广西壮族自治区地处低纬,全区多年平均降雨量1525毫米。由于雨量充沛,汛期洪水频繁,极易给沿江地区造成洪灾。因此,全区水文情报预报任务比重繁重。目前,全区已布设908个雨量站点。但具有报汛能力的只有330多个站。当特大的或局部的暴雨到来时,仅依靠现有情报站往往不能很好控制雨情而影响预报精度,不利防洪抗灾。 Guangxi Zhuang Autonomous Region is located in low latitude, the region’s average annual rainfall of 1525 mm. Due to abundant rainfall, the flooding in flood season is frequent, which can easily flood the riverside area. Therefore, the heavy hydrological intelligence forecast tasks heavy workload. At present, the region has laid 908 rainfall sites. However, it has only more than 330 stations that have the ability to report floods. When large or partial heavy rain arrives, relying on the existing information stations often can not control the rain well and affect the forecasting accuracy and adverse flood prevention and disaster relief.
