【摘要】 城市人居环境的创造和改善，既是一个古老的命题，也是一个与人类共存的永恒主题。随着工业化、城市化的发展，社会生产力不断提高，工业和人口的大规模集聚，改善城市人居环境，已经成为人类社会发展进程中的突出问题，必然引起了全人类的重视。 作为西部城市，兰州特殊的自然环境和相对落后的社会经济条件，导致了城市人居环境建设的相对滞后。为了全面评价兰州的人居环境，论文从组成城市人居环境的自然子系统、建筑子系统、支撑子系统和社会子系统等方面，以人居环境理论、可持续发展理论、城市生态学及生态经济等理论为指导，通过建立数学模型，构建了能够充分反映兰州城市人居环境的评价指标体系，该体系由四大子系统、11个次子系统和33个具体评价因子组成。利用兰州市区过去1990—2002年城市建设等方面的统计数据，对13年兰州城市人居环境建设质量，在时间序列上进行了趋势评价，并得出了以下一些主要的结论： (1) 兰州城市人居环境建设质量正向着高级化的方向演替。自然子系统、建筑子系统、支撑子系统和社会子系统的发展严重的不协调，四大子系统平均提升速度表现为：支撑子系统＞社会子系统＞建筑子系统＞自然子系统。 (2) 结合兰州城市人居环境建设的实际，根据综合建设质量走势图与自然子系统建设走势图的波动周期较为吻合特点，得出了影响兰州城市人居环境的主要因素是自然子系统的结论。 (3) 11个次子系统中，经济水平提升速度高于其余各次子系统，综合建设水平、自然子系统都严重滞后于经济水平，反映了一味地追求GDP的增长，而忽视城市人居环境的综合建设的问题。本文认为，建设“以人为本”、“实现经济与城市人居环境良性互动”应成为兰州城市人居环境建设的指导思想。 通过对综合建设质量、四大子系统、次子系统以及具体因子的态势分析，深入探讨了兰州城市人居环境建设优化的具体策略和途径。更多还原

【Abstract】 To construct and improve urban human settlements is not only an old proposition, but also an eternal subject that coexisted with human being. With the development of industrialization and urbanization and the increasing improvement of social productivity, industry and population have been centralized so intensively that more and more people in the world pay more attention to the improvement of the urban human settlements, which have become important problems in the development of the society.Lanzhou is one of the west cities in china, and the level of its urban human settlements is more laagered than other cities because of its special environment and relative poor social economic conditions. Under the guidance of theories such as the theory of human settlements, the theory of sustainable development, the theory of urban ecology and the theory of ecological economics, the dissertation sets up mathematic model and chooses a suitable index system, which is composed of 4 subsystems and 11 hypo-subsystems and 33 assessment elements, to assess the situation of the urban human settlements of Lanzhou in four aspects, including the nature subsystem, the construction subsystem, the supporting subsystem and the society subsystem. Based on the urban construction Statistic data of Lanzhou from 1990 to 2002,the dissertation assesses the quality of its urban human settlements in past 13 years and the developing trend according as time sequence. As a result, the dissertation draws the main conclusions as following.(1) As a whole, the qualities of the urban human settlements construction in Lanzhou becomes better than ever, but the development of the nature subsystem, the construction subsystem, the supporting subsystem and the society subsystem are not in harmony, and the average advance speed of the four subsystems can be described that the supporting subsystem is quicker than the society subsystem, the society subsystem is quicker than construction subsystem and the construction subsystem is quicker than the nature subsystem.(2) Based on the real condition of urban human settlements construction in Lanzhou, the dissertation draws a conclusion that the main factors which influence the urban human settlements in Lanzhou is natural subsystem, According to the identical characteristic of the trend of the natural subsystem and the urban synthesis construction quality.(3) In the 11 hypo-subsystems, the developing speed of the economic level is higher than the others, and the urban synthesis construction level and the developing level of the naturesubsystem are lower than the level of economy, which reflect that people attach great importance to pursue the GDP growth in the past, but ignore the synthesis development of the urban human settlements. So the dissertation considers that the principle of human-oriented and harmonious interaction of urban human settlements between the development of the economy and the urban human settlements should be regarded as the guidance of the urban human settlements construction.After analyzing the state of the synthesis construction quality, the four subsystems, the hypo-subsystems and the assessment elements, the dissertation probes into the main strategies and the approaches of the optimization of the urban human settlements construction in Lanzhou.更多还原
