本文作为大洋钻探项目船下后续研究的一部分,对184航次中的1146站位和1147 、 1148站位的样品进行了分析和研究,在船上科学家已经建立起的地层框架的基础上进一步加密采样,对生物事件标志化石类别进行数量统计,进一步确定了12个生物事件在钻孔中的深度,建立起了两个站位的高分辨率的钙质超微化石生物地层框架。 - Longgang nature reserve plays an important role in preserving two langur species of both white - headed langur and francois langur . interview and field survey methods were used to survey the distribution and population size of these two langurs in this natural reserve from december 2001 to january 2002 . the result indicated that the reserve has 8 groups of white - headed langur with 68 individuals in longrui and 10 groups of francois langur with 75 individuals in longgang . the distribution area and population size of both of the two langurs in this reserve have greatly declined in the past decades . they are seriously threatened and have high risk of disappearance from this reserve if no effective measures are to be taken at once
为了确定弄岗自然保护区内白头叶猴的种群数量,弥补黑叶猴种群数量的空白,掌握此保护区叶猴的生存现状,采用访问法和实地数量统计法相结合的方法对弄岗自然保护区的弄岗、陇瑞和弄呼3个部分进行深入的调查研究.调查结果表明,在陇瑞片范围内,共有8群白头叶猴,种群大小在68只左右,和20世纪80年代末的244只相比,数量下降相当惊人;在弄岗片内,共记录到黑叶猴群10群,最大的种群为11只个体,最小的种群是4只个体,共计约有75只黑叶猴(绝对数量统计) ;弄呼的黑叶猴种群已经于上个世纪的晚期消失.造成目前状况的因素主要是过度狩猎和其他形式的过度干扰.弄岗自然保护区的叶猴种群数量已经接近可持续繁殖种群的最低水平,如不采取有效的保护措施,这个种群将很可能在短期内消失 - In order to make comprehensive analysis on the changing behaviour , the author has investigated and verified all of the a share listed companies that have changed use of proceeds since the foundation of chinese stock market . firstly , this chapter analyzes the general situation . secondly , this chapter makes detailed statistics and analyses on the 5 aspects of the changing behaviour
