The invention relates to a method for constructing a deep pool and a shoal in a straight river channel. In the method, a spur dike is arranged on the left bank side of the straight river channel, a bank slope on the opposite bank of the spur dike is protected by riprap, a diving guide wall is arranged on the left and right banks of the downstream side of the spur dike respectively, the discharge cross section of the river channel is shortened by the spur dike to increase the flow rate of water flow, the bottom of a river bed of a river reach between the diving guide walls on the downstream side of the spur dike is continuously scoured to naturally form the deep pool, and a dead water area or slow flow water area formed between the diving guide wall and the river bank becomes the shoal through long-term deposition. The method has the advantages that: the deep pool is naturally formed and becomes a rest place for aquatic organisms such as fishes and the like, and can become a shelter for the aquatic organisms such as the fishes and the like in a flood period; plants can be planted on the shoal, and the shoal can become an organism habitat different from the deep pool; and the complexity of a river channel structure and water conservation condition diversity can be increased or repaired, and river biodiversity, population composition and rare species conservation are facilitated.

The invention relates to a circular agriculture system and an implementation method thereof. According to a characteristic that different biological wastes can be highly efficiently cycled by various insects and small animals, an insect breeding factory is constructed; and insect and small animal proteasome and insect feces residue organic fertilizer are respectively utilized as an animal factory protein feed and a plant factory organic fertilizer. Therefore, carious animal and plant products with high added values can be produced with high yields. With modern advanced agricultural technologies and equipment, stereo cultivation is usually carried out with rare species, such that a unit yield of the types of factories reaches more than a hundred times that of conventional agriculture. With the products from the three types of factories, a wide variety of series downstream industry chain group can be developed, such that best economic benefit can be ensured. The three types of factories, downstream industry chain spaces and farmer residential spaces can be arranged in a rise building. The buildings can form a highly clustered production, management, residence, agriculture, industry and business integral community.
