In winter, overlooking the Guangdong Hong Kong Macao Greater Bay Area from the sky, the Pearl River is vast, and Lingnan is lush with green onions. The the Pearl River traverses more than 2000 kilometers, forming a magnificent scene of "three rivers converging and eight ports entering the sea" in the the Pearl River Delta. The the Pearl River is long, with clear water connecting Hong Kong and Macao, benefiting people's livelihood; Sailing by boat, seeing clear waters and waves, white egrets fluttering; The industries on both sides of the Taiwan Strait are active, and the development of the "water economy" is showing initial results... A water management map of the Greater Bay Area, with rivers flowing smoothly and beautiful waters remaining evergreen, is slowly unfolding. In early December, walking into the Xinfengjiang Reservoir in Heyuan, Guangdong, a clear stream of water connects three places. The lake is green and the mountains are lush with greenery. The Xinfengjiang Reservoir is an important water source for the Dongshen Water Supply Project. 60 years ago, in order to solve the "water shortage" in Hong Kong, the Dongshen Water Supply Project started construction. Over 10000 builders, under difficult conditions, completed the 83 kilometer Dongshen Water Supply Project in just one year, solving the water shortage problem in Hong Kong. Currently, about 80% of Hong Kong's freshwater comes from Dongjiang, and about 1/4 of Dongjiang's water comes from the Xinfengjiang Reservoir Li Liang, Director of the Dongjiang River Basin Management Bureau in Guangdong Province, introduced that the current adjustable water volume of Xinfengjiang Reservoir is about 5.3 billion cubic meters. With the storage of Fengshuba Reservoir and Baipenzhu Reservoir, the total adjustable water volume of the three major reservoirs in Dongjiang is about 6.6 billion cubic meters, which can provide sufficient guarantee for water use in Hong Kong, Shenzhen, Dongguan, Huizhou, Guangzhou and other places this winter and next spring. In June this year, the the Pearl River Delta Water Resources Allocation Project, a major water conservancy infrastructure in the Guangdong Hong Kong Macao Greater Bay Area, officially supplied water, relieving the pressure of water supply in the Dongjiang River, and providing emergency standby water sources for Hong Kong in the future to further ensure the safety of water supply to Hong Kong. Macau has also faced the dilemma of water shortage. Since the 1950s, Macau's water consumption has been increasing, and the situation of self-sufficiency in water supply has gradually become unsustainable. A knowledgeable person has issued a request to the Guangdong Provincial Government, hoping to solve the water supply problem in Macau. In 1959, the Guangdong Provincial Government decided to build the Zhuxiandong Reservoir and Yinkeng Reservoir. In March 1960, the Zhuxiandong Reservoir with a total storage capacity of 2.4 million cubic meters was completed and put into use. In September of the same year, the Yinkeng Reservoir was also successfully put into use. Nowadays, the Dongshen Water Supply Project provides an annual water supply of 820 million cubic meters to Hong Kong and 100 million cubic meters to Macau, providing solid water resources support for the long-term prosperity and stability of Hong Kong and Macau. Mr. Liu, who has lived in Bao'an District, Shenzhen for many years, witnessed the transformation of the Maozhou River. Hu Haitao, Deputy Director of the Maozhou River Basin Management Center in Shenzhen, introduced that since 2016, the Maozhou River has built 2053 kilometers of sewage pipe networks in four years, completed the renovation of 2628 residential areas and urban villages, and added 810000 tons of daily sewage treatment capacity. In 2019, the stable elimination of black odor has made the 12.9-kilometer-long Maozhou River Blue Road a leisure and recreation place for citizens. Entering Jingxia Village, Huangpu District, Guangzhou, the river and lake are connected, and wild ducks are playing. There used to be over 100 independent mountain ponds here, and illegal fish ponds caused water pollution and prominent waterlogging hazards. By the end of 2023, about 120 natural water bodies will be connected locally, creating ecological environments such as bird paradise, wetlands, and forests, and creating a beautiful green belt from Pinggang River to Jingxia, completing the transformation of mountains and waters. Wang Baosen, Director of the Guangzhou Municipal Bureau of Ecology and Environment, said that the Knowledge City Jingxia Beautiful Unit is a demonstration project for Guangzhou to create a model of a beautiful Chinese city. Guangzhou attaches great importance to the construction of ecological civilization, deeply fights against pollution prevention and control, and steadily improves the quality of the ecological environment. In Guangzhou, along the banks of the Nangang River, there is a natural wilderness where children play together; In Jiangmen, the Xijiang River has clear water and green banks, and riverside cycling has become a new trend for young people... Zhang Weimin, a second level researcher at the River and Lake Chief of the Guangdong Provincial Department of Water Resources, introduced that Guangdong has upgraded and built a green and beautiful green belt that integrates the Anlan Healthy Water Belt, Green and Beautiful Landscape Forest Belt, Green Transportation Belt, Cultural and Leisure Belt, and Waterfront Economic Belt on the basis of the construction of green roads, promoting the improvement and upgrading of river and lake ecosystem governance. Data shows that Guangdong has built a total of 7111 kilometers of greenways, and has established national level happy rivers and lakes such as Nangang River in Guangzhou and Lianyang River in Shantou. Nowadays, in the cities of the Guangdong Hong Kong Macao Greater Bay Area, more and more rivers and lakes are turning from turbid to clear and from clear to beautiful. "Living by the water and resting by the water" is becoming a vivid portrayal of the beautiful life of the people in the Guangdong Hong Kong Macao Greater Bay Area. The 'water economy' inspires countless vitality. 'Left, right, left, right!' On summer weekends, a group of kayaking enthusiasts from Guangdong, Hong Kong, and Macao gathered on the Jiaomen River in Nansha District, Guangzhou. "The the Pearl River Delta is endowed with unique advantages in developing water sports due to its crisscross rivers and warm climate." Zhao Rongrong, president of Nansha District Sports Federation, introduced that the project of Nansha District Guangdong Hong Kong Macao Greater Bay Area Water Sports Base, located in Jiaomen River, was constructed in a franchising mode, and more than 300 new jobs were created by actively holding Loong Boat and kayak activities. Starting from water management, it's not just about water management. In recent years, Guangdong has promoted the healthy and orderly development of green water economy new formats such as water sports, water tourism, waterfront leisure and health care, and high-quality water use according to local conditions. On the land of Lingnan, stories of prosperity due to water continue to unfold: during the Chinese New Year, visitors flock to the Nanhai Water Flower Market in Foshan; In summer, the passion for water sports on yachts in Nansha, Guangzhou is surging; Entering autumn, strolling through the ancient waterfront villages of Shenzhen to explore historical and cultural heritage; At the beginning of winter, the fishing festival at Dashahe Reservoir in Jiangmen has driven villagers to achieve employment at their doorstep. Data shows that the cumulative investment completed in Guangdong's provincial-level water economy pilot projects is 3.66 billion yuan, of which social investment accounts for over 90%, and the projects have driven the creation of more than 1500 new job opportunities. Chen Ren, Deputy Director of the Water Resources Department of Guangdong Province, said that the water economy is connected to both industries and consumption, playing an important role in expanding effective investment, promoting household consumption, and increasing entrepreneurship and employment. The magnificent the Pearl River has nourished people in the hot land of Lingnan for thousands of years and witnessed the struggle of generations; And people also give back with the warmth of water, making the river greener and the two sides more beautiful, composing a harmonious chapter of water management in the Greater Bay Area.
