Dynamical monitoring on the ecological forest stand volume in Minjiang watershed based on RS technology;

According to the comparable analysis of nine kinds of measurement method of stand volume on the same China-fir forest,this article provides the optimal methods in different application conditions.

It therefore, provides the referrence for detailed calculation of the stand volume.

At the end of 1970s, 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.

With remote sensing technology being widely used in the investigation of forest resources,especially in the remote sensing estimation of the forest stock volume,remote sensing method can save time,work and budget in comparison with the traditional method.

A lot of foresters use this new technology in the activities of forest resource inventory, especially on estimating forest stock volume.

Basic theory and practice of surveying forest volume and increment with electronic angle gauge.;

Estimation of forest volume in Huzhong forest area based on RS,GIS and ANN;

The application of principal component transformation and Bayesian regularization back propagation (BP)neural network in forest volume estimate was introduced through a specific sample in this paper.

By analyzing data from 77 meteorological stations in Taihang Mountains and from 721 sample plots in different faces of Taihang Mountain, it was approved, through regression, that there was a good relation between temperature and forest growing stock in the whole Taihang Mountain.
