集约化种植区地下水水质劣化的影响因素

Groundwater Quality Degradation Influencing Factors in Intensive Cropping Area

集约化种植长期大量使用农药、化肥、农膜及大型机械,导致多种农药化合物污染和重金属累积。淋溶或地下水径流过程可将这些有害物质携带至地下水中,长此以往地下水水质恶化。以山东某村集约化种植区为例,采集地下水、土壤样品,分析集约化种植地区地下水污染特征及其影响因素,给出防治对策。

Long-term heavy use of pesticides, chemical fertilizers, agricultural films and large machinery in intensive cropping area lead to a variety of pesticide compounds pollution and accumulation of heavy metals, these harmful material through leaching and runoff into the water bodies then resulting in deterioration of groundwater quality. This work got some groundwater and soil samples in some villages as intensive are- a in Shandong Province for case study, analyses the intensive planting area of groundwater pollution characteristics and its influencing factors, prevention and control countermeasures and suggestions are given.
