【摘要】 通过遥感解译对日照市海水入侵现状进行分析,对海水入侵程度进行评价,发现养殖池和河滩面积在大幅增加,盐田、滩涂、沙滩等均在减少。在日照沿海地区,地下水的储备与人类的用水需求之间存在矛盾,人类过量开采地下淡水是产生海水入侵的主导因素。建议采取兴建地下水库、减少地下水开采和人工回灌等措施防治海水入侵。更多还原

【Abstract】 Through remote sensing interpretation,present condition of seawater intrusion in Rizhao city is analyzed and intrusion degree is evaluated. It is found that the square of breeding ponds and flood area is increasing greatly,while the square of salt area,mud flat,beach is decreasing gradually. In coastal areas of Rizhao city,there is a contradiction between underground water reserves and human demand. This contradiction It is mainly caused by over-exploitation of underground fresh water. Thus,it is very effective in carrying out some countermesaures to prevent sea water intrusion,such as constructing underground reservoirs,reducing groundwater extraction and recharging artificially.更多还原
