Abstract

The invention discloses a quantitative collection device and method for benthonic animals in water delivery channel, wherein the quantitative collection device comprises artificial matrixes, a steel wire rope, a sensor device, a display device and a retraction device; a plurality of artificial matrixes are fixed on the steel wire rope at intervals, the sensor device is fixed in the steel wire ropenear the artificial matrixes, the end parts of the steel wire rope are connected with the retraction device, so that the retraction device can wind and unwind the steel wire rope, and the display device electrically connected with the sensor device is also fixed on the retraction device. The invention solves the problem that the traditional collection method of benthonic animals is not suitable for channels with less sediment content, large flow velocity and water depth.

Description

technical field [0001] The invention relates to the field of water ecological environment monitoring, in particular to a quantitative collection device and method for benthic animals in water delivery channels. Background technique [0002] In the South-to-North Water Diversion Project, the main canal is a fully reinforced concrete structure and is not connected to the external water system. After the water is passed through, a large-scale complex ecosystem of reservoirs and main water delivery canals is formed, spanning multiple river basins and multi-climate zones. The conditions such as biogeochemical cycle and biogeochemical cycle are significantly different from those of natural rivers, and there is no mature experience for reference in the development direction of various elements of the ecosystem. As a long-distance water transmission project that has attracted worldwide attention, mastering the water ecological status and development trend of the central main canal i...
