摘    要:本文通过对协调度、协调发展度进行理论辨析,分别建立了土地利用与生态环境子系统指标体系,运用基于土地利用综合评价函数和生态环境综合评价函数的协调发展度模型对天水市2005年-2007年的协调度进行了分析。研究结果为2005-2007年间天水市土地利用与生态环境的协调等级均为良好协调,但土地利用与生态环境子系统的协调发展类型属于良好协调发展类生态环境滞后型,天水市生态环境的建设与保护适度滞后于土地利用的发展;也说明基于土地利用综合评价函数、生态环境综合评价函数的协调发展度模型,能够实现土地利用与生态环境两系统间协调关系的定量评价,可信度较高,可操作性较强。

关 键 词:天水市  土地利用  生态环境  协调发展

Abstract:In this article, index system of the land use subsystem and ecological environment subsystem were set up respectively, though the analysis of definition on the coordination degree between land use and ecological environment. And the paper uses the mathematic model of the coordinated development which is based on the valuations of land use and environmental evaluation to evaluate development condition between land use and ecological environment in Tianshui from 2005 to 2007.The results show that Tianshui's coordination degree between land use and ecological environment is in the good coordination development class, but the type of coordinative development between land use and ecological environment belongs to lag-type of ecological environment, it means the ecological environment construction and protection lags behind the land use moderately in Tianshui, and that the computation model in this paper is a useful tool for evaluating the harmonious degree between land use and ecological environment with high operability and credibility.
Keywords:Tianshui city  land use  ecological environment  coordinated development degree
