基于协同学理论的宁波市土地利用结构协调性评价

Coordination Evaluation of Land Use Structure in Ningbo Based on Synergetics Theory

根据协同学相关原理,对土地利用结构进行协调性评价,通过构建土地利用系统,选取状态参量并建立序参量指标体系,在此基础上协调耦合度模型进行协调性评价。结果显示:(1)宁波市土地利用社会子系统发展指数远高于土地利用生态发展指数和土地利用经济发展指数,说明宁波市仍处于经济粗放的发展阶段。(2)宁波市土地利用系统在2005-2008年一直处于低水平的耦合协调状态,需要继续发展;在2010-2011年间,系统处于耦合协调颉颃状态,在2012-2014年间,系统处于良性耦合协调状态,逐渐从无序走向有序。

To realize cooperation management of land allocation in NingBo, we research in land allocation in NingBo from 2005 to 2015, and structure the land-use subsystem under the target of economic efficiency, social efficiency, ecological efficiency, build state parameter to use grey correlativity analysis with the information entropy of land use, select order parameter, cooperation analysis in development index in every subsystem, finally, evaluate the coupling coordination degree in land use system. The following conclusion can be drawn as： （1） The development degree in land-use social subsystem much higher than the development degree in land-use ecological subsystem and the development degree in land-use economic subsystem, It states that the economic development in NingBo still in the extensive development approach. （2） In 2005 to 2008, the land use system in NingBo always be at a low level in coupling coordination degree, It needs continually development; In 2008 to 2013 the system be antagonism in coupling coordination degree; In 2014 to 2015, the system be good coupling in coupling coordination degree, the system begin to move from disorder to order.
