森林资源管理与监测地理信息系统在伐区调查设计中的应用

The Application of Forest Resource Management and Monitoring Geographic Information System to Inventory and Design in Felling Area

应用以“3S”技术为基础的黑龙江省森林资源管理与监测地理信息系统,可以进行林相图、地形图等图库一体化查询,对小班属性查询具有“快捷”、“详细”2种查询方式。应用于伐区调查设计,分别对主伐年伐量、择伐年伐量、散生木年伐量、抚育年伐量、低产林改造年伐量、更新年伐量、卫生伐年伐量的计算方法进行了论述。

The forest resource management and monitoring geographic information system based on ＂35＂ technology are applied to inquire about the unified base and maps including topographic map and forest form map. There are 2 express and detailed inquiring ways to subcompartment attribute in the inventory and design of felling areas. And the calculation methods are elaborated for annual felling amount of principal felling, selective felling, scatter timbers, tending, restructure of low-yield forest, regeneration, satellite cutting respectively.
