Research of Urban Suitable Ecological Land Based on the Minimum Cumulative Resistance Model: A Case Study from Hanoi, Vietnam

Abstract

Rapid urbanization process is accelerating the dramatic transformation of urban land use, creating strong economic, social and environmental impacts in Hanoi (Vietnam). Improving the quality and optimizing the model of using ecological land in urban areas is very important to solving environmental issues and sustainable urban development. Using the Hanoi capital of Vietnam, an important and typical city in the Red River Delta, as in the case of the study, we applied the Minimum cumulative resistance model (MCRM) to calculate ecological land and constructed land meet the needs of socio-economic development and ecological protection. Results showed that the suitable ecological land area is about 2.090,298km2 (ecological land area 1.112,216km2, ecotones land area 978,082km2), which is 62% of the total urban area of Hanoi is mainly distributed in Bavi, Socson, Unghoa, Myduc, Chuongmy districts and Sontay town; and constructed land area is about 1.275,736km2, which accounts for 38% mainly distributed in the city center and urban areas. Study the ecological land space and construction land of Hanoi area and compare with the current land use status through simulation of MCRM model, we propose three types of land use. For urban ecological land, there must be measures to manage and protect the ecological environment and prohibit construction activities in the area. For ecotones land between urban construction land and ecological land, it is necessary to control and limit the construction to improve the quality of the ecological environment. For construction land, there must be a policy to promote construction along with reasonable and efficient land use development to improve urban living environment.

Predicting Urban Waterlogging Risks by Regression Models and Internet Open-Data Sources

“…Currently, many areas in the core of Hanoi's inner city have very high population densities, which are areas that can be considered as slums with green spaces and technical infrastructures that are lower than the national standards [112]. We checked the population density data and location information of waterlogging spots and found that most of the waterlogging spots that occurred with high frequency were located in areas with high population densities ( Figure 3a).…”

“…Rapid urbanization is accelerating the transformation of urban land use, usually by reducing natural land and increasing the impervious surface areas, and is affecting the social economy and the environment in Hanoi [112]. Much research shows that an impervious surface is one of the most important factors for urban rainstorm waterlogging.…”

Assessment of the Susceptibility of Urban Flooding Using GIS with an Analytical Hierarchy Process in Hanoi, Vietnam

“…Rapid urbanization in Vietnam is exacerbating environmental issues in urban settings, which is compounded by the growing unpredictability of extreme weather events [37]. Hanoi, one of the largest and most densely populated cities in Vietnam, has witnessed increasingly intricate and challenging urban flooding in recent years [38,39]. There have been several studies utilizing various methods and approaches to urban flooding in Hanoi.…”

Comprehensive Land Consolidation Zoning Based on Minimum Cumulative Resistance Model—A Case Study of Chongqing, Southwest China

“…This approach can improve resource utilization efficiency and promote coordinated development between regions [32]. The minimum cumulative resistance (MCR) model has been widely utilized in landscape ecological security pattern analysis [33], suitability evaluation of building land [34], and other sectors to analyze the suitability of land expansion by generating resistance surfaces for various parameters within a region. The MCR model can simulate the process of mutual balance and constraint among PLES, achieving the comprehensive maximization of production, living, and ecological benefits.…”
