Spatial distribution of carbon storage function and seismic damage in wenchuan earthquake stricken areas

Abstract

The value of terrestrial ecosystem carbon sequestration services has been widely recognized. Forests, grasslands and other ecosystems can store large amounts of carbon, which is the key to mitigating global climate change. The eco鄄 environment of the western region of Sichuan Province was greatly destroyed by the earthquake which had occurred in Wenchuan on May 12, 2008. One of the direct impacts is that the landscape was seriously damaged and the disturbed eco鄄 system released a significant amount of carbon dioxide because of sudden changes inland utilization and vegetation cover. Our goal was to use the maps of land use and land cover types and data of carbon reserves stocks in four carbon pools to estimate the amount of carbon stored in a landscape currently and the pre鄄seismic amount of carbon in the earthquake鄄hit areas, and then we have got a series of maps which can help us to conduct carbon management. Based on the geographical information system software of ArcGIS, this paper presented the evaluation index system to assess the carbon storage function of the earthquake鄄hit area, by calculating the density of carbon storage for four carbon pools (aboveground biomass, underground biomass, soil carbon and dead organic matter) in each grid. In addition, this paper also analyzed the spatial pattern of carbon storage function in this area. The results showed that the total carbon storage volume of the earthquake鄄hit

Ecosystem service trade‐offs and synergies and their drivers in severely affected areas of the Wenchuan earthquake, China

“…This catastrophic earthquake triggered thousands of landslides (Yang et al, 2018), resulting in direct damage to vegetation that has been challenging to recover (Yang et al, 2020). The water conservation function of the forest ecosystem in the affected area noticeably decreased (Wang et al, 2009; Zhu et al, 2020), and there was a significant threat to the carbon sequestration capabilities of forest vegetation (Peng et al, 2013). Moreover, the earthquake‐affected region is a biodiversity hotspot, and habitats of numerous rare and endangered plants and animals have been impacted to varying extents (Bao & Pang, 2008; Ouyang et al, 2008).…”

“…Second, Xu et al [32] complement this analysis with a broad spatial assessment of biodiversity, identifying two biodiversity hotspots ( the Minshan region and the southern Qionglai mountain region) where establishing a protected ecological corridor would greatly enhance biodiversity conservation. And, third, Peng et al [33] map and quantify the carbon storage in the earthquake area, finding a significant decline in carbon storage of ca. 10伊10 6 t in elevations of 750-1750m asl.…”

Exploring ecosystem carbon storage change and scenario simulation in the Qiantang River source region of China

“…28,29 However, the value of carbon storage which is generated by land-use change over a certain period in the future has been rarely assessed by scholars and few studies used the InVEST model to study the impact of land-use change on carbon storage in terrestrial ecosystems in the Qiantang River Source region. 30 Based on previous studies, this paper estimates the economic value of carbon storage in 2030 and analyses the impact of land-use change on carbon storage, to make the ecosystem carbon storage more complete. In recent years, researchers have studied the prediction of ecosystem carbon sequestration services from a land-use perspective.…”
