Embodiment 1

[0062] Embodiment 1 A method for identifying and evaluating damage to urban agglomeration ecological space, comprising:

[0063] Step 1 Identification of important ecological space landscape pattern of urban agglomeration

[0064] Including the identification of important value areas of ecosystem services, identification of important urban green spaces and water system patches, and identification of nature reserves;

[0065] Step 2: Diagnosis and identification of ecological space damage in urban agglomerations

[0066] Firstly, a 20km×20km fishing net grid is established for the urban agglomeration’s land use to cover the whole area, and the landscape pattern index inside different grids is calculated using the landscape pattern comprehensive index calculation formula respectively, and the landscape pattern comprehensive index value of different grids is obtained , and finally use the spatial analysis tool in ArcGIS10.5 software to interpolate the calculated values ​​to obta...

Abstract

The invention discloses a city group ecological space damage identification and evaluation method. The method includes: analyzing and identifying important landscape space patterns such as city groupecological source land and ecological galleries; on the basis, overlapping an urban group landscape pattern comprehensive index and an ecological service function conversion equivalent evaluation result brought by land utilization change to obtain urban group ecosystem damage space distribution; furthermore, combining on-site investigation and classification combing to summarize the typical ecological damage space type of the urban group, and carrying out cause analysis and damage state evaluation.

Description

Technical field: [0001] The invention relates to the field of environmental science and technology, in particular to a method for identifying and evaluating damage to an urban agglomeration's ecological space. Background technique: [0002] Urban agglomeration refers to a giant system composed of multiple cities of different nature, grade and scale in a specific geographical area. Urban agglomeration is the product of a country's industrialization and urbanization transformation and development to an advanced stage. It is a new feature of the world's urbanization development. It is often the hub for a country or a large region to enter the world, and the gateway for the world to enter the region. The growth pole of the region is also the most dynamic and competitive region. Urban agglomeration refers to the formation of a super-large or super-large city within a specific geographical range, with at least three metropolitan areas (districts) or large cities as basic constitu...
