Embodiment Construction

[0027] The following embodiments are only used to illustrate the present invention, and the scope of protection of the present invention is not limited only to the following examples. Those of ordinary skill in the technical field can realize the purpose of the present invention according to the disclosure content of the present invention.

[0028] The sample plot area in the following example is located at the seaside of Qingshantou, Beihai City, Guangxi Province, and the sandy beach invaded by Spartina alterniflora is used as the implementation sample point. Except for Spartina alterniflora, there is basically no other vegetation in this sample site, and the surrounding beaches not invaded by Spartina alterniflora are mostly light beaches.

[0029] (1) Cutting: randomly set up multiple 5m x 6m beach quadrats, manually cut off the Spartina alterniflora inside, and leave stubble less than 5cm.

[0030] (2) Shade close to the ground: choose a sunshade net with a single layer o...

Abstract

The invention discloses a spartina alterniflora physical treatment and sand beach recovering method which includes the steps of firstly, manually or mechanically cutting spartina alterniflora to leave stubbles lower than 5cm; secondly, fixing a mesh shading mulch above the cut area, and allowing the mesh shading mulch to be close to the ground; thirdly, opening part of the mesh shading mulch, and digging out spartina alterniflora root systems to determine root system death; fourthly, recycling the mesh shading mulch; fifthly, recovering a clean sand beach after natural sea water washing. The method is low in cost, fast in achieving the required result, strong in recovering purpose and free of environmental pollution.

Description

technical field [0001] The invention relates to a method for physical treatment of Spartina alterniflora on coastal beaches and a beach restoration method, and belongs to the technical field of ecological engineering. Background technique [0002] Spartina alterniflora is a perennial herb belonging to the Gramineae genus Spartina, native to the Atlantic coast. In order to protect the beach, improve the soil, and green the beach, Spartina alterniflora was introduced in some sea areas of my country in the 1980s, and certain economic benefits have been achieved. Spartina alterniflora has strong adaptability and spreading ability. It has spread all over the southeast coastal beaches from the warm temperate zone to the subtropical zone in my country. It is widely distributed in Guangxi, Guangdong, Fujian, Zhejiang, Shanghai, Jiangsu, Shandong, Tianjin and Liaoning, etc. 10 coastal provinces. After the introduction of Spartina alterniflora into the intertidal zone, it will occupy...
