岷江彭山尖子山航电枢纽工程 下闸蓄水 将现“西湖级”湖面

Core Viewpoint - The successful completion of the reservoir filling at the Mijiang Pengshan Jianzi Mountain Navigation and Hydropower Hub marks a significant milestone for this key provincial transportation project, which is now entering the final stages before power generation [4]. Investment and Financial Summary - The total investment for the Mijiang Pengshan Jianzi Mountain Navigation and Hydropower Hub project is approximately 1.689 billion yuan [4]. - The expected annual power generation capacity of the project is around 285 million kilowatt-hours, with a total installed capacity of 69 megawatts [5]. Environmental and Safety Benefits - The reservoir filling process will raise the water level by 11 meters, reaching a normal water level of 426 meters above sea level, creating a lake area of about 6 square kilometers, comparable to West Lake in Hangzhou [5]. - The flood control standard for the reservoir area is designed to withstand a 1 in 50-year flood event, enhancing urban flood safety through improved water regulation capabilities [5]. Navigation and Logistics Impact - The hub will establish a four-level navigation channel capable of accommodating two 500-ton vessels simultaneously, significantly improving the navigation capacity of the Mijiang River [6]. - The project will facilitate the development of a multi-modal transport system in the Chengdu metropolitan area, linking water transport with rail and road networks, thus enhancing logistics efficiency [6]. Cost Reduction for Enterprises - Companies in Chengdu, Deyang, Mianyang, and Meishan will benefit from reduced logistics costs, as water transport is significantly cheaper than road and rail options, with costs being approximately 1/6 of road transport and 1/3 of rail transport [7]. Tourism Development - The newly formed lake will integrate with local tourist attractions, creating a "golden waterway tourism line" that connects various scenic spots, enhancing cultural and recreational opportunities [8]. - Future plans include the development of a passenger terminal cluster and the promotion of water sports, contributing to the integration of tourism and sports industries [8].
