| 中文摘要: |
| 2009年9～12月以4只大猩猩(Gorilla gorilla)为研究对象,应用瞬时扫描取样法观察记录其活动行为,建立不同取样间隔与数据准确性和数据独立性的线性回归方程,计算变量系数和常数项的95%置信区间,进而确定瞬时扫描法的最适取样间隔。研究结果表明,大猩猩活动主要集中于上午10:00～11:00时和下午14:00～15:00时(χ2=19.110,df=4,P=0.001),不同大猩猩个体间活动行为存在显著差异(Kruskal Wallis Test,χ2=11.229,df=3,P=0.011)。随着取样间隔的增大,间隔取样与连续取样数据的相关系数呈下降趋势,满足数据准确性需求的最适取样间隔为3～13 min,随取样间隔的增大,数据独立可能性逐渐升高,其中满足数据独立性需求的最适取样间隔为2～8 min。综合考虑以上两种因素,确定针对大猩猩活动行为的瞬时扫描取样的最适间隔为3～8 min。 |

| Through instantaneous sample method,we observed 4 Gorilla(Gorilla gorilla) individuals in Shanghai Zoo from September to December 2009 to determine appropriate sampling interval to separate two consecutive observation.The focus animals were active during 10: 00-11: 00 and 14: 00-15: 00,and significant difference in active frequency between individuals was detected.The appropriate sample interval is 3-13 min.Data accuracy would be reduced and data independence would be increase when increase sampling interval.The appropriate sample interval supposed by this study is 2－8 min.Here，a compromised sample interval of 3－8 min is considered. |
