Embodiment Construction

[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Research methods:

[0025] Four indicator plants were selected in this study: Kobresia tibetica, Kobresia pygmaea, Carex scabrirostris and Carexmuliensis. Kobresia tibetan is a planting species of mounds, while Kobresia alpina is a typical indicator species of alpine meadow, and the transitional degradation status of alpine wetland to alpine meadow is usually evaluated according to the existence or disappearance of the above species. Carex sylvestris and Carex muli are typical indicator species in alpine marsh depressions, and they have considerable biomass in low-oxygen environments. Therefore, their productivity in depressions can be used to evaluate the surface water conditions in depressions.

Abstract

The invention discloses a research method for a succession process mechanism of a three-river-source alpine marsh wetland, and belongs to the technical field of environmental engineering, and the method comprises the following steps: selecting four indicating plants: Kobresia tibetica, Kobresia pygmaea, Carex scabrirostris and Carex muliensis. according to the method, hilly depression microtopography degradation of the alpine marsh wetland is a progressive process of transition from a primary wetland to a dry wetland and finally transition to an alpine meadow. The research result of the invention is beneficial to comprehensive understanding of the degradation process of the three-river-source alpine marsh wetland ecosystem.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and relates to a research method for the mechanism of the succession process of the Sanjiangyuan alpine swamp wetland. Background technique [0002] The hilly-sag micro-topographic features of the Sanjiangyuan alpine swamp wetland reflect the transformation process from healthy wetland to degraded wetland. By studying the micro-topographic features of hills and depressions and the changes in vegetation community structure and soil properties, the characteristics and evolution process of wetland degradation can be reflected. First, wetland degradation leads to the succession of plant community structure, which in turn changes the physical and chemical properties of soil. In addition, wetland degradation alters soil texture, soil organic matter, and nutrient depletion, thereby affecting microbial activity and communities, further affecting soil mineralization. During degradation...
