Embodiment 1

[0042] like figure 1 As shown, this embodiment provides an urban-rural gradient construction method of the ecological importance of carbon sinks, which includes the following steps:

[0043] 1. Select the experimental area and collect data on carbon emissions, urban human activities, and land use;

[0044] The collected data includes Landsat8 remote sensing data, POI (Point of Information) data, and annual energy consumption converted into standard coal.

[0045] 2. Spatial distribution analysis of carbon sink capacity;

[0046] Carbon sequestration types are divided into aboveground biomass carbon pools, underground biomass carbon pools, dead organic matter carbon pools, and soil organic matter carbon pools; each land use type contains 4 carbon pools, as shown in Table 1, through carbon density equivalent Calculation of carbon sinks;

[0047] Table 1 The carbon density equivalent of each land type of the four carbon pools (unit: kg / m 2 )

Embodiment 2

[0073] This embodiment includes the following steps:

[0074] (1) Select the research area, prepare relevant data and data processing. There are many data acquisition and preprocessing methods, and this embodiment adopts common methods.

[0075] (a) Landsat8 remote sensing image data is classified by maximum likelihood method through envi5.3 platform.

[0076] (b) Use the urilib package of Python to capture all the location information of the research area from the POI interface of Baidu map. The json module is used to parse the returned data, and the csv module is used to store and manage the data. Since there are many captured data, time is required The module controls the script process to slow down the request frequency. Import to the ArcGIS platform, generate point shp files, and then correct the coordinates.

[0077] (c) Query the energy consumption data during the research period from the energy consumption statistical yearbook of the city's regional GDP included in ...

Abstract

The invention relates to the technical field of ecological system service, in particular to a carbon sink ecological importance urban and rural gradient construction method, which comprises the following steps of: 1, selecting an experimental area, and collecting carbon emission, urban human activities and land utilization data; 2, analyzing the spatial distribution of the carbon sequestration capacity; 3, simulating an urban logic carbon source according to human activities; 4, analyzing emission carbon space distribution according to an atmospheric diffusion model; 5, constructing an urban and rural gradient pattern theoretical model; 6, constructing a carbon sink ecosystem service urban and rural space pattern; and 7, pattern change simulation under multiple scenes. According to the method, the urban and rural gradient of the carbon sink ecosystem service can be well constructed and evaluated.

Description

technical field [0001] The invention relates to the technical field of ecosystem services, in particular to an urban-rural gradient construction method of the ecological importance of carbon sinks from the perspective of supply and demand. Background technique [0002] As the most concentrated area of ​​human activities, cities have very limited carbon sink capacity and can only transfer the ecological pressure of carbon sinks to the suburbs. The urban ecological zone is determined by the laws of nature and has a close ecological relationship with the city. The construction of ecological zones is the concept and idea of ​​solving urban ecological security. Reasonable division of ecological function zones is helpful to allocate information on ecosystem resources and reveal ecological and environmental problems. Carbon emissions are the demand side of ecosystem services, while carbon sinks in the urban hinterland are the supply side. The whole process of carbon emission, dif...
