Abstract

The invention discloses a method for evaluating the ecological safety early-warning level of a wetland, and relates to the field of ecological environments. The method comprises the steps: determining an early-warning system index factor according to a pressure-state-response model; obtaining a prediction value of a pressure index factor through a gray sequence prediction model; obtaining a land utilization simulated diagram of a particular year through a Clue-S model, combing with software FRAGSTATS, and determining a prediction value of a state index factor and a prediction value of a response index factor; employing an analytic hierarchy process to construct a judgment matrix, and determining the weight of each index factor of en early-warning system; determining an ecological safety index of each index factor of the early-warning system through a logistic growth curve model; and determining an ecological safety value of the wetland through a comprehensive evaluation method. The method can achieve the quantification of the early-warning level of the ecological safety of a corresponding region in future through a wetland ecological safety early-warning standard, and can the effective protection measures for the ecological environment of a regional wetland are proposed according to a specific prediction result.

Description

technical field [0001] The present invention relates to the field of ecological environment, and more specifically relates to a wetland ecological security early warning grade evaluation method. Background technique [0002] The Liaohe Estuary Wetland is located at the end of the Liaohe River Basin. It is an important part of the Liaohe River Basin. It is the largest estuary reed wetland in my country and an important natural ecological protection area in China. It is also one of the key research areas of the project. At present, with the country's effective control and treatment of pollutants in the upper reaches of the Liaohe River, the impact of water pollution on the estuary wetlands has been alleviated, and the ecological environment of the estuary wetlands has improved to a certain extent, but there are still many serious ecological environmental problems, such as : The wetland area continues to shrink, the biological resources decrease sharply, and the impact of human...
