Indicators, and the main technical indicators of timber production, silviculture, multi-use and

限额和各林场的森林资源状况，确定各林场的年木材采伐量，组织森林作业调查设计

At present Austrian forest is enclothed rate already amounted to 46.2%, the wood that has 2/3 is close wildwood, fall greatly under grow quantity.

目前奥地利森林覆盖率已达46.2%，有2/3的森林为近自然林，采伐量大大低于生长量。

The system can directly display, store, calculate and analyze the details of the forestry resources information provided by the different organizations of the whole city. It can also store the surveying results of the planning and designing on forestry resources into the database and update in real time the sublot attribute information according to of the planting or the cutting volume. Further more, it could be used to approve timber cutting design online.

该系统可以直观地显示、存储、统计和分析全市各编限单位的森林资源消长信息；可以将森林资源规划设计的调查成果存储于数据库中，根据采伐量或栽种量实时更新小班属性信息；可以网上审批采伐设计书等。

Implementation of the requirements for intensive management of commercial forests, and to determine the reasonable amount of logging in; banned to protect the forests of the main stand a better site conditions, the test can be stratified business uneven-aged forest; Yilin according to the site conditions Provides a different mode of reforestation; priority to the development of the industrialization of edible fungi, mountain vegetables, almonds, fruit juice, and other items.
