昌黎县中部有沙地资源29万亩，土地瘠薄，生态环境恶劣，生产能力低下。昌黎县从1988年开始对沙地进行以打井、配电、修路、发展农田防护林网等为主要内容的规模立项开发。经过多年的实践，使沙地生产面貌得到较大改善。在沙地得到初步改造治理后，为促使沙地向高标准、高效益、园田化发展，经过多年探索，昌黎县摸索出了沙地保护地蔬菜生产，栽植乔木保护沙地果园，沙地节水高效种植，沙地防风林生态建设，和畜禽养殖，农副产品加工等五种高效利用模式，并在县内大力推广，取得了较大的综合效益，为沙地资源的深度开发利用探索了路子。

Starting from 1988, Changli County started to project the project of digging wells, power distribution, road repair and development of farmland shelterbelts as its main content. After years of practice, the production of sand land has been greatly improved. In order to promote the development of sandy land to a high standard and high efficiency and to facilitate the development of the parkland, after many years of exploration in Changli County, Changli County has worked out vegetable production in the protected areas of sandy land, planted arboriculture to protect sandy orchards, Efficient planting of water, ecological construction of sandy land, and livestock and poultry breeding, agricultural and sideline products processing and other five kinds of efficient use of model, and vigorously promote in the county, and achieved greater comprehensive benefits for the exploration and utilization of sand resources in depth Way.
