利用纵向岭谷区北回归线沿线及南北两侧的24 个站点1961-2007 时段月降水资料，基于全部站点的年降水主要特征统计，以及北回归线沿线的9 个站点的年降水变化的趋势性和阶段性检验、9 个站点间的年降水和5-10 月各月降水序列的相关性检验，分析研究区的年降水及变化分异特征。结果表明：研究区年降水主要特征及其年际变化，呈现出西部、中部、东部的空间分异，即三个区域各自内部自相似度高，而三个区域之间分异明显。北回归线沿线9 个站点的年降水序列都未表现出明显的“突变趋势性—阶段性”变化。研究区中部“岭—谷”相间的地形格局，对中部区域降水空间分异产生一定的影响，但相邻站点间多年际降水序列呈高度相关，意味着控制中部区域降水的决定性因素并不存在明显分异，间隔分布的“岭—谷”地形会带来局地性降水量的分异。

Through using monthly precipitation data of 24 meteorological stations near the Tropic of Cancer in southern Longitudinal Range-Gorge Region (LRGR) covering the period 1961-2007, this study first analyzed the main characteristics of annual precipitation at each station. Secondly, it tested the changing trend and phases of annual precipitation at 9 stations along the Tropic of Caner in the study area. Then it calculated the correlation coefficients of annual precipitation series and monthly (May to October) precipitation series between stations along the Tropic of Cancer. The results showed that in the study area, annual precipitation and its inter-annual changes are characterized by certain regional variations. On this basis, three zones are identified, i.e., western part, central part and eastern part. High similarity was found in each of the three parts and obvious variation was observed among them. Annual precipitation series at each station along the Tropic of Cancer within the study area did not present obvious “abrupt trends-phases” changes. Range-gorge landforms within the central part of the study area have certain influences upon the spatial variation of precipitation, while high correlation coefficients of annual and monthly precipitation occurred between the neighbouring stations, especially on the two sides of the Ailao Mountain within the central part, indicating that there were no obvious differences for the precipitation-driving factors in the central part. Regional inter-distributed range-gorge landforms are likely to cause local variations of precipitation.
