摘要

排水面积比法是将附近站点测量到的日或月流量与大坝断面与站点的排水面积之比提高到指数(n)的实数相乘，将其转移到待建大坝的未测量断面，通常取n为1。首先，利用坝段附近两个站点在同一条河流或相邻河流上的日流量，具有共同的N年长测量记录，提出对365对日流量拟合365个线性回归，并将其与流域面积比联系起来，用365个属于一天的N来计算坝段日流量。其次，采用与月流量相同的分析模型，将12个月的流量转移到坝段。研究了五种不同版本的排水面积比法，其中三种是常指数法，最后一种n = 1的排水面积比法相对最差。

A few versions of the drainage-area ratio method for transfer of daily or monthly stream flows

By the drainage-area ratio method, the daily or monthly flows gauged at a nearby station are transferred to an ungauged section where a dam is to be built by multiplying them by the real number resulting from raising the ratio of the drainage areas of the dam section and of the station to an exponent (n). Commonly n is taken as 1. First, using the daily flows of two stations nearby the dam section on the same stream or on a neighboring stream, having a common N-year long gauging record, it is proposed that 365 linear regressions be fitted to N pairs of 365 daily flows, and relating them to the drainage area ratios, daily flows at the dam section be computed using 365 n's each belonging to a day. Next, by the same analytical model applied to the monthly flows, 12 monthly flows are transferred to the dam section. Five versions of the drainage-area ratio method, three of which with constant exponents, are investigated, and the last one with n = 1 is found to be relatively the worst.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
