滨海旅游对北海银滩生态环境的影响

通过对北海银滩海水浴场调查与采集海水与沙滩沙进行检测,结果表明:北海银滩海水浴场质量良好,适宜游泳。沙滩颜色隐约变深,有的地方变黑,银滩沙子有机质含量为0-0.60g/kg,无机氮含量0-11.35mg/kg,可溶性磷含量0-5.74mg/kg,可溶性钾含量0-7.69mg/kg,趋于富营养化。

The investigation and collection of sea water and sand in Beihai Yintan （Silver Beach） are carried out. The results show that Beihai Yintan（Silver Beach） is of good quality and suitable for swimming. Sand organic matter content was 0-0.60 g/kg, inorganic nitrogen content was 0-11.35 mg/kg, soluble phosphorus content was 0-5.74 mg/kg, soluble potassium content was 0-7.69 mg/ kg, thus tending to eutrophication.
