中文摘要:一定规模的粮田对保障都市区粮食供应、营造城市景观等具有重大意义。以北京市平谷区为例,依据永久基本农田保护要求,首先提取允许建设区内的基本农田作为粮田优先划入区;其次,以耕地图斑为评价单元,从粮食生产能力、生态安全能力和区位条件3方面构建评价模型,对优先划入区外的耕地图斑进行定量评价;结合定量评价结果,最终确定平谷区粮田空间布局。结果表明:平谷区优先划入区的粮田面积为1427.26hm2,占区域耕地总面积的11.62%,主要分布在平谷县城与各镇中心周边;基于综合评价分值将优先划入区外的耕地划分为适宜划入区、储备划入区和不宜划入区3种类型,其中,适宜划入区主要分布在平谷县城东侧的地势平坦区域,并与优先划入区构成平谷区粮田的首选区域;储备划入区作为粮田储备可选区域,主要分布在县城的西部和南部乡镇;而不宜划入区空间分布零散,主要分布在地势较高、地形坡度较大的县城北部地区。由此形成的“生产-生态-区位”三位一体的都市区粮田布局方法可为北京生态涵养发展区的粮田布局提供科学依据。

Abstract:The quantity and spatial distribution of cereal field are important for food security and ecology function, especially in metropolitan area. A new method was presented to design the layout of cereal field in metropolitan area and these factors were accounted for in this method such as the land productivity, the ecological function as well as the geographical location. The first step was to identify the priority assigned region (PAR) and the none priority assigned region (NPAR) according to the properties and the locations of crop lands. If the crop lands were basic farmland and they also were within the region of allowable construction, these crop lands were identified as PAR and the others were identified as NPAR. The second step was to classify the NPAR into the suitable region (SR), the optional region (OR), the unsuitable region (UR) based on the comprehensive evaluation model(CEM). As a case study, this method was applied in Pinggu District in Beijing City to optimize the layout of cereal field. The results were as follow: the area of PAR was 1427.26hm2, accounting for 11.62% of the total cultivated area, and PAR distributed mainly around the urban area and neighboring towns. The area of NPAR was 10850.96hm2 The area of SR was 4450.75hm2, with the evaluation scores higher than 85.17. SR distributed mainly in the eastern region of Pinggu District. The area of OR was 3881.18hm2, with the evaluation scores between 8000 and 8517. OR distributed mainly in the western and southern regions of Pinggu District. The area of UR was 2519.03hm2, with the scores lower than 80.00. UR distributed mainly in the northern region of Pinggu District and the topography of UR is usually mountainous. The layout method of cereal field accounting for “Production-Ecology-Location” in this paper can provide a scientific basis for the grain layout in ecological conservation area of Beijing.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
