The invention relates to a method for forming an ecological embankment of vertical revetment live branch bundles. The method is characterized in that a row of wood piles or concrete imitative wood piles is driven along the bankside toe line of a riverway, twigs of willows, alders or black poplars are bunched into live branch bundles, gravels, pebbles, haydites and zeolites are filled in the live branch bundles, and the live branch bundles are arranged between the wood piles or the concrete imitative wood piles and the bankside of the riverway parallel to the riverbank. Therefore, the problems of renovating vertical revetment waterfront plants along the riverway and constructing an ecological embankment are solved. The live branches used by the embankment have good tolerance to water logging, thereby quickly budding and forming a vegetation system, creating good living environment for riverbank living things, and beautifying riverbank landscape, and on the other side, plants, purifying filter materials and surface-attached microorganisms have better purifying effects on pollutant and improve the water quality of the riverway. The embankment is very convenient to construct, maintain and manage, and has better transformation and application prospects of the ecological renovation of the vertical revetment.

The invention provides a method for increasing the afforestation survival rate of quick growing tree species in a coastal saline-alkali land through catchment, salt leaching and water retention. The method comprises the steps of platform field building, wherein earth cutting and bed hedgehopping are performed on a section to be afforested to form an east-to-west platform field and a drainage ditch before a rainy season in the first afforestation year, the length of the platform field is 50-100 m, the width of the platform field is 20-50 m, the platform field is 1-1.5 m higher than the ground surface, the drainage ditch is 1-1.5 m lower than the ground surface, a cofferdam is built at the periphery of the platform field, the height of the cofferdam is 0.8-1.2 m, and the width of the cofferdam is 0.5-1.0 m. The method has the advantages that due to the fact that the platform field is small and convenient to construct, the soil salt content can be quickly decreased in half a year to one year through catchment, and the salt leaching speed is high; through comprehensive film mulching, soil moisture evaporation can be effectively reduced, salt content increasing can be prevented, and it is guaranteed that leached salt cannot rise to the ground surface layer; meanwhile, water can be retained, weed growing can be inhibited, the survival effect on black poplar, willow and elm seedlings which are poor in salt tolerance and high in water requirement is significant, and the problem that afforestation of black poplar, willow and elm trees is difficult in a saline-alkali area can be significantly solved.
