| 摘 要： | 2004年3～7月，采用系统抽样法在海南岛黎母山对四眼斑水龟（Sacalia quadriocellata）种群密度与空间分布进行了调查，采用Cassie指数、David＆Moore指数、Morisita指数和Lloyd指数测定了四眼斑水龟种群空间分布格局。结果表明，（1）四眼斑水龟种群分布于海拔170～470m范围内，在垂直梯度上呈现不连续的分布状态；（2）在海拔170～470m范围内种群相对密度为0．011～0．050只／笼捕日；（3）种群空间分布呈现聚集分布格局；（4）资源的空间分布特点和人为干扰可能对四眼斑水龟种群密度及空间分布格局有重要影响。 |

| Abstract: | Population density and spatial distribution pattern of Sacalia quadriocellata was studied by regular sampling conducted from March to July of 2004 in Limu Mountain,Hainan Island.Four indices,Cassie index,David & Moore index,Morisita index,and Lloyd index,were used to evaluate the aggregative degree of S.quadriocellata.Populations of S.quadriocellata are scatteredly found at elevations between 170-470 m with a discontinuous pattern.The relative population density is 0.011-0.050 ind./cage-day.The populations are spatially aggregated in their distribution range.Human disturbance and uneven distribution of the natural resources may affect the population density and spatial distribution pattern. |
| Keywords: | Sacalia quadriocellata Population density Spatial distribution pattern Hainan Island |
