城市郊区耕地入选基本菜田的综合质量评价
Comprehensive quality evaluation on arable land allocated for basic vegetable production in metropolitan suburb
摘要
Abstract
Designation of basic vegetable land aims to improve production capacity and ensure a balanced supply of vegetables in urban areas. This research built a comprehensive evaluation model of arable land selected for basic vegetable production in the Pinggu District of Beijing in order to provide a scientific basis for allocating basic vegetable land in metropolitan suburb. The results showed that: 1) the primary needs of arable land quality for vegetable production and the policy requirement of the state and the Ministry of Agriculture for basic vegetable production were the fully considered in the comprehensive quality evaluation of arable land allocated. This focused on four aspects: land quality, ecological adaptability, space stability, road accessibility and planting habit, including the supply and need of water resource, main water source protection zone and other indexes; 2) based on the results of the above evaluation, the possible areas of arable land in Pinggu District were divided into the most suitable areas (>82), suitable areas (>75-82), sub-suitable areas (>67-75) and unsuitable areas (≤67). Among which the most suitable area was the initial choice for basic vegetable production, an area of 3 472.33 hm2, which was mainly located in Donggaocun Town, Xiagezhuang Town, Shandongzhuang Town and Daxingzhuang Town around the Pinggu new town. Suitable area and sub-suitable areas were potential reserve areas for basic vegetable production. 3) It is suggested that by focusing on the construction of a"Non-Staple Food Project" in Beijing, the hierarchical construction and protection of basic vegetable land should be enhanced to form a vegetable production pattern with outdoor vegetable, facility vegetable and vegetable park mutually complementing with each other.关键词
