Land suitability assessment for supporting transport planning based on carrying capacity and construction demand

Abstract

With the rapid global urbanization, the unlimited increasing transportation infrastructure has met the needs of urban expansion, but it has caused a series of ecological problems lacking consideration of ecological conservation. The land suitability assessment for supporting transport planning based on carrying capacity and demand for construction is an effective way to promote urban socioeconomic development and ecological conservation. Therefore, we constructed a logical framework of resources and environment supporting, traffic construction demand driving, and ecological protection red line and basic farmland constraining, and applied the analytic hierarchy process (AHP), GIS, three-dimensional magic cube method, and gravity model to evaluate the suitability of expressway development in Sichuan Province, China. The results showed that the spatial difference in the carrying capacity of resources and environment and the demand for expressway construction was relatively high in Sichuan, and those in eastern cities were even higher. The land suitability for supporting transport planning was relatively high, and the suitable areas with a grade from 8 to 10, accounted for 20.77% of the total study area, which could almost meet the demand for transportation infrastructure construction. The land suitability performed a circle structure with Chengdu as the core and gradually decreasing to the periphery. Overall, this study adds new insights to transport planning reform in other similar regions around the world and can provide important references for regional development planning and environmental protection.

Impact of Landuse Morphology on Urban Transportation

“…The same can be said of New layout where most residential houses are currently rehabilitated to serve the demand for better housing by teeming urban population and gentrification within the city centre. This result however contrast with the submission of Li et al, [48] who believed that the more significant the position of the core node, the more crucial it is to improve traffic conditions in the surrounding area to enable urban development. It is also worthy of note that city Planners are sometimes oblivious of the fact that the development and expansion of roads to improve ease of access or reduce congestion and increase traffic speed would promote increased use of automobile and invariably auto-dependency [12,49].…”

Research Progress of the Impacts of Comprehensive Transportation Network on Territorial Spatial Development and Protection

“…And the "three lines" correspond to the three control lines, namely, the urban development boundary, the permanent basic farmland, and the red line of ecological protection, which are delineated in the urban, agricultural, and ecological spaces, respectively. The conflicts and contradictions between transportation lines and ecological and agricultural land have gradually come to the forefront, and transportation facilities are facing increasingly serious development constraints [117]. In this regard, relevant scholars believe that the mechanism of permanent basic farmland occupation and deployment of transportation linear projects should be established, and the control rules for harmlessly crossing the red line of ecological protection should be adopted in time for the post-evaluation of environmental impacts and ecological restoration work [118].…”

Evaluation of the operation status of the residential land market in Beijing-Tianjin-Hebei region of China and its spatiotemporal pattern characteristics

“…Land resources are the carriers of social and economic activities, and the degree of their rational allocation is directly related to the urbanization process, sustainable economic development, and the improvement of people's livelihood [1]. As one of the countries with the fastest urban land expansion [2,3], China's real estate industry has become a pillar industry for economic growth and an important source of local fiscal revenue in all regions, but at the same time, the problems of land resource management and use are becoming increasingly prominent. For example, the expansion of urban construction is accompanied by the disorderly spread and waste of land, which has led to inefficient land use, soaring land prices, and environmental degradation [4][5][6].…”
