摘要
Commercial agricultural production, which has altered the global distribution of farmland, garden plot, and woodland, cuts links between cities and their neighboring production land, as well as links between production land and the environment, affecting the quality of food supply and inducing ecological crisis. Closely related to urban-rural public welfare and regional ecological security, sustainable food supply, which is featured by various types, local production, and short-chain transportation, is an effective way to address the negative impact of commercial agriculture. This paper clarifies the important role of agricultural and forest land in urban fringe areas through analyzing the functional connotation and spatial bases of sustainable food supply, and proposes a planning strategy for systematic land protection and efficient spatial management in accordance with the current situation of food supply and compound demands in urban areas. Specifically, it consists of: identifying the land and the support space with potential for diversified food production;establishing an agriculture and forestry support network system and integrating it into regional landscape ecological network;guiding the low impact utilization of production units by following the natural process and resource characteristics;enhancing land protection efficiency based on supporting links.
