“…The usual approach is to further divide the planning control range based on constructing a landscape ecological security pattern to achieve urban spatial planning (Yu et al, 2005). The theory argues that landscape ecological safety patterns are equivalent to the ecological infrastructure of cities, an essential guarantee for continuous natural services for cities and residents and an unbreakable and rigid limit to urban expansion and land development and use (Machado et al, 2019). With the increasing importance of land ecological security, simulating the pattern of land‐use change under different scenarios based on the ‘anti‐planning’ theory has become a hot topic in recent years (Baldini et al, 2022; Li et al, 2021) because this mode can protect ecological red line zones in advance and provide decision makers with a variety of land‐use planning options.…”

Poor land use remains a major threat to ecological security. Land ecological security early warning and simulation of land‐use patterns based on the ‘anti‐planning’ theory provide many research bases for maintaining land ecological security. However, their utility with respect to illegal development and construction is limited. This study defines the concept of early warning based regional land‐use ecological security and builds a framework system for it. A case‐study investigation was carried out using land use, natural geography and social and economic basic data in Xingguo County, Jiangxi Province, China. The ecological red line zone (a sustainable ecological infrastructure for regional development similar to the municipal infrastructure) of the case area was 1816.16 km2, accounting for 56.49% of the total area; the core zone was 138.23 km2, accounting for 4.30% of the total area. For the natural development scenario, regional construction land pattern changes spread from the centre to the surroundings. In early warning land‐use ecological security, serious alerts were more concentrated in Lianjiang Town, Changgang Township, and Butou Township; moderate alerts were less concentrated and distributed in Longping Township and light alerts were more scattered and distributed in many townships. We propose corresponding prevention strategies for different levels of alerts. The construction of an early warning mechanism for regional land‐use ecological security can assist land spatial planning in regional development. More importantly, it can formulate land‐use ecological risk prevention strategies in advance.

“…The recommendation is that reforestation actions must be implemented in these areas, aiming at the environmental conservation of these fragile areas and at the landscape composition that can enhance other areas with greater ecotourism potential. Several authors demonstrate the effectiveness of reforestation in combating various environmental problems, such as [74][75][76][77], reinforcing the importance of forest restoration for local ecosystem services.…”

In recent decades, with the increasing global need for sustainable development, ecotourism has emerged as one of the most efficient activities that can be used to reconcile economic development with environmental conservation. A growing interest in the ecotourism and ecosystem services provided by landscapes makes such services increasingly necessary within municipal planning processes. This study aims to construct a geoenvironmental model based on geographic information systems (GISs) to spatially identify areas with greater capacity to promote ecotourism, with a practical case study of the city of Brotas, Brazil. The model can produce an integrated analysis of landscape components using geoenvironmental, topographic, and urban data. As a result, four zones were classified according to their ecotourism potential, with 81% of the overall local territory showing great potential, which not only reinforces the territory’s resilience regarding sustainable development, but also demonstrates that ecotourism should be included in discussions related to environmental planning in Brotas, as well as in other municipalities that have ecotourism potential.

“…Moreover, the state of the urban surface significantly influences the infiltration process of runoff, which can notably buffer surface runoff. For instance, the presence of extensive wetlands within a city can considerably enhance the city's resilience to disasters (Machado et al 2019;Zellner et al 2016). Despite significant advancements in surface-channel coupled models, an integrated model that accounts for the influence of flow depth in drainage networks on urban flooding remains elusive.…”

Effective urban land-use re-planning and the strategic arrangement of drainage pipe networks can significantly enhance a city's capacity to mitigate flood risks. Aimed at reducing the potential risks of urban flooding, this paper presents a straightforward and efficient approach to make urban land-use re-planning and drainage pipe network layout (ULP-DPNL). To achieve this goal, an urban distributed runoff model (UDRM) is firstly developed to quantify the discharge and water depth within urban drainage pipe networks under varying rainfall intensities and land-use scenarios. The Nash efficiency coefficient of UDRM is greater than 0.9 with high computational efficiency, affirming its potential benefit in predicting urban flooding. Then five different flood recurrence intervals are adopted to predict drainage congestion under both current and re-planned land-use typologies. The findings reveal that the re-planned land-use strategies could effectively diminish flood risk upstream of the drainage pipe network across all five flood recurrence intervals. However, in the case of extreme rainfall events (a 100-year flood recurrence), the re-planned land-use approach fell short of fulfilling the requirements necessary for flood disaster mitigation. In these instances, the adoption of larger-diameter drainage pipes becomes an essential requisite to satisfy drainage needs. Accordingly, the proposed UDRM-based ULP-DPNL approach effectively amalgamates land-use information with pipeline data to provide constructive recommendations for pipeline modification and land-use optimization in combating urban floods. Therefore, this methodology warrants further promotion in the field of urban re-planning.
