Agroforestry Systems in Northern Temperate Zone and Productive Perspectives
As the traditional land application system, agroforestry systems had developed quickly in decades for the demand of agriculture, forestry and sustainability science under the background of global changeing. In this review, the authors described the classification of agroforestry systems in Europe, China and North America based on their components, spatial&temporal arrangement, function, and agro-ecological zone. Then, this paper discussed the productive characteristics of crop and tree components, especially for elevated CO2. Some directions considering research focuses and problems are suggested in China.
