Abstract:In recent years, changes in land use resulting from rapid urbanization or urban sprawl have brought about many negative effects to land ecosystems, and have led to entropy increases. This study introduces the novel ideas of a planning regulation coefficient for sustainable land-use planning in order to decrease entropy, combined with the CLUE-S model to predict land-use change. Three scenarios were designed as the basis for land-use projections for Guangzhou, China, in 2015, and the changes in the land ecological service function for each scenario were predicted. The results show that, although the current land-use plan is quite reasonable, it will be necessary to further strengthen the protection of farmland and important ecological service function areas.

“…These changes have likewise led to heavy losses in humans' living space and damaged the sustainable development of human society. Ecological security has thus become so important that it risks affecting both state security and sustainability of social development (Solovjova 1999;Gong et al 2009;Li et al 2010). Ecological security analysis evolved from the study of ecological risk and ecological fragility, which have been developed all over the world (Forman and Godron 1986;Kong et al 2002;Rapport 1993;Ryan 1998).…”

Regional landscape ecological security is an important issue for ecological security, and has a great influence on national security and social sustainable development. The Pearl River Delta (PRD) in southern China has experienced rapid economic development and intensive human activities in recent years. This study, based on landscape analysis, provides a method to discover the alteration of character among different landscape types and to understand the landscape ecological security status. Based on remotely sensed products of the Landsat 5 TM images in 1990 and the Landsat 7 ETM+ images in 2005, land-

“…The spatial heterogeneity of ecological security exits between regions and this should be considered in future urban planning. The area of insecurity and rapid degradation are mainly located industrial development area [25] and densely populated area [90]. In our study area, QiMeng County, Yi County, and Huangshan District, which are located in the northwestern part of the city, generally remain at a high level of landscape ecological security, as shown in Figure 8.…”

“…The landscape (2) Pressure-State-Response Framework for Evaluating LES In this study, the P-S-R framework is applied to evaluate the landscape ecological security with three dimensions, the pressure of landscape change, the state of the landscape ecology system, and the human response to landscape change. Five indicators are selected for the analyses and spatially quantified, including the development intensity of construction land, population density, structure state, function state, and implementation degree of urban ecological function zoning [25,61]. Then, these indicators are divided into two types based on their effects on ecological security: positive factors (+) and negative factors (−).…”

Abstract:Urban ecological security is the basic principle of national ecological security. However, analyses of the spatial and temporal dynamics of ecological security remain limited, especially those that consider different scenarios of urban development. In this study, an integrated method is proposed that combines the Conversion of Land Use and its Effects (CLUE-S) model with the Pressure-State-Response (P-S-R) framework to assess landscape ecological security (LES) in Huangshan City, China under two scenarios. Our results suggest the following conclusions: (1) the spatial and temporal dynamics of ecological security are closely related to the urbanization process; (2) although the average values of landscape ecological security are similar under different scenarios, the areas of relatively high security levels vary considerably; and (3) spatial heterogeneity in ecological security exists between different districts and counties, and the city center and its vicinity may face relatively serious declines in ecological security in the future. Overall, the proposed method not only illustrates the spatio-temporal dynamics of landscape ecological security under different scenarios but also reveals the anthropogenic effects on ecosystems by differentiating between causes, effects, and human responses at the landscape scale. This information is of great significance to decision-makers for future urban planning and management.
