“…However, in the south‐east plain on the outskirts of Beijing, an increase in road density will lead to an elevated ecological risk. Research by Lin et al (2019) showed that in Sanming City, Fujian Province, where the forest coverage is the highest in China, an increase in road transportation kernel density will significantly increase the landscape ecological risk in the eastern region, while the impact will be insignificant in the western region because road transportation exerted greater impacts in the eastern region, which has more frequent human activity.…”

“…The studies by Mo et al (2017) and Lin et al (2019) concluded that the development of road transportation could reduce the regional ecological risks in some areas, or that the impact is not significant. This research supplements existing relevant research conclusions to some extent.…”

“…Karlson and Mörtberg (2015) established spatial models and discovered that the natural grassland and southern broadleaf woods in Sweden were more susceptible to road transportation development, while forests were impacted to a lesser extent. By establishing a geographically weighted regression model, Lin et al (2019) found that road transportation impacted the ecological environment of areas with more human activities to a greater extent, and areas with fewer human activities, such as forests, to a lesser extent. Liu et al (2008) used buffer analysis and scenario analysis to analyse the impact of the development of various types of road transportation on different landscapes and ecological risks in the Lancang River valley region.…”

“…Studies on the impact of road transportation development on the habitat in economically developed areas are rare. Compared with ecologically protected areas, the demand and supply of road transportation in economically developed areas are higher, and the development of road transportation may have a more severe impact on the ecological environment (Condurat et al, 2017; Kleinschroth & Healey, 2017; Lin et al, 2019; Liu et al, 2008; Wen et al, 2008).…”

The excessive expansion of road transportation often has an impact on the quality of regional habitats. This paper attempts to assess the impact of road transportation on regional habitat quality in economically developed areas. A kernel density analysis was used to characterise the road transportation development in Jiangsu Province from 2000 to 2015. An Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) habitat quality model was applied to assess changes in habitat quality. Furthermore, a fixed-effect regression model was utilised to examine the impact of road transportation development in Jiangsu Province on habitat quality. The analysis indicates that the average kernel density of road transportation in the province increased from 0.109 to 0.551 km/km 2 while the habitat quality decreased from 0.51 to 0.48. The development of road transportationin Jiangsu Province has had a serious negative impact on the quality of the habitat. For every 1-ha increase in land area for road use, the habitat quality index will decrease by 0.066; for every 1 km/km 2 increase in road transportation kernel density, the habitat quality index will decline by 0.121.

“…Among them, from the macro view point of the virtual pattern constitutes the road network of the urban space vein, the road itself is the spatial sequence and order influenced by the road alignment and architectural layout [33]. At present, the research on the virtual pattern of urban road landscape mainly focuses on the impact of road network construction on urban ecological landscape, such as the impact of road network expansion on the connectivity of ecological landscape [34][35][36], the impact on ecological risk of urban landscape [37], the impact on the urban ecological landscape pattern [38], the impact on the ecological diversity of agricultural landscapes [39] and so on.…”

Road Landscape Morphology of Valley City Blocks under the Concept of “Open Block”—Taking Lanzhou City as an Example

et al. 2019

The unique valley geographical environment and the congestion-prone road landscape make valley city traffic jammed easily. In this paper, under the background of “open blocks”, two open patterns, which correspond to two different road landscapes ("ideal grid opening" and "open under realistic conditions"), are proposed. Taking Lanzhou city as an example, six basic statistical characteristics are used to compare and analyze the changes of road network topology in blocks to find out which open pattern is more suitable for valley cities. The results show that the pattern "open under realistic conditions" has a significant effect on the improvement of network performance and capacity. Specifically, breaking the "large blocks" and developing the small-scale blocks help to alleviate the traffic pressure. Besides, the opening of blocks located along river valley has a more positive effect on improving road network performance than the blocks sited in the inner area of cities.

Evaluating the landscape ecological risk based on GIS: A case‐study in the Poyang Lake region of China

et al. 2021

Influenced by human activities, the largest freshwater lake in China, Poyang Lake is suffering from landscape degradation and increased ecological risks. However, the specific landscape ecological risk in Poyang Lake region remains unknown. The impact of land use change on landscape pattern and ecological risk around Poyang Lake has not been revealed. In order to analyze the spatio-temporal distribution characteristics of landscape ecological risk in Poyang Lake region, this study constructed a landscape ecological risk index model based on GIS, geostatistics, and landscape ecology theory. The results show that: (a) all land use types in Poyang Lake region had been changed during the period 2010-2018. While large tracts of farmland and woodland were converted into construction land, farmland and woodland have seen the largest decrease and construction land has increased greatly. (b) On the whole, the low and medium-low landscape ecological risk area accounted for about 60% of the total area, while high and medium-high risk area increased during 2010-2018. The landscape ecological risk has seen a downward trend with increased low and medium-low ecological risk areas during 2010-2018. Spatially, ecological risk in the core waters of Poyang Lake was higher, while in the surrounding waters was lower. (c) The landscape ecological risk in Poyang Lake Region in each period shown positive spatial correlation and tended to be spatially agglomerative. The high-high risk clusters were mainly located in the core waters of the Lake area, while the low-low risk clusters were mainly located far away from the core waters, including county and city areas. (d) In 2018, farmland, woodland, grassland, and unutilized land were dominated by medium and medium low risk, the landscape ecological risk in the water area was the highest, and that of construction land was the lowest. The decrease rate of ERI in water areas was the largest, indicating that the change of water area contributed the most to the reduction of landscape ecological risk. During the process of ecological risk management in Poyang Lake Region, attention should be paid to the changes of the water area's structure and quality.
