Coastal multiple habitat simulation test field

Abstract

The invention discloses a coastal multiple habitat simulation test field. The test field is characterized in that the test field is provided with a posterior coastal zone test area and a coastal saltmarsh wetland test area, wherein an intertidal zone test area is arranged in the posterior coastal zone test area, the intertidal zone test area is arranged at one side, close to the coastal salt marsh wetland test area, of the posterior coastal zone test area, the intertidal zone test area is equipped with two water outlet pipes towards the coastal salt marsh wetland test zone, and the two wateroutlet pipes are respectively arranged parallel to the bottoms of the test areas. The multiple habitat simulation test field designed in this way aims at realizing that a test field simulates a plurality of different coastal habitats at the same time, has obvious advantages such as simple structure, reusability and low cost, makes test results be not affected due to changes of the groundwater level and salinity, and be more accurate, ensures that saline groundwater is circulated in the test field, and does not affect the environment outside the field.

Description

technical field [0001] The invention relates to a coastal multi-habitat test field and a construction method thereof, in particular to a nestable coastal multi-habitat simulation test field and a construction method thereof. Background technique [0002] Coastal vegetation includes subtidal plants (such as seagrass), intertidal plants (such as mangroves and semi-mangroves), and supratidal salt-tolerant plants. Coastal vegetation restoration is the main content of coastal zone protection and ecological seawall construction. However, due to the lack of understanding of the root system, leaf salt tolerance and growth characteristics of many coastal plants, it has caused many difficulties in the implementation of coastal vegetation restoration. Therefore, it is necessary to establish a simulation test site with different coastal habitats. Salt capacity and adaptability to different habitats provide a test site, which can provide a reliable basis for coastal vegetation restoratio...

AI Technical Summary

Problems solved by technology

The disadvantage is that the cost is high and the habitat is single. It only simulates the coastal habitat of the land area, and other habitats such as salt marsh wetland, supratidal zone, intertidal zone, and subtidal zone are missing.

Moreover, the general field test sites are not equipped with groundwater circulation devices, which brings a lot of inconvenience to tests such as plant growth, soil moisture content, and groundwater quality. implement
