Monitoring Spatial Patterns and Changes of Ecology, Production, and Living Land in Chinese Urban Agglomerations: 35 Years after Reform and Opening Up, Where, How and Why?

Abstract

Abstract:Chinese urban agglomeration (UA) has gradually become a new world economic center and the strategic region of the "The Belt and Road Initiatives". The spatial patterns and variations of ecology-production-living land (EPL) profoundly affect UA's development and its ecological environment. Unfortunately, scientific understanding about the trajectories, patterns and drivers of EPL changes in Chinese urban agglomerations (UAs) since reform and opening up is still very limited. The aim of this paper was to monitor those characteristics during the last 35 years. Here, we proposed a new classification system of EPL, including ecology land (EL), industrial production land (IPL), agricultural production land (APL), urban living land (ULL) and rural living land (RLL) due to Chinese urban-rural dual structure. Then, we extracted EPL land from the Chinese LUCC product, which is the recently released remote sensing data product of high resolution spatial land use data in China at national level. Furthermore, we analyzed the spatial-temporal trajectories and driving factors of EPL for Chinese UAs during 1980-2015. The results showed that: (1) ULL and IPL in Chinese UAs were increased rapidly, while EL and APL were seriously decreased. (2) The growth patterns of ULL and IPL had shown a spatial heterogeneity. As to different regional UAs, the expansion rates of ULL and IPL ranked from high to low were as follows: eastern, central, western, and northeastern UAs. (3) National policies, population, and economy dominated the spatial-temporal changes of EPL in Chinese UAs. (4) The multi-planning integration in the structure of land use should be strengthened at UA-scale.

A proposal for the theoretical analysis of the interactive coupled effects between urbanization and the eco-environment in mega-urban agglomerations

“…In addition, theoretical studies to investigate the interaction between high-density agglomerations and resources and environment have gradually garnered attention from researchers. Meanwhile, field studies on the impact of high-density agglomerations on the eco-environment and its systemic regulations have been carried out in some areas (Hummel et al, 2013;Cao et al, 2017). Moreover, quantitative studies aimed at quantifying the resources and environmental carrying capacity in urban agglomerations aggregated at high density have just started.…”

Does Rural Production–Living–Ecological Spaces Have a Preference for Regional Endowments? A Case of Beijing-Tianjin-Hebei, China

“…Therefore, PLES simplifies the functional representation of land use characters in territory system by maximizing the differences of action direction and weakening the difference of intensity [6,7]. Current studies on PLES classification include basic classification system of production, living and ecology [38], composite system of production, living and ecology and interaction of three basic types [42], and extended system that divides production space into agricultural production and non-agricultural production [43]. From the practical perspective of territorial spatial planning, this study considered spatial dominant function as the primary principle, chosen to identify the basic system of production, living and ecological space classification (Table 1).…”

Do Energy Resource Curse and Heterogeneous Curse Exist in Provinces? Evidence from China

“…Sun and Si [39] use Chinese cross-sectional data from 1996 to 2008 and find that neither resource abundance nor resource dependency display a significant relationship with regional economic growth. Cao et al [40] conclude that the "energy resource curse" is not significant at the municipal level in China. Furthermore, Wang et al [41] and Chen and Kung [42] find that the varied rates of cities' economic growth are mainly due to cities' divergent conditions.…”
