Abstract
In this paper, we first review the study of urban agriculture, including concept, connotation, characteristic, function and the region of urban agriculture. Many researches found that urban agriculture is located in urban and peri-urban, but it is difficult to distinguish urban and peri-urban. Some of these researches use criteria influencing the size and shape of the peri-urban area, such as the urban influences, official city boundaries, travel time or distance to the centre, it is no clear. So in our research we extract agricultural land and urban land from Beijing SPOT data by remote sensing technology, calculate the model window the ratio of urban land use, according to the ratio of urban land to determine urban and agricultural areas. We evaluated agricultural development level by using Statistical data, we compare the villages or towns range of higher level of development with remote sensing technology, extract urban agriculture area, and draw the conclusions.
