Embodiment 1

[0031] An embodiment of the present invention provides an evaluation method for disaster prevention and avoidance capabilities of park green spaces, such as figure 1 As shown, the evaluation methods of the park's green space disaster prevention and risk avoidance capabilities include:

[0032] Step S1: Obtain image data information of the park green space system, extract target park green space data from the image data information, and acquire historical disaster data of the target park green space. Specifically, the data of the urban park green space system can be extracted from the high-resolution remote sensing map of the city. In practical applications, ENVI (The Environment for Visualizing Images) software can be used to extract the target park green space data.

[0033]Step S2: According to the green space data of the target park, each evaluation index of the disaster prevention and avoidance ability of the green space of the target park is screened, and the comprehensiv...

Embodiment 2

[0058] An embodiment of the present invention provides an evaluation system for disaster prevention and avoidance capabilities of park green spaces, such as Figure 7 As shown, the evaluation system of the park's green space disaster prevention and risk avoidance ability includes:

[0059] The data acquisition module 1 is used to acquire image data information of the park green space system, extract target park green space data from the image data information, and acquire historical disaster data of the target park green space according to the target park green space data. For details, refer to the relevant description of step S1 in Embodiment 1.

[0060] The evaluation index determination module 2 is used to screen the evaluation indexes of the disaster prevention and risk avoidance ability of the green space of the target park according to the green space data of the target park, and determine the comprehensive weight of each of the evaluation indexes. For details, refer to...

Embodiment 3

[0064] An embodiment of the present invention provides a non-transitory computer storage medium, the computer storage medium stores computer-executable instructions, and the computer-executable instructions can execute the method for evaluating disaster prevention and avoidance capabilities of park green spaces in any of the method embodiments above, Wherein, the above-mentioned storage medium may be a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), a random access memory (Random Access Memory, RAM), a flash memory (Flash Memory), a hard disk (Hard Disk Drive, abbreviation: HDD) or a solid-state drive (Solid-State Drive, SSD), etc.; the storage medium may also include a combination of the above types of memories.

[0065] Those skilled in the art can understand that all or part of the processes in the methods of the above embodiments can be implemented through computer programs to instruct related hardware, and the programs can be stored in a compute...

Abstract

The invention provides a park green space disaster prevention and risk avoidance capability evaluation method and system, and the method comprises the steps: obtaining the image data information of apark green space system, extracting the target park green space data from the image data information, and obtaining the historical disaster data of a target park green space; screening each evaluationindex of the disaster prevention and risk avoidance capabilities of the target park green land according to the target park green land data, and determining the comprehensive weight of each evaluation index; and according to the historical disaster data, each evaluation index and the comprehensive weight of each evaluation index, evaluating the disaster prevention and risk avoidance capability ofthe target park greenbelt, and generating an evaluation result. Through implementation of the invention, a unified evaluation standard is provided for disaster prevention and risk avoidance capabilities of park greenbelts; the evaluation result can visually reflect the disaster prevention and risk avoidance capability of the park green space, provides a theoretical basis for urban park green space disaster prevention planning, and has important significance for reinforcing the protection and development of park green space landscape resources, optimizing the disaster prevention capability ofan urban green space system, consolidating the stability of the green space system and the like.

Description

technical field [0001] The invention relates to the field of ecological resource evaluation, in particular to an evaluation method and system for disaster prevention and avoidance capabilities of park green spaces. Background technique [0002] Urban green space is a kind of urban land with vegetation as the main form of existence, which is used to improve urban ecology, protect the environment, provide recreational areas for residents and beautify the city. Urban green space plays an important role in improving the urban climate and environment, providing leisure life for residents, and preventing and avoiding disasters. Park green space is a large-scale green space in urban green space, which has a positive effect on residents' leisure life. Due to the large area of ​​the park green space, the disaster prevention and risk avoidance ability of the park green space directly reflects the structure and function of the entire urban green space system. The improvement of the sy...
