　　摘要：寧夏水網具有流量變化級差大、含沙量高、風期長、風速大等區域特點，流量在線設備安裝平臺方面缺乏系統性的研究與實踐。針對寧夏區域水網特點和流域特性，分析各類非接觸式流量自動在線監測設備安裝現狀及建設需求，提出安裝平臺設計思路，重點研究不同斷面跨度、環境影響條件下的河(溝、渠)非接觸式雷達波流量自動在線設備安裝平臺設計，并在4處天然河流、17處引黃灌區取水干渠和排水溝道水文監測斷面開展安裝方式的研究與實踐，解決多種設備類型、不同跨度監測斷面非接觸式雷達波流量自動在線監測設備安裝問題，提升流量自動在線監測設備安裝可靠性、穩定性和監測精度，在寧夏及西北相似地區水文水資源監測領域具有一定的推廣應用價值。

　　Abstract：Ningxia water network is characterized by large discharge difference, high sediment concentration, long wind period and high wind speed. And it is a lack of systematic research and practice in the installation platform of online flow equipment. According to the characteristics of Ningxia water network and watershed, the installation status and construction requirements of various kinds of non-contact flow automatic online monitoring equipment are analyzed, and the design ideas of installation platform are put forward. This paper focuses on the design of on-line installation platform for non-contact radar wave flow equipment in rivers (ditches and canals) under different cross-section spans and environmental conditions. Research and practice of the installation method are carried out in the hydrological monitoring sections of 4 natural rivers, 17 main water intake channels and drainage channels in the Yellow River diversion irrigation area, to solve the installation problem of automatic flow on-line monitoring equipment of non-contact radar with various equipment types and different span monitoring sections, and to improve the installation reliability, stability and monitoring accuracy of automatic flow on-line monitoring equipment. The research has a certain popularization and application value in the field of hydrological and water resources monitoring in Ningxia and similar areas in northwest China.
