Method for evaluating ecological health of rare waterfowl

Abstract

The present invention discloses a method for evaluating the ecological health of a rare waterfowl. The method comprises: S1: analyzing the stomach residue of a rare waterfowl and the manure components; S2: analyzing the typical biological species of the waterfowl habitat and the [delta]15N[delta]13C and [delta]33S characteristics of the rare waterfowl by using an isotope detection technology; S3: indicating the enrichment status of the pollutant enrichment sensitive organ tissues in the rare waterfowl by using the level of the heavy metal enriched in the in vitro tissue of the rare waterfowl; and S4: collecting the vitro tissue of the rare waterfowl, determining the content level of the typical heavy metal enriched by the in vitro tissue, and referring the critical content of the existing heavy metal element producing the side effects to obtain the ecological health condition of the experiment sample rare waterfowl. With the method of the present invention, in the case of no influence on the population stability and no violation of the law, the enrichment degree of Cd in the rare waterfowl is accurately determined, and the ecological health status of the population can be reflected.

Description

technical field [0001] The invention relates to the field of environmental toxicology, in particular to a method for evaluating the ecological health of rare waterfowl. Background technique [0002] my country's wetland area is about 65.94 million hectares. These wetland swamps have become habitats and breeding grounds for many rare waterfowl. In recent years, due to the dual effects of strong human disturbance and natural factors, the ecological environment quality of wetlands has been significantly degraded, which also leads to the accumulation of heavy metals such as Cd in the wetlands. There are records of death due to heavy metal poisoning such as Cd in many rare waterfowl breeding grounds, migration stopovers and wintering grounds. This may be one of the reasons why the number and scale of many rare waterfowl populations have declined sharply, and are even on the verge of extinction. However, because these rare waterfowl (especially endangered rare waterfowl) are ra...

AI Technical Summary

Problems solved by technology

However, because these rare waterfowl (especially endangered rare waterfowl) are rare in number and protected by law, it is difficult for people to obtain corresponding biological samples and conduct related monitoring experiments, which makes the threat of rare waterfowl by environmental pollution and their ecological health very difficult. hard to understand

This has directly led to so far no research on the ecological health of rare waterfowl in this area. How to measure the degree of Cd enrichment in wild rare waterfowl without affecting the stability of their populations and violating the law has become the whole world Research on the ecological health of rare waterfowl and crucial issues to be solved in ecological protection
