海水酸化对鹿角珊瑚光谱特性影响的分析
Keywords: 海水酸化,造礁珊瑚,光谱特性
Abstract:
？海水酸化造成全球珊瑚礁严重退化,应用卫星遥感手段可以快速地对珊瑚礁进行监测。在野外做酸度对比实验具有条件不易控制、周期长等局限性。文章提出一种室内测量珊瑚光谱的方法,通过比较不同酸度梯度下珊瑚光谱的变化,为研究海水酸化对珊瑚的影响提供了一种新的思路。试验采用7.6、7.9和8.1的酸度梯度,结果表明:在ph为8.1和7.9环境条件下,珊瑚的光谱趋势大体一致,总体上珊瑚光谱波峰出现了向长波方向的红移。但是在ph为7.6的条件下,珊瑚的光谱在650~700nm之间出现一个反常的吸收谷,这是由于ph7.6的酸度条件适宜一些藻类生长,藻类附着在珊瑚表面,从而影响了其光谱特性。
