Embodiment Construction

[0097] A method for ecological restoration of a water-fluctuating zone according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0098] For the test plants, the treatment area is set according to the natural altitude gradient, and a treatment area is set for every 1m of altitude, and various trees, shrubs and tall grasses are planted from an altitude of 163m, a total of 16 treatment areas; each treatment area, set 3 Repeating sections, low herbs are planted between them.

[0099] According to the provenance of the tested plants, the number of plants planted per square meter is different for each plant species, specifically: 24 plants of Chinese mosquito mother, long-leaf water hemp, autumn flower willow, small tree, boxwood leaf honeysuckle, and Kakailu, 15 Lycium barbarum, Metasequoia, Maple Poplar, Hangzi shoot, 12 Nanchuan willow, Chishan, 8 Shuihuazhi, 24 sweet root grass, vetiver; planted i...

Abstract

The invention provides a hydro-fluctuation belt ecological restoration method. The hydro-fluctuation belt ecological restoration method includes the following steps: observing the growth performance of test plants in a natural hydrologic condition through a hydro-fluctuation belt vegetation restoration test; measuring change of relevant physical signs of the test plants before and after waterflooding, and comparing the waterflooding resistance; adopting a suitable simple engineering measure to fix the plants for different life forms of plants, relieving water flow impact through the engineering measure, achieving water backflow in a small area, depositing sludge, and gradually improving the soil fertility condition; constructing different types of plant communities having different heights and different habitat conditions; and observing composition change and a natural succession condition of artificial plant communities. The beneficial effects of the invention are that the species richness of the plant communities can be greatly improved, the cover degree of the vegetation is increased, the diversity of species is improved, and the complexity and the stability of a space structure of the plant communities can be improved.

Description

technical field [0001] The invention relates to the technical field of ecological environment protection and management, in particular to a method for ecological restoration of a water-fluctuating zone. Background technique [0002] After the official completion of the Three Gorges Reservoir, with the annual operation of the reservoir, a permanent ebb and flow zone with a vertical drop of 30m (145-175m) will be formed on both banks. The Riparian zone, also known as the Riparian zone, the Riparian zone, the Riparian zone, etc., refers to the land that is submerged in rivers, lakes, and reservoirs due to seasonal water level fluctuations. It periodically emerges from the water surface and becomes a special area of ​​land. Due to the change of the hydrological regime of the Yangtze River, it will have a huge impact on the existing plant communities in the water-fluctuation zone, and the future development and succession of the plant communities in the water-fluctuation zone wi...
