据了解，引大济岷工程以大渡河泸定水电站库区为起点，蜿蜒穿越至成都平原，构建起"一总两干"的输 水格局——总干线133千米，南干线103千米，北干线25千米，工程输水线路总长261千米，其中隧洞占 比超58%，堪称"地下输水长城"。工程设计年引水量15.23亿立方米，取水口设计引水流量80立方米/ 秒，覆盖成都、德阳、绵阳等8市43县(市、区)，受益人口3413万人，供水范围与成都平原经济区高度 契合。 引大济岷工程建成后，将与都江堰供水工程形成双水源水网体系，结束成都平原"单水源依赖"历史，新 增灌溉面积179万亩、改善灌溉面积591万亩，为"天府粮仓"筑牢灌溉保障网。工程连通大渡河、青衣 江、岷江、沱江、涪江，推动成渝地区生态廊道建设，提升区域水资源调蓄能力，助力长江上游生态屏 障建设。同时，将有效改变成都、德阳等地水资源短缺的发展瓶颈，为电子信息、装备制造等支柱产业 提供稳定水源。 本报雅安11月10日电(记者李凯旋)日前，引大济岷工程建设动员大会在四川省雅安市天全县召开，标志 着这项四川水利史上投资最大、线路最长、受益最广的跨流域引调水工程正式进入建设阶段。 ...

Core Points - The construction of the Wuhan 100-mile Yangtze River Ecological Corridor has been largely completed after five years, connecting the riverbanks within the city's third ring road [1][2] - The completion of the Jianghan Greenway project and the Wuchang Bay flood control and environmental improvement project marks the removal of the last two "breakpoints" along the Yangtze and Han rivers, providing citizens with over 80 kilometers of continuous riverside access [2][4] Group 1 - The ecological corridor aims to enhance flood safety and urban aesthetics, with the first phase of the Hankou riverbank construction starting in February 2002 [2][5] - The project includes 16 sub-projects designed to address issues of disconnected riverbanks and insufficient landmark scenery and service facilities [5] - The transformation of abandoned cargo docks into recreational areas and the integration of historical cultural elements into the landscape are part of the ongoing development [5] Group 2 - Future planning and construction will focus on enhancing the connectivity between the riverbanks and the city, aiming for a harmonious integration of water, banks, beaches, cities, and people [5]

Group 1 - The core focus is on the conservation and habitat restoration efforts for the Sichuan Hill Partridge, a critically endangered species endemic to southwestern China, particularly in Sichuan [6][7] - The Sichuan Hill Partridge population is currently estimated at around 2,200 individuals, with habitat area exceeding 6,000 square kilometers, showing significant growth compared to previous surveys [7] - The restoration project involves planting native species such as August bamboo and other local tree species over an area of 600 acres, specifically designed to enhance the habitat for the Sichuan Hill Partridge [5][8] Group 2 - The project aims to address the bottleneck in the species' distribution, as the Sichuan Hill Partridge primarily inhabits specific mountain forests between 800 and 2,500 meters in elevation, where August bamboo is crucial for its breeding [6][8] - The restoration efforts include selective logging of non-native species and planting of local flora to improve habitat quality, thereby providing food and shelter for the partridge [8][9] - Future plans include expanding the habitat restoration to adjacent areas, potentially increasing suitable habitat to 400 square kilometers and facilitating genetic exchange among partridge populations [9]

Core Viewpoint - The population of Sichuan golden monkeys in the Qinling Mountains has reached a new peak in newborns this year, indicating a stable growth trend in their population [1][5]. Group 1: Population Growth and Monitoring - The research team from Northwest University has established two observation stations with 20 observation points to monitor the Sichuan golden monkey population [5]. - The latest statistics show that the population of a single group of Sichuan golden monkeys in the Zhouzhi National Nature Reserve has exceeded 340 individuals, making it the largest known group in the Qinling region and nationwide [5]. Group 2: Ecological Corridor and Biodiversity - The "monkey road" in the Qinling core area has become a migration corridor for wildlife, originally built for logging but now facilitating genetic exchange among various species [5][9]. - The Zhouzhi National Nature Reserve was established primarily for the protection of the Sichuan golden monkey and is a key area for ecological corridor construction [7]. - The ecological corridor has not only benefited the golden monkey population but has also attracted other rare species, such as giant pandas and leopards, enhancing biodiversity in the region [9][11]. Group 3: Human-Wildlife Harmony - The ecological corridor represents a significant project for ecological protection, showcasing a vision of harmonious coexistence between humans and wildlife [11].

Core Points - The renovation of the Xiatang River ecological corridor has transformed it into a vibrant recreational area, featuring clear water, green banks, beautiful scenery, and a joyful atmosphere for residents [2][3] - Over 200 new trees, including cherry blossoms, peach trees, and crabapple trees, have been planted along the river, enhancing the aesthetic appeal and creating a picturesque environment [2] - The upgraded 4.5-kilometer permeable asphalt walkway provides an excellent path for walking and jogging, with features like embedded glow stones and a rainwater drainage system [2] - Seven "water-friendly points" have been established along a 200-meter section of the corridor, offering picnic spots and children's play areas that incorporate traditional cultural elements [3] - The overall goal of the renovation is to reconnect the river with the community, creating a "big garden" for residents to enjoy [3]
