Embodiment 1

[0029] Ecological reconstruction site: Lake waters between Xiaoji Mountain and Zhongdu Mountain in Taihu Lake, Wuxi. The area covered by the project is 16.6 hectares. Before the reconstruction, the succulents, wild lotus and wild gorgon in the water area were on the verge of extinction, and the tilapia was also on the verge of extinction.

[0030] Before the project is implemented: firstly, the vertical frame structure in the water area is composed of cement columns, steel pipe columns, and moso bamboo piles, and the horizontal structure is composed of 15*15 (m) moso bamboo frames; The water peanut wave-dispelling belt, two bamboo strips are 15m apart, and water peanuts are stocked in the middle. The height is determined by reference to the water level. The inside of the first bamboo strip is covered with plastic woven cloth, and the bottom is wrapped into a gabion, which sinks into the water. The upper part is connected to the bamboo piles of the wave-dissipating belt to filt...

Embodiment 2

[0043] Ecological reconstruction site: the waters of the lake between Jinyuan and Zhongdu Mountain in Taihu Lake, Wuxi. Before the reconstruction, the yam, wild lotus and wild gorgon in the waters were on the verge of extinction, as was the tilapia.

[0044] Before the implementation of the project: Set up wave-dispelling belts and water hyacinth areas in this area with about 400 mu of water surface, and build a new protection area around the water intake of the water plant. The setting of the wave-dissipating belt and the planting requirements of the water hyacinth area are the same as those in Embodiment 1, and will not be repeated here.

[0045] Implement the method of the present invention between the water hyacinth district and the newly-built protected area, and concrete operating steps are as follows:

[0046] In the first ten days of April, when the average temperature is above 15°C, cultivate the seedlings of Thai sharp-leaved cabbage in the dry land with convenient ...

Abstract

The invention discloses a method for reconstructing an ecosystem by using endangered aquatic organisms. The method comprises the following steps of: cultivating smilacina atropurpurea seedlings at the first ten-day period of April, and transplanting smilacina atropurpurea at the first ten-day period of May and managing; planting wild lotus at the first ten-day period of April and managing; planting wild ferox at the first ten-day period of April and managing; breeding tilapia at the beginning of May and managing; harvesting the smilacina atropurpurea from May to November; harvesting lotus seeds from July to September; harvesting wild ferox fruits at the second / first ten-day period of September; fishing the tilapia at the end of September; and removing stems and leaves of the wild lotus and ferox from water at December. One year after the ecosystem is reconstructed by the method disclosed by the invention, the aquatic organisms on the verge of extinction are rescued, and meanwhile, the water is purified, so that the aim of reconstructing the ecosystem is achieved. By using the characteristic that the tilapia eat algae, the average reduction rate of the alga number within a project at a blue alga outbreak period reaches 84.63% compared with the alga number without the project, and the difference of the algae within / without the project is remarkable, so that the project implemented by using the method disclosed by the invention has a remarkable benefit.

Description

technical field [0001] The invention relates to the field of rebuilding ecosystems, in particular to a method for rebuilding ecosystems using endangered aquatic organisms. Background technique [0002] The highest goodness is like water, water benefits all things. Water is the foundation of life and the source of development. The Party Central Committee proposes to build an ecological civilization and make China beautiful. According to the survey of the World Health Organization, 80% of the diseases in the world are related to drinking unsafe water. Purifying water quality and protecting water safety is an important project that requires continuous construction. [0003] Wuxi, adjacent to Taihu Lake, is beautiful and rich because of water. The beauty of Taihu Lake lies in the water of Taihu Lake. The ecological environment of Wuxi has been damaged to a considerable extent during the process of rapid economic development. At present, Wuxi is facing problems of water pol...
