Abstract

Abstract:

The agricultural regional function is an important scientific problem in agricultural geography research, and it is also the important practical issue related to the national food security and sustainable development of regional agriculture. Taking the Bohai Rim region of China as an example, this paper identified the agricultural regional function as four types including agricultural products supplying function (APF), labor employment and social security function (LEF), ecological conservation function (ECF), and cultural heritage and recreational function (CRF) and their spatial pattern and evolution process were explored. The study also identified the agricultural regional type and the impact factors affecting the four functions using cluster analysis method and spatial econometric model. The results indicate that: Firstly, the degrees of spatial concentration of the APF, LEF and CRF were low, while that of the ECF was high. The spatial distributions of the four functions presented obvious regularity. Secondly, the APF enhanced largely, its center of gravity was further concentrated in plain agricultural areas. The high value areas of the LEF shifted from inland to coastal areas. The ECF of hilly areas further highlighted. Advantage areas of the CRF were concentrating in the municipal districts and their surrounding counties. Thirdly, the leading counties of the APF were distributed in central and southern plains of Hebei province, the impact plain of northwest Shandong, the Jiaolai plain and the west of Liaohe plain. The leading counties of LEF were distributed in piedmont plain of Yanshan and coastal plain of Hebei province, Jiaodong Peninsula and the Yellow River Delta region. The leading counties of the ECF were distributed in Bashang plateau, mountainous region of Yanshan, hilly area of eastern and western Liaoning province, and the surrounding areas of Beijing-Tianjin-Hebei urban agglomeration. The leading counties of the CRF were distributed in the surrounding areas of central-south Liaoning urban agglomerations, Beijing-Tianjin-Hebei metropolitan region and Jinan metropolitan area. Comprehensive counties were distributed in the Huang-Huai plain and hilly areas of central-south of Shandong province. Fourthly, natural factors possessed a significant impact on the formation of the three functions including APF, LEF and ECF, while social and economic factors on the impact of the four functions were quite different. The study reveals the regularity and influence mechanism of the evolution of agricultural regional function, which can provide theoretical basis for scientific guidance of regional division of labor, strengthening of leading function, highlighting regional value and promoting regional coordinated development.

Basic features and development orientation of 13 kinds of county functional types in the Bohai Rim region

主导功能	功能类型	县域数量	人均粮食产量(kg)	人均 GDP(元)	农民人均纯收入(元)	城镇化率(%)	基本特征	发展导向
APF	生产— 生活型	37	639	34700	9250	53.0	该类型区多为传统粮棉生产基地,农业生产受水资源匮乏和土壤盐碱的限制;地区工业化、城镇化迟缓,社会保障功能弱,农民人均纯收入普遍处于低水平。	未来应围绕国家粮食战略工程重点区域开发,提升农业生产规模与产业化水平,建设高质量农产品种植基地、技术研发基地、农产品深加工基地、现期货交易和商品流通平台,不断提升农产品供给能力与农业内部增产潜能。
	生产— 生态型	25	722	37214	9365	51.2
	生产— 休闲型	49	734	24713	8965	56.6
LEF	生活— 生产型	18	332	59184	9690	67.4	该类型区多为沿海地区,特色农产品供给优势明显,经济发展水平较高,就业和社会保障功能强,但水资源匮乏,盐渍化严重,生态环境脆弱。	未来应紧紧围绕农业供给侧结构性改革主线,推进农产品品种和结构的调整创新,强化农业高新技术培育、示范带动、服务辐射等服务功能,进一步提升沿海地域农业就业保障能力与生态屏障功能。
	生活— 生态型	23	481	62759	11007	63.1
	生活— 休闲型	24	173	94282	12543	55.0
ECF	生态— 生产型	21	528	44745	9278	62.6	该类型区地势起伏大,森林蓄积量较大;耕地质量差,农业生产水平落后;人口密度较小,二三产业欠发达,保障生活的功能弱。	未来要以生态文明建设为契机,加快实施重大生态工程和农业生态保护修复工程,合理构建生态补偿机制;立足贫困山区资源禀赋,构建支撑农业绿色发展的科技创新体系,推进特色产业精准扶贫,引导贫困农户脱贫致富。
	生态— 生活型	30	466	51826	9340	53.7
	生态— 休闲型	27	171	90335	12633	60.9
CRF	休闲— 生产型	15	341	62393	11670	69.1	该类型区凭借特色资源和优越区位条件,农业休闲旅游业蓬勃发展,但空间布局杂乱无序,开发项目单一且缺乏特色,基础设施落后且服务水平低。	未来需结合该区物质与文化资源集聚的特有优势,引导农林业与文化、教育、疗养、观光等新业态深入融合,促进农村休闲观光业态多元化、产业规模化、主体多样化、设备现代化和服务专业化,使之成为兴村富民的新型支柱产业。
	休闲— 生活型	25	493	130657	12310	59.2
	休闲— 生态型	15	212	60167	12070	67.7
综合型	4项功能值均偏低	18	536	20180	8368	32.2	鲁中南地区农业生态调节功能较弱,水土流失多发,土壤肥力低下;鲁西南平原是传统粮棉主产区,产业发展水平低,经济建设基础薄弱。	未来鲁中南地区需因地制宜发展特色高效农业,并构建水土流失综合治理与防护体系;鲁西南粮棉种植应向优质、专用、特供方向发展,培育粮食深加工与物流,推进农产品在产业循环链条中互补增值,带动农民就业增收和精准脱贫。
