摘 要:在当前"渤海粮仓"工程进入关键实施期的背景下,评价盐碱地改良利用效益,对于推进"渤海粮仓"建设具有重要的现实意义。该研究采用面上调查和典型抽样调查相结合的方式,对"渤海粮仓"山东项目区典型示范区参与项目的不同农业经营主体、土地利用(经营)模式进行生产成本收益典型抽样调查。结果表明,土地利用复合模式、优质品牌农产品收益较高,科技投入、产业链完整性对收益影响较大,盐碱地改良利用具有长期效益;但盐碱地改良初期投入成本较高、农田水利条件限制、农业产业链和现代农业组织型式不完善是限制"渤海粮仓"山东项目区发展的重要因素。针对存在问题提出了相关建议,为政府采取措施加快推进"渤海粮仓"建设和企业、农户采取措施提高经济效益提供参考。As the implementation of "Bohai granary" project has entered a critical period, evaluating the benefits of improvement and utilization of saline and alkali land, has important practical significance for promoting the "Bohai granary" construction. Using methods of general survey and typical sample survey, different subjects of agribusiness and land use (business) modes in the typical demonstration area of "Bohai granary" Shandong project were surveyed. The results indicated that the complex pattern of laud use and premium brands agricultural products gained higher yields, science and technological investment and integrity of industrial chain had greater influence on yields, and the improvement and utiliza- tion of saline and alkali land had long-term benefit. The results also indicated that, the higher initial cost of improvement and utilization of saline and alkali land, the restrict of farmland water conservancy conditions, and the imperfection of agricultural industry chains and modern agricultural structure, are the important factors limiting the development of "Bohai granary" project in Shandong Province. Aiming at the existing problems, relevant proposals were put forward. The results can help government to take measures to accelerate "Bohai granary" construction, and help enterprises, farmers to take measures to improve economic benefit.
