The effects of multiple spatial policies and their management will have a profound impact on urban growth. Therefore, a quantitative evaluation of the effects of multiple spatial policies is proposed. In addition, the effects of a single policy, overlapped policy and combined policy are quantitatively evaluated through this method. The findings are as follows: the dominant effect of a single polygon control (polygon –shape control, such as residential planning area) is significant. In the overlapped policy, the effect of polygon control is strengthened. For example, compared to the single residential planning area, the proportion of new residential construction land increased from 75% to 94.2% within the overlapped planning areas (such as residential planning area plus point-shape control subway station); in addition, its mixedness decreased from 0.372 to 0.215. The combination of different types of polygon policies will further strengthen the control effect of the dominant type, improving the mixedness and population agglomeration. Finally, from the perspective of sensitivity analysis, the validity and credibility of the evaluation is proved.

多种空间政策及其管理的影响将对城市发展产生深远影响。因此，提出了对多种空间政策效果的定量评估。此外，通过此方法可以定量评估单个策略，重叠策略和组合策略的效果。研究结果如下：单个多边形控件（多边形-形状控件，例如住宅规划区域）的主导作用是显着的。在重叠策略中，多边形控制的效果得到增强。例如，与单一的住宅规划区相比，在重叠的规划区内（例如住宅规划区加点形控制地铁站），新住宅建设用地的比例从75％增加到94.2％；此外，它的混合度从0.372降低到0.215。不同类型的多边形政策的结合将进一步加强对主导类型的控制效果，改善混合性和人口集聚。最后，从敏感性分析的角度证明了评估的有效性和可信性。
