林班

而地形图和在此基础上形成的DEM图除对森林植被分类具有参考价值外，同时对区划小班、林班也具有重要的应用价值进而对TM影像数据处理，得出广州市中心城区森林植被分类情况。

Map and derived DEM has important effect not only on classification , but also on stand division . The relationship of vegetation indexes and vegetation classes were developed based on the landsat TM data of Guangzhou City center district forest classification .

自然保护区林班优先保护排序与评价

Priority Ordination and Evaluation for Conservation of Forest Compartments in Nature Reserve

林班潜在火险等级图的研制与应用3、16林班森林面积比重低，整体结构不合理；

Development and application of the potential compartment forest-fire danger grade map 3 was the lowest .

16林班森林面积比重低，整体结构不合理；自然保护区林班优先保护排序与评价

Was the lowest . Priority Ordination and Evaluation for Conservation of Forest Compartments in Nature Reserve

在林班的水平上，经营目标方程包括两个组成部分：净现值和均衡木材收获值。

On the compartment level , the objective function includes two components : Net Present Worth and Even Flow of the timber harvest .

在本研究中，以德国北部一片包括21个小班的挪威云杉林班的一个中期计划为例，说明多林分发展这一经营系统在实际生产中的应用。

In the present study , an example of Norway spruce compartment in Northern Germany including 21 stands is used to illustrate the approach .

四川生态环境质量评价等级图；林班潜在火险等级图的研制与应用

Using the numerical analytical method , the regional quality of eco-environment was contrasted . DEVELOPMENT AND APPLICATION OF THE POTENTIAL COMPARTMENT FOREST-FIRE DANGER GRADE MAP

在1、2、3、5林班森林斑块破碎化程度大于灌木林、未成林、宜林地和疏林地；

Patch fragmentation index of forest was higher than that of shrub , afforestation land , suitable forest land , woodland in No. 1,2,3,5 compartments .

并以吉林林学院实验林场为基地，研制了该场的林班潜在火险等级图，以及该图的具体应用。

Taking forest experiment station of Jilin Forest Institute as base , the potential compartment forest-fire danger grade map and its concert application have been developed .

在无居民点的13、14、15林班，森林斑块的分离度小于非林地、宜林地，分离度最大的是未成林。

For No. 13,14,15 compartments without human disturbance , the isolation degree of forest land was lower than nonforest land , suitable forest land , while that of afforestation was the lowest .

研究结果表明，该图像已具有一定的几何精度，有较好的可供作境界线、林班线区划的地性线信息，以及土地和森林类型的可判性。

The results show , as for as the images concerned , they possess considerable geometric accuracy and provide better information on boundary and compartmental lines and the ability of distinguish for land and forest types .
