摘要
因广西防城金花茶国家级自然保护区面临着金花茶Camellia chrysanthoides被偷采、滥挖的风险,文中应用GIS中的最小费用路径(LCP)模型,以土地覆盖、坡度、距离为因子,模拟了偷采者可能的潜入路线。共选取了65个金花茶分布点,40个保护区入口点,模拟出2600条最小费用路径。用自然断点分类法找出了重叠度高的"热点"区域。基于"热点区域"提出了一种视频监控点布局方案,规划了7个视频监控点,目的是覆盖偷采者最可能的潜入路径,更好地保护稀有的金花茶。
Since Camellia chrysanthoides was facing the risk of illegal picking and digging in Fangcherig Camellia chrysanthoides Nature Reserve, the land cover, the slope and the distance were selected as fac-tors in least cost path (LCP) model to simulate the possible routes of the stealer. A total of 65 distribu- tion points and 40 entrances were chosen and 2600 least cost paths were produced. The "hotspots" with high overlap degree were identified by the classification method of natural breaks to present the layout scheme of video monitoring point and select 7 video monitoring points in the nature reserve to cover the possible routes of stealer and improve the protection efficiency.
