China News Service, Guangzhou, October 29 (Reporter Wang Jian) According to the Pearl River Water Conservancy Commission of the Ministry of Water Resources (hereinafter referred to as the "Pearl River Commission") on the 29th, in order to implement the water distribution plan and dispatch plan in the Xijiang Basin and strengthen the unified dispatch of water resources in the Xijiang Basin, the Pearl River Commission organized the preparation of the "2026-2027 Xijiang Basin Water Resources Dispatch Plan" (referred to as the "Annual Plan"). The "Annual Plan" was recently approved and issued by the Ministry of Water Resources, marking the official launch of the unified water resource dispatching in the Xijiang Basin in 2026-2027.
According to the Pearl River Committee, the dispatch scope of the Xijiang River Basin covers the main stream of the Xijiang River and nine major tributaries such as the Beipanjiang River and the Liujiang River. The basin area is about 350,000 square kilometers, and the multi-year average total water resource volume is 230 billion cubic meters.
The "Annual Plan" scientifically determines the annual water distribution indicators for the five provinces (autonomous regions) of Yunnan, Guizhou, Guangxi, Guangdong, and Hunan on the basis of coordinating the water needs of all parties such as life, production, and ecology, and clarifies the discharge flow (water volume) indicators of 30 control sections including Wuzhou. According to the standard, the dispatching plan for the main dispatching projects of 35 trunks and tributaries, including Longtan and Dadengxia, is clarified, and the requirements for division of dispatching responsibilities, forecasting and early warning, information submission and sharing, supervision and management are provided to provide rigid basis and technical support for the annual unified dispatching of water resources in the Xijiang River Basin.
The "Annual Plan" requires that relevant provinces (autonomous regions) should consolidate all levels of dispatch management responsibilities, organize the implementation of water resource dispatch within their jurisdiction, strictly implement the "Annual Plan" and dispatch instructions, strengthen daily supervision and management, and implement water distribution indicators and ecological flow target requirements; Longtan, Dateng Gorge, Baise Reservoir and other water resources Project management units should incorporate ecological flow dispatch into daily operation dispatch procedures, implement dispatch in strict accordance with the requirements of the "Annual Plan" and dispatch instructions, implement main control sections and project discharge flow target requirements, reasonably arrange production plans such as water supply, power generation, and shipping, and monitor and submit dispatch information.
The Pearl River Commission stated that since October, the water supply at Wuzhou Station of the Xijiang River has been 30% less than the annual average, and the water supply from major tributaries such as the Huangni River, Beipan River, and Yujiang River has been 50 to 60% less than the average. It is predicted that the water supply will continue to be dry during the dry season, and the water supply security situation in the basin is grim. In the next step, the committee will strengthen the organization, coordination, supervision and guidance of water resources dispatch in the Xijiang River Basin, strengthen the management of the dispatch process, combine the incoming water from the basin, reservoir water storage and changes in water demand, strengthen the rolling forecast of the dry season, dynamically optimize the dispatch plan, and issue dynamic dispatch instructions in a timely manner to ensure the safety of water supply and ecological security in the basin.
