摘　　要：为了测试丘的适用性，从 1982 ～ 2001 的在到在纵的范围峡区域(LRGR ) 上的降雨的 RegCM3 的对流参数计划， 5 月和夏天降雨与对流参数在 RegCM3 策划的不同的丘被模仿。与观察的对比模拟降雨的定量分析的结果显示对流参数计划有的那 Fritsch-Chappell 积云在 LRGR 上的 20 年的全部的 5 月降雨的最好的模拟能力，和对流参数计划拿的 Anthes-Kuo 丘的模拟能力第二个地方。对流参数计划有的 Anthes-Kuo 丘在 LRGR 上的 20 年的全部的夏天降雨的最好的模拟能力，和 Fritsch-Chappell 的模拟能力得到第二个地方。在 LRGR 上模仿的全部的降雨是不到观察的。模仿的结果内部在 LRGR 上的 5 月和夏天降雨的年度变化几乎与模仿 20 年的全部的降雨的一样。Anthes-Kuo 和对流参数策划的 Fritsch-Chappell 积云在 LRGR 上在 5 月和夏天使对流过程适应描述丘。To test the applicability of cumulus convective parameter schemes in RegCM3 to the rainfall over the Longitudinal Range-Gorge Region （LRGR）, the May and the summer rainfalls from 1982 to 2001 were simulated with different cumulus convective parameter schemes in RegCM3. The results of quantitative analysis contrasting simulation rainfall with observational one indicate that Fritsch-Chappell cumulus convective parameter scheme has the best simulation ability to the 20-year total May rainfall over LRGR, and the simulation ability of Anthes-Kuo cumulus convective parameter scheme takes the second place. Anthes-Kuo cumulus convective parameter scheme has the best simulation ability to the 20-year total summer rainfall over LRGR, and the simulation ability of Fritsch-Chappell gets the second place. The total rainfall simulated over LRGR is less than the observational one. The result of simulating interannual variation of May and summer rainfalls over LRGR is almost the same as that of simulating 20-year total rainfall. The Anthes-Kuo and the Fritsch-Chappell cumulus convective parameter schemes adapt to describing cumulus convective process in May and summer over LRGR.
