以绥阳林业局十文字林场两期森林经理调查数据为基础，以地理信息系统为技术平台，建立了该林场两期的森林资源地理空间数据库，实现了两期森林资源的数字重现，分析了41 a间森林资源数量和空间分布的变化过程。结果表明：该地区41 a间有林地面积增加，森林覆盖率和土地利用率都有所增长，但林分的年龄结构变化不合理，幼中龄林占据主导地位，成过熟林资源严重不足。

Based on the data for two-period forest survey in Suiyang Forestry Bureau,taking GIS as technology platform,two-period forest resource geospatial database was established in Shiwenzi Forest Farm.Digital reproduc-tion of two-period forest resources was realized.Change process of number and spatial distribution for forest re-sources among 41 years were analyzed.Result shows that the area among 41 years,area of forestland increases, forest cover and land use are all on the rise,but the change of age structure for stand is unreasonable,young and middle-aged forest occupy a leading position,resource of mature forest and over-mature forest is seriously insuffi-cient.
