“…Therefore, it is essential to better understand the carbon dynamics of urban ecosystem, rather than relying on the assumption of static carbon stocks. In other words, it is not very important to account for the proportion of total carbon stocks at a regional scale that is stored in urban areas (Liu and Li, 2012); instead, it is necessary to quantify gradient changes in terrestrial carbon stocks in response to urban land use and cover change (Patak et al, 2006;Alberti and Hutyra, 2009;Hutyra et al, 2011b;Ren et al, 2011;Zhang et al, 2012), which is vital for understanding the effectiveness of policy implementations for preservation of carbon stocks in urban areas.…”

a b s t r a c tEcosystem services in urban areas are regarded as multiple environmental benefits fostered by urban-rural landscapes. A wide range of ecosystem services have been largely affected by land use and cover change in urban areas, leading to significant variation of ecosystem services, such as terrestrial carbon stocks across a gradient of urbanization. Urban areas are critical for terrestrial carbon dynamics owing to both considerable amount of biomass and soil carbon stored in cities and significant losses in carbon stocks from urban land use and cover change. We used Changzhou, a typical fast-growing city in China, as a case study, and estimated biomass and soil carbon stored in land covers using the InVEST model. We also quantified gradient changes in terrestrial carbon stocks in response to urban land use and cover change along two sample transects as a function of distance from the urban center. We found that carbon densities decreased with increasing intensity of urban development. Gradient transect analyses revealed an overall trend of increasing carbon stocks from the urban center to peri-urban areas as a direct result of land use and cover change driven by policy-oriented urban planning, which led to both infilling of empty areas within the urban center and sprawling of urban land toward peri-urban areas. As recent growth trends continue, the expansion of urban land markedly decreased areas previously dominated by green open spaces, making urban land use and cover change and losses in carbon stocks an increasingly important component of regional carbon dynamics. We proposed measures to mitigate these negative effects of urbanization on carbon stocks both for densely built-up areas and for rapidly urbanizing peri-urban areas.

“…Urban greenbelt of urban development pattern is inspired by Howard "garden city" theory, banded oxygen source of green space in city construction, thus a circular carbon sinks as far as possible to keep the city state of carbon balance, this kind of layout is mainly effected by the city green space around [9]. The city group layout structure forming ring green belt, and combined with large ecological forest, city, forest blend of circumferential layout structure [10] (Fig.3).…”

Abstract. Rising CO 2 is predicted to impact global warming, and the city is the most important carbon source. Based on the theory of unban carbon sink , we surveyed the the most important carbon source and sink inffect factor, and take them as the constraint conditions of urban ecological space by calculating different kinds of carbon sink. Depended on the spatial analysis of GIS, we form the whole low-carbon network of the green city with the source of oxygen outside, greenbelt-greenheart inside and neighbor-greenland by the qualitative and quantitative analysis method. At the end, optimize the urban ecological spatial pattern in urban low carbon, which is conducive to help urban to become more perfect on planning and development.

“…High atmospheric CO2 might have also resulted in increment of absorption of CO2 by sea water, making the ocean more acidic, with potential disastrous impact on marine vegetation, fish, animals and coral reefs. Thus, technically and economically feasible strategies are needed to mitigate the consequences of increased atmospheric CO2 (Zhang et al (2012).…”
