长江经济带上游地区丘陵城市工程建设适宜性评价——以泸州市规划中心城区为例

以长江经济带上游地区泸州市规划中心城区为例，建立了包括多因素综合评价模型和多层次评价指标体系的工程建设适宜性评价方法，采用模糊赋权法和层次分析法相结合的组合赋权法计算评价指标的权重，利用GIS空间分析技术对泸州市规划中心城区工程建设适宜性进行了评价，并对评价方法的可靠性进行了分析。结果表明：泸州市规划中心城区工程建设适宜性整体较好，以适宜、较适宜为主，其中适宜区、较适宜区分别占研究区总面积的36.16%、28.81%，此外适宜性差区、不适宜区各占20.96%、8.07%；泸州市城市规划建设、重大工程建设选址应在适宜区和较适宜区范围内，尽量避免适宜性差和不适宜地区；在适宜性差和不适宜地区进行工程建设应注意不同区段现有和可能诱发的地质灾害、地基不均匀沉降、软土、坍岸等问题的防治。建立的评价方法在丘陵城市工程建设适宜性评价上适用性较好。

Building Suitability Evaluation of Hilly City in Upper Reaches of Yangtze River Economic Belt: In Case Study of Urban Central Planning of Luzhou City

Taking the planning of the central urban area in Luzhou City as the research area, we firstly established the building suitability evaluation method, which includes multiple factors, comprehensive evaluation model, and multi hierarchy evaluation index system, secondly calculated the weight of evaluation factors based on Fuzzy weighting and APH, and then evaluated the building suitability of the research area combined with the statistical methods and GIS spatial analysis techniques, finally analyzed the reliability of the evaluation methods. The results indicate that the evaluation method is suitable for hilly urban building suitability evaluation. The suitable area accounts for 36.16% of the total area, the relatively suitable area accounts for 28.81%, the poor area accounts for 20.96%, and the unsuitable area accounts for 8.07%. The building suitability of the research area is well. The planning and construction and the site selection of major construction in Luzhou City should be in the suitable area or relatively suitable area. If the construction and major construction site is in a poor area and unsuitable area, the attention should be paid to the prevention and control of the existing and possible geological disasters induced by uneven settlement of foundations, soft soil, and collapse in different sections.
