城市蔓延 成本—收益綜閤指數 治理模式
성시만연 성본—수익종합지수 치리모식
urban sprawl; composite index of the cost and benefit; governance mode
城市蔓延为城市发展提供了一定的空间,但也会带来土地非合理利用、城市污染等问题。对城市蔓延的成本、收益进行了理论分析并构建了评价指标体系,采用因子分析法对我国69个大中城市的蔓延成本与收益进行了定量测度,初步构建了城市蔓延的成本—收益综合指数,并按协调程度分为高、中、低、弱四类。研究发现,各城市的蔓延体现为成本、收益一致性和经济发展相关性,且城市间差距显著。在此基础上,尝试提出了基于我国不同类型城市蔓延的治理模式。

Urban sprawl not only provides some space for urban development, but also causes a series of negative effects, like non - rational use of land and contamination. This essay analyzes in detail the potential eost and benefit of urban sprawl, and tries to use the factor analysis method to measure the cost and benefit of urban sprawl. It displays the scores of 69 large and mediumsized cities intuitively. Subsequently, this essay constructs the composite index of the cost and benefit for urban sprawl, and divides 69 large and medium - sized cities into 4 classes including the high - coordination degree, medium - coordination degree, low -coordination degree and inferiorco- ordination degree. The result shows that cities which sprawl cost and benefit scores at the forefront are all economically developed regions, and each city＇s ranking is consistent. In the end, it proposes governance mode for differenttype urban sprawl.
