3月16日，游客在重慶廣陽島油菜花田游覽（無人機照片）。春日時節，重慶廣陽島春意盎然，一片生機勃勃的景象。廣陽島是長江上游最大的江心島。近年來，當地積極探索基于自然的解決方案，創新運用“護山、理水、營林、疏田、清湖、豐草”六大策略，系統推進自然恢復、生態修復，豐富生物多樣性。同時，融合高品質生態設施和綠色建筑，建成上壩森林、高峰梯田、油菜花田、勝利草場、東島頭等24個生態修復示范地。歷經生態蝶變的廣陽島，呈現出一幅原生態的巴渝鄉村田園風景畫卷，成為生動表達山水林田湖草生命共同體理念的“生態大課堂”，吸引市民和游客前來感受大自然之美。[新華社記者王全超攝]

Guangyang Isle, the most extensive green island in the upper reaches of the Yangtze River, has been turned into an ecological restoration and protection "classroom" for ecotourists and school children. The local ecosystem and biodiversity were once seriously threatened due to real-estate projects in the area. However, the local government brought harmful projects of this sort to a halt in 2017, starting the restoration of the environment on the island. (Xinhua/Wang Quanchao)
