Core Viewpoint - The article emphasizes that China's hydropower development is not only focused on electricity generation but also on ecological preservation, showcasing innovative designs that enhance fish migration and maintain ecological balance [1] Group 1: Hydropower Stations - The Wudongde Hydropower Station, as the fourth largest in China and seventh in the world, has implemented a tailwater fish collection system that has successfully created a "highway" for fish migration, with over 60 species transported to date [1] - The Jinsha Hydropower Station features a fishway known as the "first fishway of the Yangtze River," designed based on in-depth research of fish migration habits, creating a 1486-meter ecological passage that has facilitated the passage of 420,000 fish since 2021 [1] - The Yinjing Hydropower Station integrates ecological concepts into urban areas, featuring a 1003-meter fishway designed to simulate natural river environments, effectively addressing a 18-meter drop challenge and achieving a harmonious blend of engineering and ecology [1]

Core Viewpoint - Dongguan's Changping, once a leading economic town, faces challenges in reclaiming its status amid rising competition and the need for transformation into an "ecological hub" from a "transportation hub" [1][6]. Group 1: Economic and Transportation Challenges - Changping was the top economic town in Dongguan in 1995, but now ranks seventh as other areas like Songshan Lake and Chang'an join the GDP trillion club [1]. - The emergence of high-speed rail connections within the Greater Bay Area has diminished Changping's transportation advantages, with nearby stations like Humen and Dongguan South becoming regional hubs [1][2]. - Daily passenger flow at Humen station exceeds 30,000 during holidays, highlighting the competitive pressure on Changping's railway hub [1]. Group 2: Strategic Development Initiatives - Changping's local government is advocating for the transformation of Changping and Dongguan East stations into high-speed rail starting points, which could enhance regional development and attract more resources [2]. - The TOD (Transit-Oriented Development) project at Changping station, named "Hong Kong City," has been initiated, aiming to convert transit traffic into local economic activity [2][4]. - A shift from traditional manufacturing to high-tech industries is necessary for Changping, focusing on integrating with sectors like electronic information and logistics [4]. Group 3: Urban and Industrial Transformation - Changping must evolve from a "manufacturing stronghold" to a "smart manufacturing node," emphasizing the need for innovation and brand development in traditional industries [4]. - The TOD development should not only focus on physical upgrades but also on creating a vibrant commercial ecosystem that mirrors Hong Kong's trade dynamics [4][6]. - The overall strategy involves redefining Changping's identity within the Greater Bay Area, transitioning from a transportation hub to a new ecological node [6].
