Urban parks in the modern sense originated in the United States. The founder of American landscape design, Frederick Lau Omsted, proposed a great idea of building parks in the city. As early as more than 10 years ago, he and Walker jointly designed New York Central Park (1858-1876). This event not only opened the way for modern landscape design, but more importantly, she marked the arrival of the city's public life landscape. Parks are no longer a luxury for a few people, but a pleasure for the general public.
