Description

A kind of urban land increment Index, server and system
Technical field
The invention belongs to land use planning field, more particularly to a kind of urban land increment Index, service Device and system.
Background technology
Since 21 century, China enters the High-speed Urbanization stage, and Urban Land Expansion is urbanization in space One of upper performance feature the most obvious.As urban population increase and economic development, Urban Land Expansion are inevitable development Trend, but there is also the land resource waste problem that urban land blind expansion is brought simultaneously.The too fast expansion of urban land Cause large stretch of good farmland to disappear, with being also further exacerbated by people contradiction, in this context, the research about Urban Land Expansion increasingly by To attention.In terms of Urban Land Expansion feature and driving force research, by Multivariate, Urban Land Expansion is studied Speed and amplitude；Based on satellite image and statistics, space characteristics, spatial model and the driving of Urban Land Expansion are analyzed Power；Research shows, influence the principal element of Urban Land Expansion include Economic Developing Standard of Cities, the level of urbanization, policy because Plain and macroscopical regional conditions, and Economic Developing Standard of Cities is relatively large on land scale change influence.The country is to city at present The research that city's land sprawl influences is directed to city self-growth mainly from cultivated land protection, ecological environmental protection angle Influence research it is less.In terms of Urban Land Expansion controls research, it is proposed that a series of to be related to the side such as economy, law, administration The Urban Land Expansion control measure in face, are such as directed to the unordered extension of Elements of Urban Land Scale, and the grand propositions of Qu Yu are sharp to improve soil With the policy braking measure that efficiency is guiding；Ma little Jun uses threshold analysis, from resource restriction angle, determines that urban land closes Reason scale, and then propose Elements of Urban Land Scale control measure.
The research of Urban Land Expansion at present is concentrated mainly on enlarging property, driving force, control measure etc., and city Land sprawl control measure also use Qualitative research method mostly, propose the policy control measure such as law, economy, administration, lack Weary Quantitative research method.China's cultivated land resource is in short supply, when formulating overall plan for land use, carries out top-down city and uses Ground increases control policy, how to increase urban land and is combined with urban construction and development, and is utilized according to city existing land Actual effect, to city incremental land supply propose restrictive condition, reasonable distribution city increase newly land use index it is particularly important.
The content of the invention
