Method for northern low hilly area river bank side zone ecological construction

Abstract

The invention discloses a method for northern low hilly area river bank side zone ecological construction, and relates to a method for ecologically constructing a river bank side zone. The method solves the problems of high cost, unreasonable tree species selection and limited ecological functions of an existing ecological restoration method for the low hilly area river bank side zone. The methodcomprises the steps that 1, the river bank side zone is trimmed; 2, arbors are planted on a bank of the river bank side zone, shrub plants are planted at the bottom of a bank slope, and herbaceous plants are planted on the slope surface of the bank slope; and 3, vegetation on the river bank side zone is watered or reseeded for maintenance. According to the method, the northern low hilly area riverbank side zone ecological construction is realized, so that the shear strength of the surface layer of soil of the bank side zone within a range of 0-1 m is improved by 50%, the vegetation coverage of the bank side zone reaches 95% or above, the water and soil conservation capacity in the bank side zone is obviously improved, the effect is good, the method is scientific and reasonable, the biodiversity is increased, and a good ecological function is achieved.

Description

technical field [0001] The invention relates to a method for ecological construction of river banks. Background technique [0002] The area of ​​low mountains and hills in northern my country is widely distributed, especially in the eastern region. Due to abundant precipitation resources, open valleys and curved river courses, it has become the source area of ​​large rivers in my country. Historically, due to the humid climate and fertile soil, the plants on both sides of the river in low mountain and hilly areas grew luxuriantly, forming a natural river bank, which played a huge role in windbreak and dike reinforcement, water purification, soil erosion control, and biodiversity maintenance. role. In the past half a century, due to the excessive use of human activities such as agricultural reclamation, deforestation, and sand mining, the area of ​​river banks in low mountain and hilly areas has shrunk, river banks have become deserted, vegetation has been severely damaged, ...
