保护性林地砍伐事件空间分布特征及风险评估研究

Spatial Distribution Characteristics and Risk Assessment of Deforestation Events in Protective Forest Land

严守生态红线,保护森林资源,是构建生态文明,推动绿色发展的重要措施。及时掌握林地的变化,尽早发现林地的破坏行为,对森林资源保护和管理具有重要意义。目前对于林地砍伐等破坏行为的监测都是被动与事后的,如何主动地进行防范,对易发生砍伐的区域进行高频次全方位的监管,就需要探究林地砍伐区域的空间分布特征,评估和预测林地砍伐的风险。基于多源遥感变化检测和实地调查获取海南省保亭县公益林连续2 a林地砍伐的图斑,研究林地砍伐与人为活动和地形地貌的关系,进而评估林地砍伐风险,为地方林业部门开展更具针对性的巡查、监测和保护措施提供支持,加强林地监管的有效性,真正将林地砍伐等破坏行为遏制在萌芽阶段,严守生态红线,推动生态文明建设。

Strictly observing the ecological red line and protecting forest resources are important measures to build an ecological civilization and promote green development. It is of great significance for forest resource protection and management to grasp the changes of forest land in time and detect the forest destruction as soon as possible. Currently,the monitoring of deforestation and other destructive behaviors is passive and ex post. It is necessary to exploring the spatial distribution of deforest areas,evaluating and predict the risk of deforestation to prevent the occurrence of deforestation by Comprehensive supervise areas which are prone to deforestation.This article is based on deforest change maps of Baoting County,Hainan Province,which obtain by multisource remote sensing change detection and field surveys during two consecutive years,to study the relationship between deforest areas and human activities,topography and landforms,and then to assess the risk of deforest,providing support for local forestry departments to carry out more targeted inspections,monitoring and protection measures,strengthen the effectiveness of forestland supervision,truly destructive behaviors such as deforest in the embryonic stage,strictly abiding by the ecological red line,and promoting the construction of ecological civilization.
