摘要
黄河三角洲是全球最年轻的三角洲和新生陆地之一,也是最年轻的湿地生态系统,生态环境脆弱,河-海-陆交互形成了独特的地理环境。土地盐渍化、盐碱地数量大、分布广是该地区的主要特征之一。农业开发不仅涉及该地区的水资源高效利用和合理分配、河口湿地的保护和整个区域的生态环境友好、土地资源的高效开发和安全、陆-海统筹发展,还关乎该地区的乡村振兴。因此,盐碱地农业高质量发展成为该地区可持续发展的重要环节,在盐碱地上发展高质量农业面临重要挑战。文章依据国家重大战略需求、黄河三角洲发展现状及主要问题,提出了应用生态系统工程技术支撑黄河三角洲盐碱地高效农业发展的新模式,并给出该地区未来生态保护和高质量发展的建议。该研究对于我国盐碱地的高效开发也具有重要意义。
The Yellow River Delta is the world’s youngest delta and new land, also the youngest ecosystem. Its ecological environment is fragile, and the interaction among the river, the sea, and the land forms a unique geographical environment. The salinization of land and the wide distribution of saline land are two of the main features of the region, and agriculture is one of the leading industries in the region. Agricultural development is related to the efficient use and rational distribution of water resources in this area, related to the protection of the estuary wetland and the ecological environment of the whole region, and related to the efficient development and safety of land resources. It is also about the overall development of land and sea, as well as about the revitalization of the countryside. Therefore, the high quality development of saline agriculture is the important part of sustainable development of the region, while the development of high-quality agriculture in saline land is an important challenge. Based on the major strategic needs of the country, the current situation, and major problems of the development of the Yellow River Delta, this study puts forward a new model of efficient agricultural development in the saline-alkali areas of the Yellow River Delta, as well as some suggestions for the future ecological protection and high-quality development of the region. This study is also of great significance for the efficient development of saline land in China.
