土地利用效益的耦合模型及其应用
Coupling model of land use benefits and its application
【摘要】 在分析土地利用社会经济效益与生态环境效益相互关系的基础上,借助于系统科学理论建立起土地利用社会经济效益与生态环境效益之间的耦合模型,用耦合度来表达这两种效益之间的协调关系与程度.土地利用效益之间的耦合关系为一椭圆轨迹,系统演化经历低级共生、协调发展、极限发展、再生发展4个阶段.以广州市为例,对沿海地区土地利用效益之间的耦合规律进行实证研究.结果表明:1990—2005年期间,广州市土地利用社会经济效益处于持续上升状态,而生态环境效益波动较大,最近几年处于上升状态.在此期间,广州市土地利用效益的耦合度表现为一条抛物线,总体处于协调发展阶段.1994年以前,耦合度处于下降状态,1994年以后,耦合度处于上升状态.上世纪90年代中后期土地利用效益处于最佳耦合状态,最近几年耦合程度有所下降.
【Abstract】 Through analyzing the interaction between socio-economic benefits and eco-environment benefits of land use, a dynamic coupling model between land use benefits was set up according to the theory and method of system science. Coupling degree was used to express coordinated relationship of land use benefits. The model revealed that land use benefits systems went through 4 stages, e.g. low-grade symbiosis,coordination development,limit development and revival. The model was successfully applied in studying the coordinated relationship of land use benefits in Guangzhou City. The socio-economic benefits and eco-environment benefits of land use were better and better during the period of 1990-2005. The former rises stably and the later develops fluctuation. In general, the coupling degree evolvement of land use benefits in Guangzhou City was a parabola in the 16 years and demonstrated coordinated development. The coupling degree decreased in the earlier 5 years and increased in the later 11 years. In the middle-later of 1990’s, land use benefits were the best coordinated.
