"渔光互补"模式则让水资源利用更具智慧。利津县100兆瓦项目将光伏板架设在养殖池塘上方，板上发 电、板下养鱼，实现"一水两用、一塘双收"。该项目年发电量达1.2亿千瓦时，相当于节约标准煤3.6万 吨，同时池塘亩产鱼虾提升至1200斤，较传统养殖增收30%。这种"水上清洁能源、水下生态养殖"的立 体开发，彻底改变了"盐碱地只能撂荒"的旧认知。 经济效益与生态安全的动态平衡 光伏电站的建设，为东营带来了实实在在的"绿色收益"。截至2025年6月，全市盐碱地光伏项目累计投 资超80亿元，带动就业岗位5000余个，其中90%为本地农民。在垦利区，村民通过土地流转获得每亩每 年800元租金，还可参与板下作物种植、电站运维等工作，人均年收入增加2.4万元。正如黄河口镇盐窝 村村民王建军所说："以前种地靠天吃饭，现在土地租出去有租金，干活还有工资，日子踏实多了。" 当黄河三角洲的盐碱地上架起成片光伏板，板上蓝色电池板追光发电，板下耐盐作物茁壮成长，东营正 以"光伏+生态"的创新实践，破解生态脆弱区"保护难、开发更难"的发展悖论。 作为全国盐碱地最集中的地区之一，东营将20万亩盐碱地转化为新能源基地，"板上发电、板下种植"模 ...

新华社乌鲁木齐8月25日电（记者苟立锋）25日，中国－中亚盐碱地科技创新与合作国际学术交流会在 新疆举行。来自中国、哈萨克斯坦、乌兹别克斯坦、塔吉克斯坦等国家的科研院所、高校、企事业单位 专家和代表近200人齐聚新疆昌吉市，围绕盐碱地治理和农业可持续发展领域的科技创新与合作等议题 展开学术交流。 据了解，我国盐碱地面积约5亿亩，其中新疆盐碱地面积占全国盐渍化土壤总面积的36.8%，改造开发 潜力巨大。而新疆与中亚国家地理相邻、生态相似，在盐碱地改良、耐盐作物育种等领域拥有广阔的合 作空间。 "我们始终坚持把盐碱地治理与可持续利用作为科技援疆和对外合作的重点方向之一。"中国农业科学院 副院长、党组成员孙坦表示，中国农业科学院未来将立足昌吉，辐射全疆和中亚，聚焦盐碱地改良、生 物育种、智能灌溉等关键技术，开展一系列前沿研究和集成示范。 会议期间，中国农业科学院西部农业研究中心分别与乌兹别克斯坦土壤科学与农业化学研究所、哈萨克 斯坦土壤科学与农业化学研究所签署谅解备忘录，中外科学家将在盐碱地治理、畜牧养殖、食品安全和 国际教育等领域开展深度合作。"希望我们未来能互通有无，能让我们的技术造福我们的生活，以更低 的治理 ...
