Urban ecological red line early warning method and device based on human activity feedback

Abstract

The invention discloses an urban ecological red line early warning method and device based on human activity feedback, and the method comprises the steps: dividing an urban construction planning layout map corresponding to a target urban region into an agricultural land region, a construction land region and an unused land region; the human activity points reported in the unused land area are actually illegal land areas and have the maximum influence on urban ecology, and the current ecological red line danger degree value can be determined by calculating the influence value of the illegal land areas on the ecological area, so that early warning is given out; the technical problem that in the prior art, due to the fact that some small-range pollution areas cannot be accurately recognized, the judgment accuracy of the urban ecological condition is not high is solved, accurate recognition of the pollution areas is achieved, the error rate of mistakenly recognizing the pollution areas as residential areas is reduced, the judgment accuracy of the urban ecological condition is improved, and the urban ecological condition recognition efficiency is improved. And powerful technical support is provided for urban planning management and subsequent ecological environment improvement work.

Description

technical field [0001] The invention relates to the technical field of urban planning management and monitoring, in particular to an urban ecological red line early warning method and device based on human activity feedback. Background technique [0002] With the development of economy and society, people's yearning for a better ecological environment continues to increase, but driven by economic interests, there are always a large number of human activities that destroy the ecological environment. The urban ecological red line refers to the boundary control line in the environmental function zoning, which is of great significance to ensure the ecological security of the country and region and improve the ecological service function. The urban ecological red line mainly has the following five characteristics: The first is objectivity. It can reflect the natural geographical features and play a vital role in maintaining ecological security and improving ecological service fu...

The third is mandatory, through the adoption of strict environmental management measures to maintain, limit or prohibit development activities

The fourth is dynamic. The red line limit will change due to changes in the external environment, and must be adjusted in time to meet the needs of social changes.

Since the urban layout is dominated by residential areas, when identifying remote sensing images, some small-scale polluted areas cannot be accurately identified, or there are errors in misidentifying polluted areas as residential areas, resulting in a lack of understanding of urban ecological conditions. The accuracy of the judgment is not high, and it cannot provide strong support for the follow-up ecological environment improvement work

[0004] Therefore, there is an urgent need for an urban ecological red line early warning strategy based on human activity feedback to solve the problem that some small-scale polluted areas cannot be accurately identified in the existing technology, or there are errors in misidentifying polluted areas as residential areas. , resulting in a technical problem of low accuracy in judging the urban ecological situation
