Foreign cases of protecting traditional villages

1. The water control model of silver carp and bighead carp in Qiandao Lake can be said to be an excellent example of paying equal attention to environmental protection and economic development. Developing aquaculture while managing water bodies and optimizing water quality while developing aquaculture complement each other.

2. Qiandao Lake is a national first-class water body, and one of the water intake places of Nongfu Spring is Qiandao Lake. These fish raised in Nongfu Spring are real organic fish, and they are delicious. Often, the first net100000 Jin in spring will be plundered, and it can't be bought if it is slow. Therefore, the fish and water in Qiandao Lake have attracted much attention. However, Qiandao Lake is not always so clean. 1998 Qiandao Lake was seriously polluted, and the catch in that year was three quarters less than that in the previous year, which can be said to be a cliff-like decline. At that time, the problem was the eutrophication of water bodies, which made cyanobacteria multiply in large numbers and formed water blooms. The water bloom covered the surface of the water, making it difficult for almost all living things in the water to survive. The resources in the water body have been greatly reduced, and the production and life of local people have been affected. In order to restore local fisheries, the Environmental Protection Bureau has carried out a series of actions. Finally, the experience of East Lake and Dianchi Lake was used for reference, and silver carp and bighead carp were used to treat cyanobacteria. These two kinds of fish feed on phytoplankton and zooplankton respectively, which greatly improves the water bloom problem in Qiandao Lake.

3. Over the years, great achievements have been made in the water management of Qiandao Lake. Silver carp and bighead carp are organically stocked in the waters and feed on algae and zooplankton, which not only purifies the waters of Qiandao Lake, but also develops the aquaculture of silver carp and bighead carp, killing two birds with one stone. Today, Qiandao Lake is already one of the water intake places of Nongfu Spring. When the flood is discharged, the water is clear, which shows that its water quality is excellent. No one wants to eat fish raised in such water, and no one is distressed by the loss of such fish. This development model has great reference significance, and it is a very worthy case to solve the contradiction between environmental governance and economic development in China.

1. The relationship between economic development and environmental protection is interdependent and complementary. From the perspective of Scientific Outlook on Development, economic development and environmental protection are interdependent and complementary, and they are dialectical unity of objective economic laws and ecological balance. Scientific Outlook on Development adheres to the coordinated development of economy, society and environment. There is an old saying in China, "You can't have your cake and eat it". Developing the economy at the expense of polluting the environment is tantamount to killing the goose that lays the golden egg. Economic development depends on the environment. Environmental problems arise from economic development and must be solved in economic development.

2. Compared with economic growth, economic development is the core concept of development economics. Economic development refers to high-quality economic development including quality and quantity, not just the increase of quantity. With the socialization of production, the functionalization of knowledge and the economization of society, the economic structure becomes complicated, and economic growth and economic development, economic development and social development gradually converge in connotation and extension. GDP growth can no longer truly reflect economic growth. Even if economic growth is inseparable from economic development, economic growth has only abstract significance in today's era.
