摘    要:利用2013年5-10月对乌海市3个不同沉淀池水质的测定结果,以主要影响滴灌器堵塞因素的泥沙及其他相关指标的相关性作为主要研究对象,应用SPSS统计分析软件进行相关分析。研究结果表明:细菌总数与浊度呈显著正相关,说明泥沙是细菌生长繁殖的载体,泥沙的沉淀池中的含量决定了细菌总的数量。叶绿素a与浊度呈负相关性,说明泥沙的浓度影响水中藻类的生长,而影响不是很大,呈现不明显的相关性。受浊度影响较大的CODMn、氮和磷,延长停留时间更有利于泥沙的吸附沉淀。沉入水底的泥沙中含有大量的N,在一定的条件下会再次将N释放回水中。水中TP含量的变化与泥沙浓度呈线性关系,泥沙量越大吸附越快,同时TP含量越高越易被泥沙吸附。同时证实只要水中有泥沙颗粒,滴灌带中的泥沙必然被细菌附着。

关 键 词:滴灌器堵塞  相关性分析  浊度  环境因子  SPSS软件

Correlation of Environmental Factors for Drip Irrigation Device Block in Yellow River Irrigation Districts
Abstract:Based on the water quality determination results of three different settling basin in Wuhai city in May to October of 2013, with cor-relation of the main factors, including sediment and other related indexes, which influence the drip irrigation device block, as the main re-search object, the SPSS statistical analysis software is applied for correlation analysis. The results show that the total number of bacteria and turbidity is significantly positively related to sediment, which means that sediment is the carrier of the bacteria thrives, and the sediment con-tent of sedimentation tank determines the total number of bacteria; Chlorophyll a has negative correlation with turbidity, which means that sediment concentration affect the growth of algae in water and the effect is not very big, and the correlation is not obvious. CODMn , nitrogen and phosphorus are greatly influenced by turbidity, extending the residence time is good for adsorption of sediment precipitation. Sediment sinking to the bottom contains Large quantity of N, which will be released to water under certain condition;the change of TP content in water has linear relation with the sediment concentration;the bigger sediment content, the faster absorption speed;the bigger TP content, the more easily for TP be absorbed by sediment;meanwhile, it is proved that as long as there exists sediment particle in water, the sediment will inev-itably be attached by bacteria.
Keywords:drip irrigation device block  correlation analysis  turbidity  environment factor  SPSS software
