摘　　要：河道疏浚是一种加强防洪排涝能力,现代农业灌溉供水,改善区域内水环境及保护水资源,提高水质的工作。河道疏浚体是河道疏浚工程实施前需要查明的一项关键工作,关系到往后政府投资决策、资源利用等关键问题。本文以儋州市山鸡江三段河道疏浚工程地质调查为例,论述对河道疏浚体进行地质调查工作中采取疏浚河道段地形测量、岩芯钻探、样品分析试验等方法,查明疏浚体规模、形态、主要成分(中砂)、规格类别及开采条件,明确疏浚体资源用途类型,通过地质理论计算出疏浚体量,分析探讨在生态环境保护和建设用砂资源短缺情况下,重视河道疏浚工程中疏浚体的价值和资源利用,短期内可解决海南局部地区建设用砂紧张等问题。同时也带动河道疏浚地区经济发展和增加地方政府的收入。River dredging is a work that strengthens flood control and drainage capacity,increases modern agricultural irrigation water supply,improves the water environment in the region,protects water resources,and improves water quality.River dredging is a key content that needs to be ascertained before the implementation of a river dredging project,and it is related to key issues such as future government investment decisions and resource utilization.This paper takes the geological survey of the third section of the Shanji river in Danzhou city as an example,discusses the methods of topographic survey,core drilling,sample analysis and testing of the dredged section of the river in the geological survey,to ascertain the scale,form,main component(medium sand),specifications and mining conditions of the dredged body,clarify the type of dredged resource use,calculate the dredged volume through geological theory,analyze and discuss the resource utilization value of dredged bodies in river dredging projects under the condition of ecological environment protection and construction sand resources shortage,in order to achieve the short-term goal of solving problems such as the shortage of construction sand in some areas of Hainan.At the same time,it also drives the economic development of river dredging areas and increases local government revenue.
