摘要
针对“三调”“一张图”和“国情”数据(简称“三类”)在森林资源调查方面的分类标准和认定标准不一致等问题,提出了一种针对“三类”森林资源调查数据的整合方法。该文从森林资源调查工作要求出发,以“三调”数据为底版,通过对“三类”数据进行梳理,实现了“三类”数据的有效整合,并参照0.5 m高分辨率遥感影像,确认林木覆盖范围,较好地弥补了单一数据不能准确反映林木覆盖状况的缺点。实验结果表明:“三类”数据的林木覆盖状况在面积和分布上均存在较大差异,“三类”数据空间整合可以从宏观上较好地反映区域的林木覆盖状况,研究结果对于森林资源专项调查工作中的底图制作具有一定的参考意义。
According to the inconsistency between the classification standards and identification standards of the three types of forest resources investigation data of the third national land survey data,“A Map”of forest resource management and the results of geographical national condition monitoring,this paper presented the integration method for three types of forest resources survey data.Based on the requirements of forest resources survey,this paper takes the third land survey data as the background and combs three types of spatial data to realize the effective integration of three types of data.It confirms forest coverage with reference to 0.5 m high-resolution remote sensing images and makes up for the disadvantage that a single data cannot accurately reflect the forest cover.The experimental results show that the forest cover status of the three types of data are quite different in area and distribution,and the spatial integration of the three types of data can accurately reflect the forest cover status of the region,which is of certain reference significance for base map making of forest resources survey.
