摘要
丹东市是辽宁省森林资源分布最为丰富的区域之一,但是其区域内山高峰险,现地森林资源调查困难且投入大。应用遥感的方法对丹东进行森林资源估算,可以达到节省人力物力资源、避免现地调查危险的目的。研究通过1 km×1 km公里网格布设样地,运用遥感判读的方法对丹东市2015~2018年的森林资源数据进行了估算并与森林资源“一张图”结果进行了对比分析,经过检验证实了研究结果科学合理。估算得出:2018年丹东森林面积989430 hm^(2),覆被率65%。由此可见,此估算方法适用于市级对森林资源的监测,进而可为森林经营政策的制定提供数据支持。
Dandong is one of the areas with the most abundant forest resources in Liaoning Province.But the mountain peaks,the forest on-site investigation was difficult with large investment.Using remote sensing technology to monitor forest resources can save manpower and material resources and avoid the danger of on-site investigation.Therefore,the sample plots were arranged in a grid of 1km×1km,and the remote sensing interpretation method was used to estimate the forest resources data of Dandong City from^(2)015 to 2018.The results of the“one map”of forest resources were analyzed.The results were proved to be scientific and reasonable.It is estimated that in 2018,the forest area of Dandong was 989,430 hectares,with a coverage rate of 65%.Thus,it can be seen that estimation method was suitable for monitoring municipal forest resources,and provided data support for the formulation of forest management policy.
