A coastal wetland bird ecological health evaluation method

Abstract

The invention provides a coastal wetland bird ecological health evaluation method. The coastal wetland bird ecological health evaluation method comprises the following steps of S101, investigating andcollecting coastal wetland bird related data information; S102, establishing a coastal wetland bird ecological health evaluation index system based on bird community characteristics and habitat related parameters; S103, determining the characteristics and assignment standards of each level of index, bird community characteristics being mainly reflected by bird diversity evaluation, and habitat related parameters mainly reflecting the importance, the suitability and the risk of the wetland to the birds; S104, determining the weight of each level of index; S105, comprehensively evaluating the ecological health condition of the birds in the coastal wetland based on the health comprehensive index HCI; and S106, dividing the ecological health level of birds in the coastal wetland. According tothe coastal wetland bird ecological health evaluation method provided by the invention, the scientific, effective and standard management and evaluation can be performed on the mangrove forest wetland bird condition and the habitat state.

Description

technical field [0001] The invention relates to the field of ecological environment evaluation of birds, in particular to a method for evaluating the ecological health of birds in coastal wetlands. Background technique [0002] In the coastal mangrove wetland ecosystem, amphibians, reptiles, mammals and other higher trophic level animals are rare, while a large number of birds are representatives of the highest trophic level, which play an important role in maintaining biodiversity and ecological balance. effect. Birds are important members of the coastal wetland ecosystem and occupy an extremely important position in the coastal wetland ecosystem. [0003] The ecological health of birds refers to whether the habitat habitat and ecosystem are healthy for birds, that is, whether the ecosystem service functions can meet the needs of birds. Specifically, with birds as the main body, considering the factors of birds themselves, it is necessary to maintain a certain diversity, ...
