| 摘要: |
| 采用广东省土地利用规划图和各自然保护区总体规划资料,在GIS软件ARCGIS8.0和MAPGIS支持下提取广东省省级以上森林生态系统自然保护区的空间资料,对区域水平上广东省省级以上森林生态系统自然保护区空间分布格局进行了研究。结果表明,目前广东省已建立自然保护区在区域空间水平上表现为随机分布,但保护区间连接度较差;保护区之间的隔离程度表现出显著的差别,基本可以区分为3个类别,其中空间隔离最大的保护区有9个,占已建立保护区的28%。因此,在广东省自然保护区建设过程中,应做好选点工作,增加自然保护区的空间连接度。 |

| Study on the spatial pattern of the national and provincial forest ecosystem reserve in Guangdong Province |

| Abstract: |
| Based on GIS by utilizing soil utilization planning map and the planning map of each reserve,the spatial pattern of the national and provincial forest ecosystem reserve in Guangdong Province were analyzed in order to provide theoretical basis for making choice of site to establish natural reserve.Results showed that the spatial distribution of the established national and provincial forest ecosystem reserve was random under the regional scale,whereas the spatial connectivity was low;there were significant differences in the spatial isolation among reserves and based on spatial isolation the reserve could be categorized to three types in which there were 9 reserves with the greatest spatial isolation,accounting for 28 percent of the total number of the established national and provincial forest ecosystem reserve.Based on the above result,the work that makes choice of site to increase the spatial connectivity should be well done during establishing the natural reserves in Guangdong Province. |
