This paper introduced the history, development, and major accomplishments of the urban and community forestry movement, highlighted the economic, ecological, environmental, and social values of forests and trees to communities, and discussed issues and trends of the urban and community forestry program in the United States.展开更多

On the basis of eco-service functions of community garden,this paper selected 14 such gardens in Los Angeles and studies them by field survey. It researched the response of diversity of urban vegetation varieties and distribution pattern to planters' ethnic background and construction mode,then it analyzed its implications for China's urban green space construction and leisure agriculture. A total of 439 varieties of plant were studied,indicating that community garden is an important species pool of urban ecosystem; it can maintain rich native taxa resources; plant function is mainly edible plant, which plays a great role in protecting ethnic traditional culture and regional native culture; landscape structure and function of vegetation are influenced by ethnic background and construction mode. Researches show that the community garden,as the intersection landscape of ecological diversity and cultural diversity,is a feasible construction mode for realizing urban green infrastructure construction and leisure agricultural development. China should learn from this experience,take into consideration interested parties when making green space planning and conducting eco-vegetation construction. This is of great significance to launching urban eco-vegetation construction and developing leisure agriculture in China.Community garden is a popular vegetation landscape mode with production,ecology and life functions.
