【摘要】：我国西北部旱区城郊农业承担着城市生态屏障和经济发展的双重职能。传统的城郊农业功能已经不能够适应现代城市的城乡一体化布局和功能互补的需求,其功能定位已由单一的生产服务功能向生产、生态、景观与文化等多功能综合发展的方向转变。以甘肃省庆阳市西峰区为例,根据其自然资源特征和城郊农业发展现状及其功能定位与空间布局,从系统的功能耦合、产业耦合和空间耦合角度,设计了高效林草植被恢复生态保育模式、高质粮-果-草-畜耦合生产模式和休闲观光文化拓展模式。通过这3种模式的综合应用,以水土涵养和生态保育为基础,高效、优质生产为导向,农林牧耦合为手段,在西峰区城郊形成集高效、集约、生态、产业化、科技化为一体的现代城郊农业体系。
[Abstract]:The suburban agriculture in the arid area of northwest China bears the dual functions of urban ecological barrier and economic development. The traditional function of suburban agriculture can no longer meet the needs of urban and rural integration layout and complementary functions of modern cities. Its function orientation has changed from a single production service function to a multi-functional comprehensive development direction such as production, ecology, landscape and culture. Take the Xinfeng District of Qingyang City, Gansu Province as an example. According to the characteristics of natural resources, the status quo of agricultural development in suburbs and its function orientation and spatial layout, the ecological conservation model of high efficiency forest and grass vegetation restoration was designed from the perspective of system functional coupling, industrial coupling and spatial coupling. Through the comprehensive application of these three models, it is based on soil and water conservation and ecological conservation, high efficiency and high quality production. The coupling of agriculture, forestry and animal husbandry forms a modern suburban agricultural system in the suburbs of Xifeng District, which integrates high efficiency, intensive, ecological, industrialization and science and technology.

【正文快照】： 城郊农业不仅承担着传统农业的生产功能,而且是保障城市生态可持续发展的生态安全屏障[1-2]。传统的城郊农业以高投入、高产出、高污染的发展模式,与农区的二元种植结构模式一样,过分强调其生产功能,大量使用化肥、农药和地膜,农作物的种植品种单一,造成土地退化,土壤肥力和涵
