“…Notably, for this region, the composition is not only determined by land-use but also by other driving factors, such as biophysical factors, landscape structural characteristics, and human attributes (e.g., settlements) [28,40]. Several scholars have carried out quantitative analyses on landscape patterns from the perspective of land-use type [34,76,77]. Our study provides a new perspective for landscape structure analysis.…”

Landscape character assessment (LCA) is a widely used tool that integrates natural, cultural, and perceptual attributes to identify and portray landscape. In this study, we used the LCA method to identify the landscape characteristics of China at the national scale. Furthermore, we applied cultural and landscape structural factors along with spatial transmission to improve the identification system. First, we incorporated all the parameters in the assessment. We selected 15 landscape character factors from four factor types including nature, culture, spatial geographic co-ordinates, and landscape structure. These parameters were analysed using multilevel overlay and spatial connection tools in ArcGis 10.2, which resulted in 2307 landscape description units (LDUs). Second, the spatial structure properties of the LDUs were determined using a semivariogram and the moving window method in ArcGis 10.2 and Fragstats 4.2 software, respectively. Third, for visualisation, we applied the principal component analysis (PCA) using the SPSS software and elbow and k-means clustering methods using MATLAB to determine 110 landscape character types (LCTs) of China’s entire terrestrial landscape. Finally, we determined 1483 landscape character areas through semiautomatic segmentation and manual visual correction using eCognition. Based on the unique characteristics of the entire terrestrial landscape of China, a set of ideas and methods for the overall identification of LCTs was proposed. Our findings can be used to optimise territorial spatial planning and landscape protection and management, and promote multiscale land-use studies in China.

“…Furthermore, urban sprawl indirectly affects economic mobility and exacerbates income segregation [27,28]. As for ecological consequences, though urban areas occupied small fraction of land as compared to other land use types, their impact on ecosystems is significant [29]. Dupras et al [30] propose that the dispersed sprawl of low-density urban areas within a territory sharply increases the fragmentation of the territory, thereby isolating the few remaining natural spaces and decreasing their ecological connectivity and biodiversity.…”

Identifying the effects of urban sprawl on urban development is of strategic importance. This study takes 285 prefecture-level and above cities in China as research samples and empirically analyzes the heterogeneous impact of urban sprawl on economic development from 2009 to 2018. Results indicate the threshold effect of urban sprawl on economic development. That is, moderate urban sprawl has a significantly positive influence on economic development, whereas excessive urban sprawl has a significantly negative impact on economic development. The empirical analysis also identifies heterogeneities in the effects of urban sprawl on economic development. Compared with the sprawls of small- and medium-sized cities, those of large cities have a greater negative impact on economic development. Compared with the sprawls of cities dominated by the tertiary industry, those of cities dominated by the secondary industry have a greater negative impact on economic development. Findings of this study have important policy implications for scientific urban expansion, reasonable urban spatial layout, and sustainable urban economic development.

“…In terms of the decision‐making process, the importance of landscape planning will be to best allocate what activities should be developed with the remaining available land (i.e., between agriculture, urbanization, and industrial activities). This process is vital for the sustainable development of Markazi Province (Getu & Bhat, 2021; Guan, He, He, Cheng, & Qu, 2020) and aids in facilitating sound decision‐making for future generations. To help with this effort, a suitability analysis for urban growth is considered to identify the best urban growth locations (Biney & Boakye, 2021; Lan, Zheng, & Li, 2021).…”

Markazi Province has high potential for residential development due to its geopolitical location in the central part of Iran. This study investigated the possibility of residential area development in Markazi Province using a GIS‐based analytic network process. ArcGIS Version 10.6.1 and Super Decision Version 3.2 software were utilized for the zoning and assessment of criteria. All criteria, and their sub‐criteria, and limitations were gathered using national standards, literature review, and experts. According to the final residential area land suitability map, 16.74% of Markazi Province is highly or very highly suitable for urban development, even though 57.55% of the province's area (i.e., 30% of its current cities) are located in the exclusion zone. Results suggested that most parts of the province do not have desirable conditions for residential zoning. Further attention and deepened GIS monitoring over an extended period would be beneficial before future development is considered. In particular, the natural limitations in the region—such as slope—impede development potential. The study provides an alternative quantifiable and verifiable approach for sustainable urban planning from a land use policy perspective.
