大沽河 meaning in Chinese
dagu he
Examples
- The measured values coincide well with the simulated ones . the result shows that as to cod and tp , the water quality is up - to the water standard , while to tn , it is not . seawater has been badly polluted in the north - east of jiaozhou bay
大沽河、墨水河和李村河入海口附近水质超四类海水水质标准( gb3097 - 1997 ) :娄山河、红岛沿岸海域水质超过三类海水水质标准;胶州湾超一类水域的面积占湾内面积的64 。 - ( 2 ) along the intertidal zone , the lower of contents of heavy metal exponentially , the farther is from sewage sources . ( 3 ) the concentrations of heavy metal decrease inch by inch from high tidal flat to the middle and low intertidal zone . it is water dynamics that impact on the accumulation features of heavy metals of intertidal
如河套是这五个区域中唯一的非河口区,潮间带沉积物重金属含量全湾最低;大沽河1东营盐场段紧邻大沽河河口,大沽河2营海段远离河口,后者重金属含量普遍低于前者。 - In recent years , many barrages have been founded in dagu river , which greatly change the conditions of the exploitation and supply of groundwater . on the basis of calibration of mathematical model of hydrogeology , the effect of diversified factors on the variation of groundwater is analyzed using visual modflow software , the recharge capacity of rubber dam to the groundwater storage is studied and the allowable withdrawl of groundwater with the influence of manpower is calculated again
近年来大沽河干流及支流已增加多处拦河坝工程致使地下水采补条件发生了较大变化,本文利用visualmodflow软件分析了各种影响因素对地下水动态的影响,研究了橡胶坝对地下水库的补给能力并重新核算了人工影响条件下大沽河地下水库的允许开采量。 - First , the hydrogeological conditions and characteristics are gathered up and the hydrogeological concept model is generalized . next , through collecting completely and analyzing systematically the rainfall , evaporation , surface runoff and observation datum of the groundwater water level , all hydrogeological parameters of this area is defined , then mathematical model of groundwater of dagu river is built
首先概括大沽河地下水库的水文地质条件与特征,概化出该区水文地质概念模型,然后通过全面收集和系统分析研究区的降雨、蒸发、地表径流、灌溉和地下水水位常观资料,确定该区的各项水文地质参数,进而建立了该区地下水的数值模型。 - The results are as follows : ( 1 ) if we increase the pumping water by 493 x 104m3 , the amount of leakage recharge of rubber dam will rise by 231x 104m3 ; which indicates pumping by rubber dam can excite much more surface water infiltrate so as to supply groundwater . thus the utilization ratio of water source is increased , and it provides the reliable guaranty for enough supply of the groundwater storage in wet year . ( 2 ) under the condition of present status , the groundwater exploitable resource in wet year is 3670 104m3
最后,通过数值法反复调算计算出本区地下水的允许开采量,计算结果表明,在现状开采的条件下,大沽河地下水库丰水年( p = 20 )时地下水允许开采量为13670 10 ~ 4m ~ 3 ,平水年( p = 50 )时地下水允许开采量为12054 10 ~ 4m ~ 3 ,枯水年( p =加% )时地下水允许开采量为10951xl了砰。
