物种多样性物种多样性species diversity wuzhong duoyangxing物种多样性(s Pecle，diversitx)一定区域内物种的多样化及其变化，包括一定区域内生物区系的状况(如受威胁状况和特有性等)、形成、演化、分布格局及其维持机制等。生态学中的物种多样性则是对生物群落组织化水平的度量，与此处的物种多样性，即生物多样性物种水平的多样性有所不同。 物种多样性的测度有多种方法，但一般多采用物种丰富度指数，即一定区域内物种的数目来测定。在此基础上，还应尽量考虑物种的质量特征。①物种之间亲缘关系的远近也表明一种“距离”或差异，也从一个方面反映多样性的程度。如一个有两种蛇和一种鸟的岛屿的多样性应高于一个只有3种蛇的岛屿，即考虑分类学多样性。②由于不同生物种群的研究基础有很大差异，实践中往往选择易于鉴定且意义较大的类群进行测度，而不可能包括所有的生物类群。一般先选择维管束植物、哺乳动物和鸟类，其次包括其他的脊椎动物、大型无脊椎动物、苔醉、地衣、藻类和真菌等。很少有人包括土壤生物在内。③物种多样性测度还应考虑不同物种的量的差异，即物种的相对多度。 对大多数生物类群而言，物种丰富指数在空间上表现出从两极向热带不断增加的规律。物种多样性还受到当地地貌、气候和环境的影响，同时也会打上地质历史变迁的烙印。一般说来热带雨林、珊瑚礁、大型的热带湖泊，甚至可能包括深海是物种多样性最丰富的生境。目前已记录的生物物种为140、170万种，其中一半以上的物种分布在热带地区。据E.O.威尔森1992年的统计资料，全球已记录的生物为141 .3万种，其中昆虫75.1万种，其他动物28.1万种，高等植物24.84万种，真菌6.9万种，真核单细胞有机体3.08万种，藻类2.69万种，细菌等0.48万种，病毒0.1万种。有人估计全世界生物总数在2(X)万~1亿种之间，但大多数人认为5《X)~1戊0万种这个估计数字是比较可靠的。 近年来，人类活动的加剧给物种多样性造成了严重的威胁，现在物种灭绝的速度可达自然灭绝速度的1仪幻倍。目前，全世界大约有10%~巧%的物种面临严重威胁。若不采取有力的措施，物种灭绝的速度还会加快。这种局面已引起国际社会的普遍关注。我们虽然已经采取了一系列措施，但还不能完全扼制物种受威胁，甚至灭绝的态势。(马克平)
