Evaluation method for ecosystem health of coastal waters

Abstract

The invention discloses an evaluation method for ecosystem health of coastal waters, which comprises the following steps: constructing an ecological environment evaluation index system of the coastal waters; determining the ecological environment evaluation indexes and the weights of evaluation factors thereof; detecting and collecting the data of each evaluation factor of the ecological environment evaluation index and calculating the evaluation values of the indexes; calculating the evaluation values of the water environment ecological indexes of each station; calculating the evaluation values of the costal waters; and calculating the ecosystem health indexes of coastal waters. The evaluation results obtained by the evaluation method proposed by this invention can basically reflect the large man-made disturbances, such as the pollution caused by sewage entering into the sea, artificial breeding, petroleum pollution and so on, which cause the pressure on the ecological system of the coastal waters, and the main pollution risk factors, and provides a certain role in early-stage warning for the potential pollutant factor. The invention has certain reference value and reference significance, which can provide scientific basis and guidance information for the ecological protection and management of the coastal water ecosystem in the future.

Description

technical field [0001] The invention relates to a method for evaluating the health of the coastal sea area ecosystem. Background technique [0002] As the ecological environment is increasingly threatened by human activities and environmental pollution, the research on ecosystem health has attracted more and more researchers' attention in recent years, and has become one of the hot spots in the field of ecology and environment. The ecosystem provides human beings with various services in terms of natural resources and living environment, and is the existence that sustains life on earth. Ensuring the health of the ecosystem is the prerequisite for humans to obtain multiple services continuously, and it is also one of the reasons why humans pay attention to the health of the ecosystem. [0003] Ecosystem health has brought a new way of thinking and goals to environmental management. It looks at the diseases of the ecosystem from a holistic perspective, and tries to treat or p...

Problems solved by technology

As a comprehensive science and ecological practice, ecosystem health science aims to objectively measure the health level of ecosystems, thereby providing relatively correct countermeasures and methods for relevant departments and the public. However, due to the complexity and diversity of ecosystems, Cannot use a specific indicator (such as the original state) as a reference
