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。
Urban agriculture undertakes a dual function of ecological conservation and economic development in arid regions in Western China.Traditional urban agriculture has not been able to adapt to the demands of urban- rural integration,which have changed from a single production function to the multiple functions in production, ecology, landscape, and culture. Here, we design couple models based on functional coupling, industry cou- pling, and spatial coupling of urban agriculture in Xifeng District of Qingyang City in Gansu Province, accord- ing to natural resource features, development status, functional orientation, and spatial layout of agriculture. These models assess efficient vegetation restoration and ecological conservation, high-quality productive agri- culture and livestock, and leisure and cultural development. The modern urban agriculture system is based on soil and water conservation and ecological conservation, development-oriented of efficient high quality produc- tion,various means of agriculture, and forestry and animal husbandry through 3 modes of integrated application in the Xifeng District of Qingyang City in Gansu Province.
