Land use dynamic evolution simulation method and system for coping with sea-level rise

Abstract

The invention discloses a land use dynamic evolution simulation method and a land use dynamic evolution simulation system for coping with sea-level rise, which are used in the field of land use simulation and prediction in urban planning. The land use dynamic evolution simulation method comprises the steps of: constructing a comprehensive index of exposure degree, sensitivity and adaptability to identify vulnerability degrees of regions under the influence of sea-level rise; identifying land use suitability of the regions according to land use space physical attributes, space accessibility indexes, neighborhood attributes and socio-economic factors; and determining a future land use rule of each land use region according to the vulnerability degrees of regions and the land use suitabilityof the regions, wherein the future land use rule is described in that a target region of the optimal land use development space must satisfy the condition of having the highest land use suitability and the lowest vulnerability degree. The land use dynamic evolution simulation method and the land use dynamic evolution simulation system provide a direct scientific basis for the decision-making of coastal city space planning, enhance the rationality and scientificity of the planning scheme, and thus promotes the transformation of urban planning from traditional qualitative and empirical planningto quantitative and scientific planning.

Description

technical field [0001] The invention belongs to the field of land use simulation prediction in urban planning, and more specifically relates to a land use dynamic evolution simulation method and system for coping with sea level rise. Background technique [0002] Global climate change has gradually become a focus of human attention and research. The report of the Intergovernmental Panel on Climate Change (IPCC) of the United Nations shows that the global climate system has been experiencing significant changes characterized by global warming in the past century. Variety. Climate change mainly caused by the greenhouse effect will have a huge impact on coastal areas such as sea temperature rise, large-scale glacier melting, and sea level rise (Sea Level Rise, SLR). [0003] Sea level rise is a slow-onset natural disaster, which makes storm surge disasters occur more frequently in coastal areas, flood disasters intensify, and low-lying areas and coasts are more severely eroded...

Problems solved by technology

[0008] Aiming at the above defects or improvement needs of the prior art, the present invention provides a method and system for simulating the dynamic evolution of land use in response to sea level rise, thereby solving the inability to directly analyze the impact of sea level rise on future land development. Deriving land-use adaptation strategies for climate impacts, making it difficult to intuitively guide the technical issues of urban planning practices in coastal areas
