Problems from the social, traffic safety and environmental pollution caused by the rapid urbanization have greatly restricted children’s activities in outdoor spaces in most of cities. It is an important part of child-friendly urban planning to create the attractive public outdoor playground and protect children’s right to play freely. This paper firstly carried out relevant theoretical research on children’s outdoor playground, and interpreted the definition and type of children’s outdoor playgrounds, and reviewed the development and research of children’s playgrounds in Germany. Then, taking Germany as an example, based on the detailed explanation and promotion policy on children’s play rights, the design and management of outdoor playgrounds in Germany were analyzed. The planning process of playgrounds includes: 1) setting the general planning objectives and spatial planning quality objectives; 2) analyzing and assessing the site; 3) child participation; 4) developing a playground plan design goals and specific measures. Furthermore, planning and design standards of playgrounds in Germany were reviewed. Since 1971, the first edition of “Residential Area Playgrounds-Outdoor Game Zones and Equipment- Design Principles” has been revised in multiple editions. In September 2012, the latest standard of DIN-18304 was released as “Playgrounds and open spaces—requirements for planning, construction and operation”. Plan, safety and maintenance requirements are more rigorous than previous versions. Until now, Germany has successively released DIN 18040-3 (2014-12), which covers the planning requirements for barrier-free traffic and outdoor facilities in public transportation and open spaces, as well as DIN 33942 (2016-04) which is standard for accessible playground equipment. These standards form an important design basis for the construction and maintenance of facilities in the playgrounds. Subsequently, the eight criteria for creative playground are outlined as the design principles for children’s outdoor playgrounds in Germany as follows: 1) child participation; 2) nature environment as a model; 3) a rest area; 4) space for children’s idea; 5) imaginative diversity; 6) meeting points; 7) the feeling of nature; 8) enriching the status quo. The four main design features of the outdoor public playgrounds were concluded as following. Firstly, playgrounds resembles the natural environment. In Germany, children are seen as part of nature that promoting their creativity and imagination. In the context of the urbanization, on the one hand, the natural environments must be protected to provide children with natural open spaces. On the other hand, it is important to plan and design the attractive and multi-generational playgrounds to make up for the lack of children’s space. The combination of nature and playground has become the consensus of German environmental design. Based on the principle of being close to nature, in planning, playgrounds are usually integrated with parks and green spaces in urban or community; in the design of venues, attention is paid to natural elements. Secondly, the game equipment is dominated by dynamic and autonomous movements. Many children complain that there are no challenges even for new and modern equipments in artdoor public playgrounds. Children want to challenge, stick to themselves and experience the natural environment. They like mounds, sand and water, and hide and seek. The survey from the playgrounds in Germany showed that the core of design is based on preference for children’s activities. Moreover, it helps to promote children’s active sports, fun and challenges. Thirdly, Children participate in design of playgrounds. The participation of children is protected and supervised by law, and children have the right to participate in decisions that affect them. As an expert, children can bring their expertise into playground planning. Children can express their thoughts and aspirations during the planning seminar or construction. We can create safe, stimulating, changeable and attractive places that meet the needs of children by ensuring the full participation of children. Fourthly, Barrier-free playground. Playground for all means that the rides and venues are designed to be barrier-free so that all children can use the playground regardless of physical and mental condition, The concept of barrier-free games attempts to make children with disabilities feel that they are actively involved in the activity Finally, the service and management of outdoor public playgrounds are summarized. Citizens can find any playgrounds by network channels, such as official network and the professional playground portal. The maintenance and management of outdoor playgrounds were led by the government and assisted by the public. Germany has ensured the basic rights and interests of children to play by planning of children’s outdoor public playgrounds with an adventure, game and natural space. Drawing on the experience from the planning, design and management of outdoor children’s playgrounds in German cities, it is of great practical significance to promote the construction of children’s outdoor public playgrounds, and to realize the child-friendly cities and communities in China.
