of the course is played. If the players play the nine holes in equal time, the exchange of venues will be smooth. Equal distribution of the difficulty of the upper and lower halves facilitates the stabilization of the players' emotions, and it enables the players to correctly predict the score of the whole course after playing the half.

8) Ornamental fairways: The fairways are richly varied, leaving a deep impression on the players. Each wonderful hole is representative and maximizes the characteristics of the natural terrain. The pursuit of beauty is the nature of mankind, the golf course is integrated into the beautiful nature, the designer will show the beautiful picture to every player, so that the players in the pleasing environment to experience the fun of golf, enjoy the beautiful nature. Since the birth of the camera, the beautiful images of golf courses have been spread to the outside world through photographs, and many players have been attracted by the beautiful images in the photographs, and many people have learned about golf courses through photographs. After the birth of television, with the rapid development of satellite transmission technology and the Internet, the beautiful images of golf courses can be spread to every corner of the world. Strong and extensive visual effects bring great business opportunities to golf courses, which is also an important reason why golf courses are pursuing beautiful images today. Therefore, the pursuit of beautiful visual effects has become a fashion of course design.

9) lawn quality (color, uniformity, density, green speed), site drainage, bunker quality, etc.: lawn color uniformity, complete coverage, no weeds, no pests and diseases; lawn mowing smooth, neat, stripes clear and beautiful, distinct levels; smooth and smooth greens, hardness is appropriate; trees, shrubs, flowers grow vigorously, beautiful colors.

10) Services and supporting facilities of the course (caddies, catering, bathing, etiquette, signage, security, etc.): warm and thoughtful service, generous and decent; a variety of clear, clear guidance, smooth flow; excellent caddie service; front desk, locker, restaurant, departure station, tour of the field is well-staffed, and the quality of service is high.

From the above, we know that the evaluation of a course to consider a lot of factors, and the conditions of the course are very different, it is impossible to take into account in the design of all. The designer can only choose the main factors among the many factors. A course that follows all the principles may not be a good course, a course that does not follow the principles may not be a good course, and a good course may not follow all the principles. If a judge draws one-sided conclusions based on one factor, it will lead to a situation of inconsistency.
