摘要:耕地是粮食生产的物质基础,高标准农田建设是确保中国粮食安全的重要举措。以河北省卢龙县为研究区,分别从自然条件、工程条件与适宜经营条件3个方面,选取土壤质地等11个子目标,进行高标准农田建设适宜性评价;对于近期内被占用可能性较大,不适宜进行高标准农田建设的耕地,实行“一票否决”制,确定卢龙县高标准农田可建设区域,综合评价最终确定卢龙县高标准农田建设的时序。结果表明,卢龙县待建高标准农田面积共有39 280.84 hm2,分为3个时期,优先建设区、中期建设区和暂缓建设区,分别为9 557.87、18 644.33、11 078.64 hm2,各占卢龙县高标准农田建设总面积的24.33%、47.46%、28.21%。该研究可为卢龙县高标准农田建设规划提供科学依据。

Abstract:Arable land is the material basis of food production, high-standard farmland construction is important initiatives to ensure our food security. In this paper, the study area is Lulong County, there are three major aspects, the natural conditions, the project conditions and the suitable for the operating conditions and select the soil texture and the other 11 sub-goals to carry on the evaluation of the suitability of high-standard farmland construction; to determine the buildable area of high-standard farmland of Lulong County carry out the policy “One vote veto” for the arable land which is more likely to be occupied or it is unsuitable for the construction of high-standard farmland. Ultimately, comprehensive evaluation and determine the time sequence of the construction of high-standard farmland of Lulong County. The results showed that: the waiting area of Lulong County for the construction of high standard farmland is 39 280.84 hm2, divided into three periods:Priority Construction Zone, Mid-construction Zone and Suspend Construction Zone, the area are 9 557.87 hm2, 18 644.33 hm2 and 11 078.64 hm2, accounting for 24.33%, 47.46% and 28.21% of the total construction area of high standard farmland of Lulong County. The study provide a scientific basis for the building and planning of the construction of high standard farmland of Lulong County.

粮食安全问题是关系到中国国民经济和社会稳定的重大问题,伴随着城镇化快速发展和人民生活水平的逐渐提高,中国对于粮食的需求也呈刚性增长,尽管国家通过土地利用总体规划、划定基本农田保护区、试行耕地总量动态平衡等一系列措施保护耕地,但耕地的总体质量仍呈现下降趋势,耕地保护形势依然严峻。高标准农田作为耕地的精华,是确保中国粮食安全的关键部分[1]。综合国内众多学者对于耕地质量评价、基本农田定义以及农田改造的相关研究,可以将高标准农田定义为:土地平整,集中连片,耕作层深厚,土壤肥沃无明显障碍因素,田间灌排设施完善,灌排保障较高,路、林、电等配套,能够满足农作物高产栽培、节能节水、机械化作业等现代化生产要求,达到持续高产稳产、优质高效和安全环保的農田。……
