The Ridge Parameter for Forest Stock Volume Quantitative Estimation

森林蓄积定量估测的岭估计参数

However , in the view of forest stock volume and forest land area , state-owned forest resources play an dominant in forest resources .

但从林地面积和林业蓄积量上来看，国有森林资源在森林资源中占据主导地位。

The study is a new attempt that uses Landsat TM image and some ground sampling plots by multi-analysis method to estimate forest stock volume .

本研究是用陆地卫星TM图象和多元分析方法直接估测森林蓄积量的一次新尝试。

To overcome the possible influence of multi-correlation between the factors of remote sensing and GIS influencing forest stock volume estimation , forest stock volume estimation equations were established with ridge estimation .

为克服影响森林蓄积估测的遥感和GIS因子间可能存在多重相关性的影响，采用岭估计建立森林蓄积估测方程。

The forest stock volume is an important part of the forest resources investigation . The traditional survey of the forest resources is a kind of work which has a long cycle , needs heavy tasks and intensive labor and will need the massive funds .

森林蓄积量是林业资源调查的重要内容之一，传统的森林资源调查是一项周期长、任务重、劳动强度大，需大量经费的工作。

Standard Effect of Forest Canopy Density on Stock Volume Estimation

森林郁闭度对蓄积量估测的影响规律

In order to establish the forest canopy density and stock volume estimation equation based on remote sensing and GIS in the monitoring area , it 's needed to sample certain amounts of representative sample plots .

为建立监测区域以遥感和GIS为基础的森林郁闭度及蓄积定量估测方程，需在监测区域抽取一定数量有代表性的样地。

At the end of1970s , remote sensing technology was introduced into China and has been used since then in the activities of forest resource inventory , especially in estimating forest stock volume .

以中国林科院为主的一批林业科学工作者，积极将其应用于森林资源调查工作，特别是森林蓄积量的估测。

Hunan is one of key forest zone in our country . By the end of 2010 , the forest coverage rate reached 57.01 % , and the forest stock volume reached 402 million cubic meters .

湖南是全国重点林区之一，到2010年底，森林覆盖率达到了57.01%，森林蓄积量达到了4.02亿立方米。
