In this paper the relationships between forest density and index of decline disease, and soil moisture content were studied and determined in Pinus taeda plantations in Anhui province.

Through real surveying material, the paper determines the influence of forest density and felling intensity to stander damage and finds out changing regulation.

The structure characters of broad-leaved woodland I.The relationship between stand age and stand density;

Effects of Pinus massoniana plantation stand density on understory vegetation and soil properties

Relations of stand density and the biomass of the artificial young Larix principis-rupprechtii forest

Comparison of poplar stands thinned with no thinned in the forest farm in Chaoyang County indicated that the Current annual increment of the dense stand through thinning raised obviously.

Based on the model compatibility, the whole stand model for papermaking and raw material stand of masson pine has been made by establishing the dynamic predicting model of stand density index with Korf equation in accordance with the auxiliary variables of age, site index and original planting density.
