Embodiment 1

[0015] 1. Site selection: by the lake, first choose a place with no tree shade or high-rise buildings within 30m, and no sun shelter after 9:00 in the morning and before 5:00 in the evening. Use cement to make it 10m long, 5m wide, and 2.5m deep with water inlet and drainage. A convenient 9-hole experimental pool; 20cm of lake mud is laid on the bottom of the pool. In May, 10% of the total area of ​​the experimental pool is planted with bitter grass and Hydrilla verticillium in the middle of the experimental pool to allow them to grow naturally.

[0016] 2. Experiment time: choose to start the experiment on a day when the water temperature is 24-28°C and there is sunshine for more than 7 consecutive days. The experiment period is 7 days.

[0017] 3. Experiment:

[0018] 3.1 Change the water group: 3 days before the experiment, 100% of the lake water was used to change the water of the experimental pool once, so that the water depth was 2.0m; the experimental pool was divided i...

Abstract

The invention discloses a determination method for the value of conversion from nitrogen and phosphorus in water to primary biological and ecological capacity. The method comprises the steps of site selection, experiment water design and construction, arrangement of an experiment pond, determination of experiment time, performance of a specific experiment and the like. Through the determination method, the value of conversion from the nitrogen and phosphorus in the water of a lake or reservoir to the primary biological and ecological capacity can be obtained through statistics, the biological and ecological capacity of the lake or reservoir can be further grasped, the value of the biological and ecological capacity is used for deciding the socking quantity and catching quantity of aquatic organisms in the water of the lake or reservoir, therefore, the water of the lake or reservoir is protected, and certain economic benefits are generated continuously. Besides, the determination method is high in operability and reliable in data result.

Description

technical field [0001] The invention relates to the field of biological and environmental ecology research methods, in particular to a method for measuring the conversion value of nitrogen and phosphorus in lakes and reservoirs into primary biological ecological capacity. Background technique [0002] In this paper, biological ecological capacity refers to how many organisms can be naturally produced in an environment without any artificial intervention. This is fundamentally different from the currently proposed biological capacity K (the maximum amount of biomass that can be accommodated in a certain environmental area under artificial intervention, exceeding this value, the ecological environment will suffer serious damage). [0003] With the development of the economy, artificial intervention in the natural world is becoming more and more serious, and the results of the intervention are reflected in the deterioration of water quality, frequent changes in the weather, the...
