The wavelet variance verification also indicates that the first main period of the runoff of mountainous watershed in the Shiyang River Basin is 30years, and 22years and l5years are the second and third period respectively; 3 Then we also compared the total runoff of mountain watershed with climate factors of Wushaoling which station is in the mountain headstream area, such as precipitation and temperature, the data record that the correlation coefficient of annual runoff and precipitation variation over the upper reaches in the Shiyang River Basin is 0.61 ,which indicates precipitation is the main water recharge of the runoff.

石羊河流域出山口年径流的周期变化与乌鞘岭站年降水量和年均气温周期基本上都能在同一周期上下浮动，其中出山口年径流量与乌鞘岭山区年降水量相关系数为0.61，说明地表径流量主要是由山区降水补给；年径流量与山区年均气温变化呈0.28的反相关，说明该流域近50年来出山口径流与山区气温呈反比，即径流量随年均气温上升而减少，相关性暂时不十分明显。

70年代，我刚进城工作，单位分配给我的宿舍就在西塘河边，尽管很小，可我推开东窗，面临的就是西塘河，那时的西塘河河面上，有南来北往经商的货船，有定时定班的客船，有张网收卡的小渔船，有做着小本生意的铜匠船，也有以船为家的住户船，河里有木排、竹排，白天船只来往穿梭，喧闹吵杂。

The evolvement of Diffluence River is the more complicated than Single River, because the diversion"s thing is changed with channel"s distortion. The river diversion is the general reflection of a good many factors, which mutually influence and adjust. In particular, when main channel occurs scouring-silting change, which causes the movement of water, sediment, and river bed in river system, the diversion will more be changed, with the study on division of discharge and sediment been further into, some practical engineering problem are solved.

目前，在对河道分流的认识与治理开发上虽取得了不少成绩，但随着社会经济的发展，人们对分流河道演变规律的认识与治理要求越来越高，随着人类对河流改造活动的加剧，河道的水沙条件可能发生急剧的改变，这些变化有可能使分流分沙的缓慢变化加剧，甚至改变原来的分流规律，许多研究者对分流分沙进行了较深入的研究，并能较好地解决了工程实际问题。

The present situation in flood-control and waterlog-drain are analyzed, and the present problems are pointed out.2 The causes and characteristics of the floods in Linyi are summarized, and the flood-control project and the waterlog-drain system in Linyi are also introduced.3 On the basis of summarizing the reconnaissance data of engineering geology, the engineering geology conditions of flood-control projects in the city of Linyi are studied, including the floodway project ,the hinge project, the Ge-Jiu Road Bridge project, the No.327 national highway road bridge project, the E-Huang Road Bridge project, and the Xiaogezhuang's chief inverted siphon project in the project of "Bifurcating the Su River to the Beng River".4 Seepage FEM analyses are carried out on the flood-control projects of Yi River, Beng River and Xiaosu River, respectively.

The results show that when the tropical western Pacific is in a warming state in spring, convective activities are intensified around the Philippines. In this case, there is a cyclonic anomaly circulation in the lower troposphere over the South China Sea, and the western Pacific subtropical high shifts eastward, thus, the early onset of the South China Sea summer monsoon can be caused. Moreover, when the tropical western Pacific is also in a warming state, convective activities around the Philippines are also strong in summer, since the western Pacific subtropical high abruptly shifts northward in mid-June and early July during its northward advance in this case, the abrupt northward-shift of the East Asian summer monsoon rainband from South China to the Yangtze River and the Huaihe River valleys is obvious in mid-June and this monsoon rainband again jumps northward from the Yangtze River and the Huaihe River valleys to the Yellow River valley, North China and Northeast China in early July.

分析结果表明：当春季热带西太平洋处于暖状态，菲律宾周围对流活动强，在这种情况下，南海上空对流层下层有气旋性距平环流，西太平洋副热带高压偏东，从而使得南海夏季风爆发早；并且，当夏季热带西太平洋也处于暖状态，菲律宾周围对流活动也很强，在这种情况下，西太平洋副热带高压北进时，在6月中旬和7月初存在明显的突跳，从而使得东亚季风雨带在6月中旬明显由华南北跳到江淮流域，并于7月初由江淮流域北跳到黄河流域、华北和东北地区。
