【摘要】：合理划定基本菜田是提升蔬菜生产能力、保障城市蔬菜均衡供应的基础。该研究在界定基本菜田内涵的基础上,构建平谷区耕地入选基本菜田的综合质量评价模型,以期为大城市郊区基本菜田布局提供科学依据。结果表明:1)从田块质量、生态适宜性、空间稳定性、交通区位与蔬菜种植习惯等4方面构建耕地入选基本菜田的综合质量评价指标体系,充分考虑了蔬菜生产对耕地质量的基本需求以及国家和农业部对基本菜田的政策要求,包含了水资源供需状况和重要水源保护区等指标,使得该研究的评价方法更合理;2)平谷区耕地的田块质量、生态适宜性、空间稳定性、交通区位与蔬菜种植习惯等评价结果呈现差异性分布。基于综合质量评价结果,将平谷区耕地图斑划分为最适宜区、较适宜区、一般适宜区和不适宜区。其中,最适宜区是基本菜田的首选区域,主要分布在平谷新城周边的东高村镇、夏各庄镇、山东庄镇和大兴庄镇,面积为3 472.33 hm2,占平谷区耕地总面积的28.25%;其次是较适宜区,面积为5 186.28 hm2;一般适宜区的面积为2 860.86 hm2,可作为基本菜田储备区域;不适宜区的土壤表土质地差、有机质含量低,加之远离平谷新城、交通不便等因素,不适宜划为基本菜田。3)建议围绕首都"菜篮子工程"建设,强化基本菜田的分级建设与保护,形成露地蔬菜、设施蔬菜和蔬菜园区相互补充的蔬菜生产格局。
[Abstract]:The rational delineation of basic vegetable fields is the basis of improving vegetable production capacity and ensuring balanced supply of urban vegetables. On the basis of defining the connotation of basic vegetable fields, a comprehensive quality evaluation model for the selection of cultivated land into basic vegetable fields in Pinggu area is constructed. In order to provide scientific basis for the layout of basic vegetable fields in the suburbs of big cities, the results show that the field quality, ecological suitability and spatial stability are determined by the analysis of the field mass, ecological suitability and spatial stability. The comprehensive quality evaluation index system of cultivated land selected to basic vegetable fields is constructed in four aspects, such as transportation location and vegetable planting habits. The basic demand of vegetable production for cultivated land quality and the policy requirements of the state and the Ministry of Agriculture on basic vegetable fields are fully considered. Including the water resources supply and demand situation and the important water source protection area and so on, which makes the evaluation method of this study more reasonable (2) the farmland quality, ecological suitability and spatial stability of the cultivated land in Pinggu area. Based on the results of comprehensive quality evaluation, the cultivated land spots in the flat valley area are divided into the most suitable area, the more suitable area, the general suitable area and the unsuitable area. The most suitable area is the first choice for basic vegetable fields, mainly distributed in Donggaocun, Xiagezhuang, Shandong and Daxingzhuang towns around Pinggu New City, with an area of 3 472.33 hm2, accounting for 28.25% of the total cultivated land area in Pinggu, followed by the more suitable area. The area is 5 186.28 hm2, the area of general suitable area is 2 860.86 hm2, which can be used as the basic vegetable field reserve area, the soil surface soil texture is poor, the content of organic matter is low in the unsuitable area, in addition, it is far away from Pinggu New Town, and the transportation is inconvenient, etc. It is not suitable to be classified as basic vegetable field. (3) it is suggested that the construction of "vegetable basket project" should be centered around the construction of the capital's "vegetable basket project", and the construction and protection of basic vegetable fields should be strengthened, so as to form a vegetable production pattern in which vegetables in open fields, facilities and vegetable parks complement each other.
