In the 1950 s, due to flooding in Guangzhou, the mayor personally took the lead in picking mud. A nationwide lake building movement also dug Liuhua Lake, Liwan Lake, Luhu Lake and Dongshan Lake. Baiyun Lake and Haizhu Lake, which were built by the Asian Games for water control, are inspired. They not only improve the environment and enhance the image and taste of the city, but also bring soaring land value. Therefore, various districts are scrambling to build artificial lakes, and one is bigger than the other. According to the relevant plan, Guangzhou will also build eight artificial lakes, namely Huadu Lake, Yunling Lake, Jinshan Lake, Tianhe Wisdom City Lake, Zengcheng Gualu Lake, the artificial lake in the starting area of Sino-Singapore Knowledge City (officially named Phoenix Lake at the end of last month), Jiulong Sea and Longtou Lake in Huangpu District. According to public media reports, Luogang Jiulong Sea costs 6 billion yuan (currently reduced, details are unknown), Panyu Jinshan Lake costs more than 0.4 billion yuan, Huadu Lake is expected to invest 0.57 billion yuan, Tianhe Wisdom City Lake 0.5 billion yuan, Zhongxin Knowledge City Starting Area artificial lake 0.398 billion yuan, Zengcheng Luhu 9.409 billion yuan. Add 0.678 billion yuan of Shanghai Pearl Lake, Baiyun Lake invested about 1.268 billion yuan, and the greening project also cost 84 million yuan. The total cost of the eight artificial lakes that can be found above is 19.307 billion yuan (Huangpu Longtou Lake and Conghua Yunling Lake have not found a clear total investment). What is the concept of 19.307 billion yuan? The subway line 3, which runs through Guangzhou city from north to south, is 36.86 kilometers long and has 18 stations, with a total investment of 15.905 billion yuan. Lake building seems to be a huge investment, in fact, almost every new artificial lake is accompanied by the planning and construction of a new city. Around Baiyun Lake has been planned 38 square kilometers of Baiyun Lake New City, Liuxi River and Conghua Lake also accompanied by a 50 square kilometers of Conghua New City, Zengcheng hanging green lake around the new city area of 110 square kilometers, Huadu Lake is located in the planning of Huadu axis ...... Zengcheng Municipal Party Secretary Cao Jianliao once said, hanging green lake scenic area built, the surrounding a line of lake scenery prices will reach 30000-50000 yuan/square meters, tan Junle, secretary of the party committee of Jiulong Town, Luogang District, once said that after the construction of Jiulong Sea, housing prices on both sides of the strait are expected to reach 15000-20000 yuan per square meter. From the public speeches of these officials, it can be seen that local officials hope to bring property prices to a new level by building lakes.
