查询词典 tide pool

in pearl river delta region,water environmental contamination featured big amount and mixed types and centralization of pollutant discharge with latent combined pollutants,striding boundary pollution,severe municipal pollution,the trend of regional pollution being extended from cities to rural area,infall of salty tide in recent years.as a result,the unwatered complexion was hastened due to bad water quality.the factors of water environmental contamination were analyzed as the natural factors including especial hydrographic net distributed pattern,water body runoff characteristic,water resource distributive regional difference,infall of ocean tide,and so forth; the artificial factors as inconsequence of economic development mode and distribution of industry and cities planning,lagging environmental infrastructure,indifferency of environmental consciousness,dissonance of economic development and environmental protection.

珠江三角洲地区水环境污染特点表现为：污染物排放量大、类型杂且集中，潜在复合污染出现，跨界污染突出，城市污染依然严重，并呈现出从城市向农村蔓延的区域性污染趋势，加上近几年咸潮入侵加剧，使区域水质型缺水的局面更趋紧张。造成这种污染局面的因素：一方面受控于区域内特殊的河网分布格局，水体径流特征、水资源分配的地区性差异以及海潮入侵等自然因素；另一方面也反映了区域经济发展模式，工业布局和城市规划不尽合理，环境基础设施滞后，环境意识淡薄，经济发展与环境保护不协调等人为因素所致。

It is shown from the study results that (1) SSC has obvious neap-spring and seasonal variations with periods being 14.7 days and 368 days, respectively, on an average, SSC during the spring tide was 2.96 times as much as that during the neap tide, and SSC in winter was twice as much as that in summer;(2) correlation coefficient between daily SSC and tidal range on the same day in a mean neap-spring period of 15 days was 0.86, and correlation coefficients between tidal range and daily SSC with one day and two day lag were 0.99 and 0.93, respectively, which indicates that the effect of tidal range variation on SSC has a one day or two day hysteresis;(3) the monthly mean SSC was negatively correlated with the monthly mean water discharge at the Changjiang River Datong station, especially well with the water discharge with a lag of 19 days.

悬沙浓度具有显著的大、小潮和季节性变化，变化周期分别为14.7 d和368 d，平均而言，大潮为小潮的2.96倍，冬季为夏季的2倍；2）平均大、小潮半月周期中日悬沙浓度与同日潮差之间的相关系数为0.86，与前1日潮差之间的相关系数为0.99，与前2日潮差之间的相关系数为0.93，反映潮差变化对悬沙浓度的影响有1~2d的滞后效应；3）月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤其与流量滞后19d的相关性最好。
