Studies On The Forest Resources Monitor By GIS Technologies

The forest took one important resources, including the forest resources in kind (forest, forest product and forest land and so on) and the forest environment resources (self-control water source, maintenance water and soil, cultivate fat soil fertility, accept carbon to spit raise, biodiversity protection, landscape amusement and rest and purification environment and so on). The latter, day by day receives the social attention in particular from all walks of life.Took along with the people to the environmental protection with the care, the forest management already to focus day by day from the past in the timber resources development changes attention many kinds of resources the development, developed from the past pure pursue economic efficiency to the pursue society, the economical and ecology many kinds of benefits, made great strides forward to the sustainable development direction, at the same time, the forest resources monitor changed the environmental protection by the traditional forest resources economical use the goal, in the forest health monitor aspect, the forest resources monitor importance more and more was specially prominent.In order to better definite forest resources quantity, the quality and the monitor forest resources increase and decrease change, the forecast forest grow, the scholars studied, have designed the massive forests and the Judith appraisal model, as well as forest resources appraisal method, target. But as a result of data huge, target not unified, as well as time-limited question, but cannot obtain, the prompt information precisely.This article introduced with emphasis current our country forest resources monitor main technical method, after analysis and comparison, introduced the forestry high technology and new technology with emphasis in the forest resources investigation and in the forest resources monitor application. First introduced 3S technical RS (remote sensing), GIS (geographic information system) and GPS (global positioning system) the concept and the research is intense, as well as in forest resources monitor application present situation.Next, introduced applies the GIS technology, through manufactures each kind of special chart, attains makes a fire the pond tree farm forest spatial distribution pattern method and the...
