摘　　要：借助GIS,在对林业与国土一张图做空间叠加分析的基础上,有效衔接两部门一张图中每个斑块的林地管理类型。以林业部门管理的林地基础属性为主线,充分考虑与国土部门认定的林地范围对接,把林地管理类型分为:双方共同认定林地、林业单方认定林地、农用地、未利用地上林地和建设用地上林地。研究结果表明:山区县双方共同认定林地范围差异最小,丘陵县次之,平原盆地县差异最大;山区林业单方认定林地面积占比小,平原区占比大;平原区农用地与未利用地上的林地相对普遍存在,丘陵、山区相对较少;建设用地上的林地面积比例与各地的城镇绿化水平高度相关,一般也是平原区高于山区。Based on spatial overlay analysis to one map of forestry and land with the aid of GIS, forest management types in each plaque are effectively connected in one map of the two departments. With the concept of forest basic management attributes of the forestry department,butt-jointing of the range of forest land identified by the land department is taken into full account and forest management types are divided into forest land joindy determined by the both sides, forest land unilaterally determined by the forestry de-partment , forest land on agricultural and unused land, forest ltind on construction land. The results showed that there is a smaller difference of forest land range jointly determined by the both sides in the mountain- ous county, the hilly county comes second, the plain and basin county has the biggest difference. The mountainous county has the smaller proportion in area and the plain county has the greater proportion in area in forest land unilaterally determined by the forestry department. There is the more forest land on ag-ricultural and unused land in the plain county and the less forest land on agricultural and unused land in the hilly and mountainous counties. The truth is that the proportion of forest land area on construction land is highly relevant to greening level of local urban area. Generally, there is more forest land on construction land in plains and less forest land on construction land in mountainous area.
