Land planning method and system based on land allocation model

Abstract

The invention discloses a land planning method and system based on a land allocation model. The method comprises the implementation steps: obtaining the economic, social, land suitability, environment and ecological development cost information of a to-be-planned land; building the land allocation model which takes the development cost information as a constant, a land planning scheme as a variable and the economic benefit as a target value; carrying out the constraining of the land planning scheme through constraint conditions, and taking the land planning scheme corresponding to the maximum economic benefit as a final land planning scheme, wherein the constraint conditions comprise the economic constraint, the social constraint, the land suitability constraint, the environment constraint and the ecological constraint. According to the invention, the method achieves the constraining of the land allocation model through the constraint conditions, gives consideration to the inherent uncertainty, systematicness and complexity of the to-be-planned land, and achieves the complete land planning.

Description

technical field [0001] The invention belongs to the field of land planning, and more specifically relates to a land planning method and system based on a land allocation model. Background technique [0002] my country is going through a stage of social and economic transformation and development. With the acceleration of urbanization, industrialization, and modernization, extensive land use methods, excessive pursuit of economic benefits, and neglect of social and ecological benefits make the land use structure unreasonable, not only causing The massive waste of land resources has led to many social and environmental problems such as over-expansion of cities, loss of a large amount of agricultural land, and deterioration of the ecological environment, and has become the most serious bottleneck restricting sustainable development. [0003] In foreign countries, models have long been used to solve resource allocation problems. Since Gilbert et al. put forward the first mathema...

Problems solved by technology

Linear programming models and multi-objective models do not involve space optimization, and cannot deal with nonlinear, complex and uncertain land use optimal allocation problems

CLUE does not consider the ecological environment factors in the land system, nor does it consider the uncertain parameters of the land system caused by nature or thought.

[0005] There are two main defects in the traditional optimal allocation model of land use: one is the lack of comprehensiveness of the system

Previous models often only considered the relationship between the land system and economic benefits, or considered the relationship between the land system, the economic system, and the environmental system, ignoring ecological and social factors; second, the inherent uncertainty of the land system was often ignored
