A Geographic Information Systems approach for classifying and mapping forest management category in Baihe Forestry Bureau, Northeast China

这篇论文表明一个地理信息在 Baihe 林地 Burea 分类并且印射森林管理范畴的系统(GIS ) 过程，吉林省，中国。在学习区域以内， Baihe 林地局土地被分类进一个二层次的系统。Thetop 水平班包括了非森林和森林。超过 96% 陆地区域是在学习区域的森林，它进一步被划分成关键生态的服务森林(KES ) ，一般生态的服务森林(GES ) ，和商品森林(COM ) 。COM 盖住 45.0% 全部的陆地区域并且是管理在拜黑·福雷斯特局打的主要森林。KES 和 GES 分别地说明了 21.2% 全部的陆地区域和 29.9% 。在这研究与 GIS 一起设计的森林管理地区当时与用手建立的地区由本地机构拉的森林管理相比。二个产品之间有明显的差别。它建议差别有一些对数据来源，基本单位和印射的过程做。它也建议 GISmethod 是在为分类并且印射森林地区满足分类森林管理系统的需要集成森林库存数据和另外的数据的一个有用工具。

This paper demonstrates a Geographic Information Systems （GIS） procedure of classifying and mapping forest management category in Baihe Forestry Burea, Jilin Province, China. Within the study area, Baihe Forestry Bureau land was classified into a two-hierarchy system. The top-level class included the non-forest and forest. Over 96% of land area is forest in the study area, which was further divided into key ecological service forest （KES）, general ecological service forest （GES）, and commodity forest （COM）. COM covered 45.0% of the total land area and was the major forest management type in Baihe Forest Bureau. KES and GES accounted for 21.2% and 29.9% of the total land area, respectively. The forest management zones designed with GIS in this study were then compared with the forest management zones established using the hand draw by the local agency. There were obvious differences between the two products. It suggested that the differences had some to do with the data sources, basic unit and mapping procedures. It also suggested that the GIS method was a useful tool in integrating forest inventory data and other data for classifying and mapping forest zones to meet the needs of the classified forest management system.
