| 中文摘要: |
| 利用地理信息系统与遥感技术,对2005—2010年湖南省永州市锡矿山矿区生态系统空间格局变化特征进行了定量分析。结果表明,矿区植被面积逐渐减小,而矿山设施、矿山地质灾害、矿区敏感物和采矿场的面积则有所增加；矿区各类型的生态系统之间存在着相互转换的现象,但相互转换的面积并不大；基于景观指数方法的分析发现矿区生态系统的斑块数、各类别的边界密度、生态系统斑块密度均呈现增大趋势,而矿区聚集度指数整体呈现缓慢下降的趋势。 |
| 英文摘要: |
| Based on GIS and RS technology, spatial pattern change of the ecosystem in the Xikuangshan mining area from 2005 to 2010 is analyzed. The results show that the vegetation area in the mining area decreased gradually, while mining facility, geological disaster related to mining activities, sensitive objects in the mining area, and mining stoping areas increased to some extent. There was mutual transformation among these ecosystem types though these areas of transformation were not obvious. On the basis of landscape index analysis, it is found that patch number of mining area, edge density of each ecosystem type, patch density of ecosystem presented a trend of accretion, while the aggregation index of mining area has an opposite trend to decrease gradually. |
