摘要
根据环境经济学理论及一般系统论,建立土地利用效益的耦合模型;以西安市为例,探讨土地利用社会经济效益与生态环境效益之间的关系。结果表明,1992-2008年西安市土地利用效益耦合度的走势是先升后降,呈抛物线变化,并且介于14.13°~81.84°之间。1992-1994年,土地利用社会经济效益与生态环境效益的关系从不太协调向最佳协调状态发展;1995-2003年,土地利用效益的耦合度在较高水平上缓慢增加,社会经济与生态环境的胁迫与限制作用开始显现;2004-2008年,土地利用社会经济效益与生态环境效益之间的关系向着更协调的方向发展,在此基础上提出了优化西安市土地利用的几点建议。
Based on the environmental economics theory and general system theory,the coupling model of land use benefits is established.This paper,taking Xi＇an city as an example,discusses the relationship between socio-economic benefit and eco-environmental benefit of land use.The results show that the trend of coupling degree of land use benefits first rose and then came down in Xi＇an from 1992 to 2008.The above trend changes like a parabola between 14.13° and 81.84°.The socio-economic benefit and eco-environmental benefit of land use developed from the state of less coordination to optimal coordination from 1992 to 1994.The coupling degree of land use benefits slowly increased at a higher level,the coercion and restricted effect between socio-economy and eco-environment appeared from 1995 to 2003.The relationship between socio-economic benefit and eco-environmental benefit of land use developed in a more coordinated direction from 2004 to 2008.In general,the socio-economic benefit and eco-environmental benefit of land use keep on developing in a coordinated way in Xi＇an city.
