摘　　要：在对夏津县风沙化土地基本特征进行研究和生产力评价的基础上，与地方政府结合，规划建立了“苏留庄粮棉果草复合型稳产高产开发模式”。在风沙化土地治理研究的同时，及时将优良作物品种和树种推广到示范区，并采用沙地土壤改良、立体种植和绿肥轮作等先进有效的耕作技术。现在，示范区已成为一个集农、林、牧为一体的综合开发体系，取得了显著的社会、生态和经济效益，示范区第３年的农业总产值已达４０１．４３万元，相当于建设投资的总和。in this paper, some experimental results in Xinjing were introduced briefly. Based on research of properties and appraisal of productivity of blownsand soil in Xiajing county, in cooperation with local government, the model of high-yield and stable-yield that plant grain, cotton, fruit-tree and grass has been established in Suliuzhuang. Some improved varieties of crop and fruit-tree and advanced tillage technology such as sandy soil improvement,stereoscopic cultivation and green manure shift agriculture were extended in the representative area. So far, the representative area has become a comprehensive development system of agriculture and forestry and livestock raising. Remarkablesocial, ecologiCal and economic benefits have been made. In third year, the total output value of agriculture and forestry of the representative area was 4. 014 3 million yuan, roughly equalling to the total investment.
