A method for constructing an in-situ water ecological experiment environment

Abstract

The invention provides a method for building an in-situ water ecology experimental environment. The method comprises the following steps that a supporting platform composed of vertical rods and a net-shaped bracket is constructed, the lower ends of the vertical rods are inserted into mud underwater, and the net-shaped bracket is located over a water surface; buckle belts are installed at the tops of enclosures, connection lines are installed in the middles of the enclosures, and gabions are installed at the bottoms of the enclosures; and all the enclosures are connected with the net-shaped bracket through the buckle belts and separate water bodies inside the enclosures from water bodies outside the enclosures, the gabions are buried in a mud layer underwater, ground anchors are installed at the bottoms of the enclosures, and all the enclosures are integrally connected through the connection lines. According to the method for building the in-situ water ecology experimental environment, firstly, the upper portions of the enclosures are fixed, and an experimental region is determined; secondly, all the enclosures with the positions determined are put into the water bodies, and the bottoms of the enclosures are fixed; and finally, all the enclosures are connected; disturbance to the water bodies in the process is small, an in-situ water ecology environment inside the enclosures is ensured, and an obtained result can well reflect the real situation of natural ecosystems; and the multiple enclosures form a enclosure group, controlled experiments are formed among all the enclosures, and multiple groups of experimental data can be obtained.

Description

technical field [0001] The invention relates to a method for constructing an in-situ water ecological experiment environment, belonging to the technical field of ecological environment engineering. Background technique [0002] Rivers, lakes, reservoirs, streams, and wetlands provide most of the water for drinking, agriculture, sanitation, and industry. However, human activities are increasingly frequent and profoundly affecting the water ecosystem. The eutrophication of my country's water environment is showing a trend of accelerated deterioration. The ecosystems of rivers and lakes have been seriously degraded. [0003] The eutrophication of water body causes the rapid growth and reproduction of algae to form "algae bloom", which has already caused disastrous consequences. Controlling the excessive growth and reproduction of algae is an important content in water environment management and water source protection. Existing algae control technologies include chemical method...

Problems solved by technology

[0004] The enclosure experiment needs to form an experimental area in the experimental water area. The water body in the experimental area is required to be completely isolated from the water body outside the experimental area. The formation of the existing experimental environment is to isolate the water body through the enclosure. The bottom of the enclosure sinks into the bottom of the water, the bottom of the enclosure is fixed, and then the upper part of the enclosure is fixed. This method of isolating the water body from the bottom has the following disadvantages: 1. When isolating the water body, it will disturb the sediment at the bottom of the water and affect the original ecology environment; 2. Most of the on-site enclosure experiment devices are large in size and high in cost, and are not convenient for transportation and storage, which brings certain difficulties to the promotion and popularization of the enclosure method; 3. The assembly method of some field enclosures that can be assembled is too large. It is cumbersome, resulting in a very labor-intensive on-site operation, and the connection between parts is not strong enough. During the experiment, the water body isolation failure caused the experiment to fail.
