Method for promoting recovery of marsh plants in wetland field blocks reverted from cultivated land in plain area

Abstract

The invention provides a method for promoting recovery of marsh plants in wetland field blocks reverted from cultivated land in a plain area, and relates to the method for promoting recovery of the marsh plants in the field blocks. The method aims to solve the problem that when a recovery process of reverting cultivated land to wetland is conducted on the cultivated land generated through moors in the edges of the wetland in the plain area in a reclamation mode, the plant diversity recovery effect is poor. The method includes the steps that 1, a wetland pant seed bank germination experiment is conducted on the soil of the wetland field blocks reverted from the cultivated land; 2, field block microtopography is built; 3, micro hydrology regulation is conducted on the field blocks; 4, vegetation recovery is conducted. According to the method, only the micro hydrological landscape within a small space scale is required to be improved, the work amount is small, manual interference is less, and the method is easy to implement; a local plant seed bank and plants are utilized, invasion of foreign species is avoided, and the rapid recovery ability of the plants is improved; the method is used for promoting diversified recovery of the marsh plants in the wetland field blocks reverted from cultivated land in the plain area.

Description

technical field [0001] The present invention relates to a method of promoting the restoration of swamp vegetation in a field. Background technique [0002] Wetlands are the ecological landscape with the richest biodiversity in nature and one of the most important living environments for human beings. Wetlands play an important role in maintaining regional ecological balance and protecting biodiversity. However, due to the influence of human activities, especially the policy of biased pursuit of food production in history, large swamps and wetlands in the plains have been reclaimed. Unreasonable large-scale reclamation and degradation of wetlands have affected the original ecological regulation, supply and support functions of wetlands, changed the stability of regional ecosystems, caused serious water and soil erosion, and frequent regional floods and droughts (Liu Xingtu, Ma Xuehui. 2002 . Sanjiang Plain Natural Environment Change and Ecological Conservation. Beijing: Scie...
