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。
With the aid of GIS, based on the spatial superposition analysis of a map of forestry and land, the effective management of the woodland management type of each plaque in the two departments and one map is validated. Taking the basic forestland property managed by the forestry sector as the main line, we fully consider the docking with the scope of the forestland identified by the land administration department. The types of forestland management are divided into the following: the two sides jointly identify the forestland, the forestry unilaterally identifies the forestland, the agricultural land, the unused forestland on the ground and the construction land woodland. The results showed that: the two counties in Shanxian County jointly identified the smallest differences in forest area, followed by Hilly County and the lowest in plain basin counties; the unmarried areas in mountainous areas had a small proportion of forest land area and a large proportion in plain area; and the agricultural land and unutilized land area in plain area Forest land is relatively ubiquitous, with relatively few hilly and mountainous areas. The proportion of forest land on construction land is highly correlated with the urban greening level in various places, and is generally higher in plain areas than in mountainous areas.
