Abstract

The invention discloses a method for recognizing influences of a grassland vegetation root system on slope runoff. The method comprises the steps that grassland vegetation in a research region is analyzed to obtain N grassland vegetation types and respective areas; according to the N grassland vegetation types, representative experiment sample plots are selected respectively to perform sampling, grassland vegetation aboveground biomass and grassland vegetation underground biomass are obtained, and specific values of aboveground-underground biomass of different grassland vegetation types are calculated; a comprehensive specific value of grassland vegetation aboveground-underground biomass is obtained; the grassland vegetation aboveground biomass in the research region is obtained through inversion; the grassland vegetation underground biomass in the research region is obtained; runoff data in the research region is acquired; and by establishing the relation between the grassland vegetation underground biomass and the runoff in the research region, the influences of the grassland vegetation root system on the slope runoff are quantitatively recognized.

Description

technical field [0001] The invention relates to the technical fields of hydrology and water resources, in particular, the invention relates to a method for identifying the influence of grassland vegetation roots on slope runoff production. Background technique [0002] Grassland vegetation cover changes affect the largest global land surface area and are therefore closely related to the level of ecosystem health. Unreasonable grassland vegetation coverage directly causes the quantity and quality of grassland vegetation to decline. In addition, problems such as climate, hydrology and geological disasters caused by changes in the underlying surface also emerge in endlessly. The decline in the quantity and quality of surface vegetation has caused an imbalance in the global climate system, accelerated the destruction of other biological habitats, and reduced biodiversity. [0003] Grassland vegetation maintains water and soil, conserves water sources, and improves soil fertilit...
