| 为完善老君山科学考察的土地利用基础数据,对森林资源管理“一张图”和国土三调数据进
行空间叠加分析,找出差异,分析原因。结果显示,成果数据在林地、森林、天然林、公益林、湿地面积等方面差异较大。分析认为,差异原因在于影像底图数据、坐标校正参数不同,技术标准、管理属性不同,以及漏划、错划产生的不同结果。对林地保有量、森林覆盖率、天然林资源保有量、生态效益补偿等指标产生较大影响。 针对差异和影响,提出开展差异地块核实,加快林草湿资源普查,加快区域保护利用规划等建议。 |
| 英文摘要: |
| To improve the basic land use data for scientific investigation in the Laojun Mountain area, a
spatial overlay analysis was conducted between the “One Map” for forest resource management and the
third national land resource survey data to identify discrepancies and analyze their causes. The results
showed significant differences in the area of forest land, forest, natural forest, public welfare forest, and
wetland between the two datasets. The analysis suggested that the discrepancies arose from differences in
base map imagery, coordinate correction parameters, technical standards, management attributes, as well
as omissions and misclassifications during mapping. These differences significantly impacted indicators such
as the retention of forest land, forest coverage, retention of natural forest resources, and ecological benefit compensation. In response to these discrepancies and their impacts, recommendations are proposed, including verifying discrepant land parcels, accelerating the comprehensive survey of forestry, grassland,
and wetland resources, and expediting the formulation of regional protection and utilization plans. |
