Impact of Fast Urbanization on Ecosystem Health in Mountainous Regions of Southwest China

Abstract: Accelerated urbanization has changed land use patterns, leading to the deterioration of ecosystems. Assessments of ecosystem health (ESH) during the urbanization process are used to determine the reasons and mechanism for this, and to uncover negative factors. In this study, we assessed the ESH of Qiannan prefecture, in Guizhou Province, China, based on the ecosystem services value. We selected a series of indicators, including natural, social, and economic aspects, to detect the impact of urbanization on ecos… Show more

“…In addition, the vegetation coverage in this study area is high, and the main vegetation type is forest. Among all landscape types studied, forest is the landscape type with the highest resilience index [ 40 ]. This is another reason for the high level of ecosystem health in this study area.…”

“…Landscape heterogeneity was measured using Shannon’s Diversity index (SHDI), Shannon’s Evenness index (SHEI) and Patch Richness (PR) [ 39 ]. Landscape connectivity was quantified using the Patch Cohesion index (COHESION), Contagion index (CONTAG) and Interspersion Juxtaposition index (IJI) [ 40 ].…”

“…A positive I/I i kl value represents a positive spatial correlation between urbanization and ESH, which signifies that a unit with a high level of urbanization is surrounded by units with high ESH. A negative I/I i kl indicates a negative spatial correlation-a unit with a high urbanization level is surrounded by units with a low ESH [63]. The higher absolute value of I/I i kl indicates that the spatial correlation is stronger.…”

“…With the rapid development of human society, various ecological problems have become apparent. National and global ecological and environmental problems, such as energy shortages, water pollution, land degradation, biodiversity loss and the frequent occurrence of extreme weather, have emerged [ 2 , 3 ]. Urban expansion has affected large swathes of cultivated land, forest land and water.…”
