The paper analyses the law of services spatial diffusion in chongqing city , which is the law of business services spatial diffusion base on contagious diffusion hierarchical diffusion and base on the law of stochastic diffusion along the axes , and , according these principle , revise the unit factors score of business services calculated by using traditional way 由于重慶市地形復雜,江河阻隔,因此山城城市職能除表現為傳染擴散規律外,更突出地表現為等級擴散和軸向隨機擴散規律。文章依據這些原理對采用傳統的方法得到的商服功能影響作用分進行修正,同時探討了結點數動態變化時城市職能的空間擴散規律。

Meanwhile , an artificial imitation rainfall system was developed in order to study the characteristics of city underlying surface and make experimental check up about the relative appraising index , on which 200 rainfall experiments are made , analyzing the effect of rainfall intensity to the runoff of underlying surface ; the relationship between runoff permeability and unit factor of rainfall intensity and duration ; the effect of rainfall intensity , duration , soil moisture content , and temperature to the runoff permeability ; the relationship between rainfall quantity and runoff permeability , and make mathematical imitation to the expe rimental results , to find the mutual - relationships , and make discussion about the differences between equations of fit 同時,為研究城市下墊面的產匯流特性研制了一套人工模擬降雨系統,并對相關評價指標進行了實測校驗。在此基礎上,進行了200多場降雨實驗,分析了雨強、歷時、土壤前期含水量、溫度、降雨量、不同下墊面和不同覆蓋度等對產匯流的影響,及各種因素對徑流系數的影響和相關性,建立了一定條件下歷時徑流系數,雨強徑流系數,流量徑流系數的函數模型。

There are a lot of shortages by employing traditional ways to calculat ? unit factors score during land grading in mountain city , which stem from that we did not realize the law of services spatial diffusion in mountain city 在山地城市土地定級中,采用傳統的方法計算因素分值往往存在諸多問題,其原因在于沒有很好的揭示山城城市職能的空間擴散規律。
