摘要

摘要: 采用主成分分析法并结合SPSS，对1999-2013年重庆市土地持续利用与生态环境的耦合关系进行分析，研究结果表明:1999-2013年土地持续利用指数逐年递增，土地开发利用强度逐年不断加大，城镇化大规模的建设是土地利用强度升高的主要原因；生态环境质量除了在2000-2004年生态环境指数呈“V”字型发展之外，总体呈上升态势发展；重庆市土地持续利用与生态环境耦合发展度由0.387 4（轻度失调衰退土地利用损益型）上升至0.754 0（中级协调发展经济主导型），但2011年情况有所变化，土地持续利用指数首次低于生态环境指数，耦合发展基本类型由生态主导型转向经济主导型发展，经济发展方式由土地利用制约型演变为生态环境制约型，生态环境效益滞后于土地资源经济效益。土地资源总体利用水平提高和生态环境改善的双重作用是耦合关系由失调发展转化为协调发展的主要原因。现阶段应坚持土地资源集约利用与保护并举，优化经济结构与技术创新齐下，发展循环经济和清洁能源，维系相对稳定的生态环境运行机制，确保重庆市土地资源可持续利用。

Abstract: A rational assessment of the coupling relationship between land use and ecological environment is the premise to ensure that the land resources can be sustainably utilized for the economic development in a region. Chongqing is partially situated in karst area with a vulnerable eco-environment where in the past the environmental impact due to unchanging land use pattern has been severe. Therefore, a well coupled relationship between land use and eco-environment is very important for the sustainable development in the area. In this paper, this relationship and associated reasons for various coupling are fully analyzed, by using principal component analysis through the application of statistical software SPSS. The results show that, land use index increased year by year from 1999 to 2013, which was attribute to the large-scale construction of urbanization. In the same period, the ecological environment index show that the overall eco-environmental quality in the area had a steady increase, except for a declined state from 2000 to 2004. The results also show that, coupling development degree has risen from 0.3874 which implies a mild recession and loss of the land use type, to 0.7540 which suggests an intermediate coordinated development and economic domination type from 1999 to 2013. However, the situation was changed in 2011 when the land use index was for the first time less than the ecological environment index. As a result, basic types of the coupling development was shifted from an ecology-oriented development to an economy-dominated one; the mode of regional economic development changed from a land use controlled type to an eco-environment constrained one; and the ecological environment benefit lagged behind the economic benefits from the use of land resources. Due to the improvement of overall land resource utilization level and ecological environment, the coupling relationship has been transformed from the imbalance development into coordinated one. At present stage, we should stick to such an idea that both intensive utilization of land resources and immediate measures for the resource protection should be implemented simultaneously. Meanwhile, it is encouraged to optimize the economic structure and innovative technology, to develop cycling economy and clean energy, and to maintain a relatively stable eco-environment dynamics to ensure that the utilization of land resources in Chongqing can be sustainably implemented.
