中文摘要：

在东方亚洲副热带的季风(EASTM ) 上的东方中国的城市的陆地使用变化的效果被使用社区空气模型版本调查 5.1。在城市的扩大和参考实验之间的结果的比较证明与城市的扩大，陆地表面精力平衡改变：当潜伏的热流动减少时，表面网放射和理智的热流动提高。作为结果，在东方中国上的表面空气温度的重要增加被检测。城市的陆地使用变化处于带的陆地海温度差别(LSTD ) 贡献一个变化，导致在 LSTD 变化从的时间的延期对积极否定，并且反过来也如此。另外， EASTM 的发作和撤退朋友也被耽搁。同时，在表面空气温度的上升导致反常在北方的空气流动的形成，它可以是原因为更慢向北方 EASTM 和它的北边界的一个更向南方的地点的运动。

英文摘要：

The effect of urban land-use change in eastern China on the East Asian subtropical monsoon（EASTM） is investigated by using the Community Atmosphere Model version 5.1.Comparison of the results between the urban expansion and reference experiments shows that with the urban expansion,the land surface energy balance alters：surface net radiation and sensible heat fluxes enhance while the latent heat fluxes reduce.As a result,a significant increase in surface air temperature over eastern China is detected.The urban land-use change contributes to a change in the zonal land-sea temperature difference（LSTD）,leading to a delay in the time when LSTD changes from positive to negative,and vice versa.Additionally,the onset and retreat dates of the EASTM are also delayed.Meanwhile,the rise in surface air temperature leads to formation of abnormal northerly air flows,which may be the reason for the slower northward movement of the EASTM and a more southward location of its northern boundary.
