River ecosystem function determination method

Abstract

The invention discloses a river ecosystem function determination method, which is characterized by comprising the following steps in sequence: S1, preparing a determination device, S2, determining theposition of a monitoring station, and arranging an artificial substratum, S3, carrying out regular treatment and maintenance on the artificial substratum, S4, recovering the artificial substratum, and collecting a test sample, S5, determining related ecosystem function indexes. According to the invention, the method can complete monitoring of three different types of ecosystem functions (productivity, resolving power and stability) in the same period, so that multi-parameter data are provided for comprehensively evaluating and investigating the condition of the river ecosystem at the station,quantitative monitoring of ecosystem functions can be achieved, on the basis of further obtaining watershed water quality, hydrology, human activities and climate change parameters, the correspondingrelation of the ecosystem functions to environmental factors can be quantitatively analyzed, and powerful technical support is provided for evaluating ecosystem function health conditions of all monitoring stations and the whole watershed.

Description

technical field [0001] The invention relates to the field of environmental ecology, in particular to a method for measuring river ecosystem functions. Background technique [0002] The river ecosystem is a unity with a certain structure and function, which includes six components: inorganic substances, organic compounds, hydrological and physical and chemical conditions, primary producers, secondary consumers and top consumers participating in the material cycle. The functions of river ecosystems include the processes of production, consumption, and decomposition that aquatic biomes participate in. Therefore, the three basic functions of river ecosystems can be quantified by measuring the production and circulation of benthic algae and artificial organic matter in river ecosystems in the field: Productivity, resolution, stability. Among them, benthic algae are the primary producers in rivers, responsible for transferring inorganic nutrients to higher organic life forms, so ...

Problems solved by technology

However, there is no measurement method to reflect the intensity of human activities in the river basin, so people cannot scientifically and quantitatively grasp the health of the river ecosystem.
