Abstract

Land is potentially major carbon stocks that could play an important role in offsetting anthropogenic carbon emissions, and land use/cover change (LUCC) have become the second largest anthropogenic carbon source after fossil fuel combustion. As a country with the largest number of resource-based cities, China faces greater pressure on the ecological environment, and the mining activities are an important driver force of LUCC in China’s resource-based cities. Therefore, studying the relationship between LUCC and carbon storage in China’s resource-based cities are of great significance to understand the influence mechanism of ecosystem carbon cycle, and contribute to the development of land use planning under the concept of green development. Based on the remote sensing images of 1987, 2004, and 2016 of Wu’an City, with the help of ArcGIS tools and InVEST model, this paper analyzed LUCC and dynamic ecosystem carbon sequestration of Wu’an city, and the main research contents and conclusion are as follows:

(1) Between 1987 and 2016, there was a significant change in land use types in Wu'an, which is reflected in the increase of forest, grassland and built-up land and the reduction of cropland, industrial and mining land and water bodies.

(2) From 1987 to 2016, the carbon storage increased, but the carbon sequestration potential decreased in Wu'an, and there are significant differences in the changes of carbon storage and carbon sequestration in different land use types.

(3) The carbon sequestration capacity of different land use types showed a high consistency with the carbon density values.

(4) Carbon sequestration capacity of different land use types in Wu'an was ranked as follows: forest > grassland > cropland > industrial and mining land > built-up land > water body.

In summary, this study can provide suggestions for the optimal allocation of land use in Wu'an, and provide theoretical basis for the coordinated development of economy and ecology of resource-based cities.
