Embodiment 1

[0024] The present invention is mainly based on the hazard characteristics of the development of key industries, starting from the safety of urban agglomeration human settlements, constructing an evaluation index system from the aspects of key industry development risk sources, exposure, vulnerability of receptors, and risk prevention and control capabilities, and proposes to develop urban agglomeration Ecological risk assessment method for regional key industry development. Those skilled in the art can realize that the described embodiments can be modified in various ways or combinations without departing from the spirit and scope of the present invention. Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] The key industry development ecological risk evaluation method described in the present invention comprises the following steps:

[0026] 1) Evaluation index system construction unit: establish an ecological r...

Embodiment 2

[0038] On the basis of the method in Embodiment 1, the Yangtze River Delta urban agglomeration is taken as an example to describe in detail.

[0039] Table 1 shows the ecological risk evaluation index system for the development of key industries in the Yangtze River Delta urban agglomeration. According to the characteristics of the Yangtze River Delta urban agglomeration, the evaluation index system constructed includes 1 target layer, 4 criterion layers, 10 element layers and 25 index layers. The evaluation indicators of each criterion layer and element layer include multiple different index layer evaluation indicators.

[0040] Refer to the statistical yearbooks, environmental status bulletins, environmental quality reports, water resources bulletins, and environmental statistics of the provinces and cities where the Yangtze River Delta urban agglomeration is located, as well as the 1km×1km Chinese population spatial distribution kilometer grid shared by the Resource and Envi...

Abstract

The invention discloses an ecological risk assessment method based on urban agglomeration region key industry development. The method comprises the five steps of evaluation index system construction,information input, index grading evaluation, index weight determination and evaluation management. And evaluating the evaluation index system according to the weight of the evaluation index, the variable information of the index, the index variable quantification standard information and the comment grade information, evaluating the urban agglomeration key industry development ecological risk degree, determining main factors of ecological risk influence, and proposing adjustment and control suggestions. According to the method, the influence degree of key industrial development on urban agglomeration ecological safety is investigated by taking human settlement ecological environment safety guarantee as a gripper, so that the ecological risk of urban agglomeration region key industrial development is evaluated, a basis is provided for decision making, and the decision making time cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ecological risk assessment, in particular to the ecological assessment of the development of key industries in urban agglomeration areas, specifically an ecological risk assessment method based on the development of key industries in urban agglomeration areas. Background technique [0002] The development of urban agglomerations is not only an important carrier for the development of modern urban agglomerations, but also an important support for the sustainable growth of urban economy and the enhancement of regional competitiveness. Under the double threat of high population concentration and heavy chemical industry-led development, serious ecological and environmental crisis problems have emerged in urban agglomerations. The industrial structure dominated by heavy chemical industry has kept resource consumption and pollution emissions high. Environmental pollution such as pollution is increasing day by d...
