Abstract

The invention discloses an improvement structure for a low-lying land of a sandy riparian zone in a cold area. The improvement structure is as follows: a trumpet-shaped opening is arranged between a main river channel and a riparian zone; the elevation of the opening is lower than an ordinary water level of a river; an inverted trapezoidal ecological ditch is dug along an original terrain with theopening as a starting point; foreign soil is neatly laid in the interior of the ecological ditch; hygrophilous vegetation is planted on the surface of the foreign soil; Salix brachypoda is planted inboth bank slopes of the ecological ditch by cutting or transplanting; trees are planted on the edges of the ecological ditch; an inverted trapezoidal ecological pond is formed at the terminal position of the ecological ditch by utilizing an original dish-shaped low-lying land; foreign peat boggy soil are arranged at the bottom of the ecological pond; aquatic vegetation is planted at the bottom ofthe ecological pond; the hygrophilous vegetation is planted in the waterfront area of the bottom of the ecological pond; and the Salix brachypoda is planted in the bank slopes of the ecological pondby cutting or transplanting. The structure provided by the invention can improve sandy soil and vegetation habitat and conserve water and soil.

Description

technical field

[0001] The invention relates to a depression reconstruction structure in a sandy coastal zone in a cold region. Background technique

[0002] Affected by reclamation, grazing, and natural erosion, the original swamp peat soil in the Songhua River Basin has gradually evolved into a weedy meadow soil with a large sand content, and the formation of different sizes of discs due to the construction of soil. Depressions lead to bare land patches in the riparian zone, reduced vegetation coverage and diversity, and lead to poor water and soil conservation capabilities.

[0003] Based on the above problems, it is necessary to provide a reconstruction structure for sandy coastal depressions in cold areas that can improve sandy soil, improve vegetation habitat, and maintain water and soil. Contents of the invention

[0004] The technical problem to be solved by the present invention is to provide a structure for improving sandy soil, improving vegetation habitat, and...
