Promoting human health is a basic value of landscape architecture. It is theoretically feasible to rebuild the link between children with nature-deficit disorder and nature via artificially-made natural environment. This paper explored the relationship between children’s health and nature from the perspective of landscape architecture theories and practices. First, impact of nature-deficit disorder on children’s health; second, basic appeals of children with nature-deficit disorder were sorted out; finally, specialized gardens for children with nature-deficit disorder under the instruction of the above theories were designed.
