摘要
自然保护区时常受到人类的干扰与破坏,保护区的管理工作面临着巨大的挑战。本文提出以保护物种多样性为目标的视频监控选址方案,基于集合覆盖模型研究视频监控的优化选址,要求在全覆盖指定物种的情况下,安装的视频监控点数量最少。并且在选址模型存在多个优化解的基础上,选取监控总面积最大的方案作为最优解。本文以监控云南轿子山保护区的7个物种为例,求解出布设10个监控点的最优方案,这些监控点都位于视野开阔的山脊线上,监控面积占保护区总面积的93%。该方法能有效提高保护区的管理效率。
Facing disruption and destruction from mankind, the management of natural reserves face enormous challenges. This paper proposed a species-targeted video surveillance site selection program. Based on set-covering model, we are trying to find a video surveillance portfolio which covers all the specified species with minimum number of video surveillances. Providing there are multiple optimal solutions, we tend to choose the portfolio with maximum monitoring area. Taking Mt. Sedan-chair Natural Reserve in Yunnan Province as an example, we find an optimal solution which includes 10 video surveillances and they are all located on the mountain ridges. The monitoring area accounts for 93% of the total area of the reserve. We believe this method can improve the management efficiency of natural reserves.
