Multi-Scenario Simulation of Land Use and Landscape Ecological Risk Response Based on Planning Control

Abstract

This study applied territorial spatial planning control to a land use multi-scenario simulation in Changde, China, and measured the landscape ecological risk response. It embedded five planning control schemes, respectively, involving inertial development, urban expansion size quantity control, ecological spatial structure control, land use zoning control, and comprehensive control. Findings show that: (1) Woodland and arable land in Changde occupy 31.10% and 43.35% of land use, respectively, and constitute the main functional space of the research area. The scale of construction land in Changde has enlarged continuously, with ecological space represented by woodland and water constantly squeezed and occupied. (2) Comprehensive control has the most remarkable restraining effect on the disordered spread of construction land, while ecological space structure control is the most effective way to control ecological land shrinkage. (3) The overall landscape ecological risk index expanded over 2009–2018, presenting an S-type time evolution curve of “sharp increase–mitigation”. Landscape ecological risk presents a single-core, double-layer circle structure with the north and east regions as the core, attenuating to the periphery. (4) Landscape ecological risk under land use zoning control increased significantly more than in other scenarios. Comprehensive control best prevented landscape ecological risk and restrained the disorderly expansion of construction land.

A Simulation of the Spatial Expansion Process of Shrinking Cities Based on the Concept of Smart Shrinkage: A Case Study of the City of Baishan

“…In view of this, Baishan, a representative shrinking city in Northeastern China, is taken as a case study in this paper, and the coupled patch-generating land use simulation-system dynamics (PLUS-SD) model is utilized, which can give full play to the spatial expression advantages of the PLUS model and the complex system simulation of the SD model. In addition, this study constructs three development scenarios for the future development plan of Baishan: natural growth, traditional planning, and smart shrinkage [21,22]. Subsequently, the feasibility of implementing the concept of smart shrinkage planning in China's shrinking cities is explored by comparing the characteristics of the spatial pattern and the differences in the utilization efficiency of construction land in Baishan under three different development scenarios (Figure 1).…”

Pathways to enhance the efficiency of forestry ecological conservation and restoration: empirical evidence from Heilongjiang Province, China

“…China proposed integrated restoration of mountain-river-forest-farmlandlake-grassland (MRFFLG) ecosystems in 2013 as an innovative approach to advancing territorial space protection using a systemic and holistic approach (Gao et al, 2022). It requires beginning by optimizing territorial space layout, adjusting land use structure and relationships, and conducting overall protection, systematic restoration, and comprehensive governance in accordance with the integrity, systematicity, and regularity of the ecosystem (Wang et al, 2022). China has implemented three batches (25 in total) of pilot projects since 2016 for the conservation and restoration of MRFFLG, which cover the majority of Chinese provinces (autonomous regions and municipalities).…”

City Health Examination and Evaluation of Territory Spatial Planning for SDG11 in China: A Case Study of Xining City in Qinghai Province

“…Whether cities are healthy and sustainable has an important impact on the improvement of human well-being and high-quality social and economic development [ 1 , 4 ]. Sustainable cities are the focus of many disciplines [ 5 , 6 ].Thus, territorial spatial planning control is important to optimize the interaction between the natural environment and land use and to resolve the conflict between social and economic development and ecological protection [ 7 ]. In 2015, member states of the United Nations committed to implementing 17 Sustainable Development Goals (SDGs) as part of the 2030 Agenda for Sustainable Development, and Sustainable Cities and Communities (SDG11) is central to achieving all SDGs [ 8 , 9 , 10 , 11 ].…”
