摘要
根据湫水河流域林家坪水文站47年降水、径流、泥沙资料,利用水文法建立的模拟降雨径流模型和降雨产沙模型,在此基础上根据降雨资料建立了模拟天然径流量和模拟天然输沙量序列,对因降水变化和人类活动对河川径流及输沙量的影响进行了定量分析,并根据流域内主要的人类活动类型分析了水沙变化的原因。
According to the data of rainfall, runoff and sediment collected by Linjiaping Hydrographic Station in Qiushuihe River Basin, the analog rainfall- runoff model and rainfall sand- production model are established by using hydrographic method, and based on the rainfall data, the analog natural runoff amount and analog natural bed- load caliber sequences are established, and makes quantitative analysis on the influences of the rainfall variations and human activities on the river runoff and the bed- load caliber, and analyzes the reasons of the the water- sand variation based on the forms of human activities.
