Goal Community,landscape Pattern and "Disparity"——A New Visual Angle for the Evaluation of Bush Vitality;

The bush vitality is the growing and regeneration capability of the bush,it is mostly influenced and restricted by the vertical structure function and the horizontal landscape pattern.

Spatial pattern and variance of forest productivity based on remote sensing and GIS;

in order to enhance way in forest productivity in Hubei province based on documents collected and sorted out during II type survey achievement in the third forest resource in Hubei Province through analysis on current status of the forest productivity, which offers.

The established models in which annual precipitation was incorporated as the principal variable indicate a very closely correlation between forest productivity and its corresponding climatic factors,allowing to simulate distribution pattern of actual forest productivity effectiv.

Study of Distributed Simulation Oriented Provincial Forest Carrying Capacity Estimate System;

For harmonizing the relationship between forest use and conservation,it is necessary to evaluate the forest carrying capacity in a region timely.

The evaluation of forest carrying capacity (FCC) is an important content of forest sustainability evaluation, and it is also an important evaluation index of the capacity of sustainable development in regional society.

According to climate data and forest resource data,the forest potential productivity of Linkou forestry bureau in Heilongjiang Province was calculated by using Miami model and Thornthwaite Memorial model.
