川西高山林区森林更新技术研究

Abstract

Abstract: In order to find a way of artifical regeneration after cutting trees in west Sichuan alpine forest region, according to the serious conditions of vegetation and climate, five regeneration test plots were established in Lihuo, Daofu, Wongda counties along altitute from 3620 to 3900m in 1984-1987. Microclimate and stock damage and death on test plots were studied. Some better combination of technique had been found. Using these combination in reforestation, survival rate could reach 97% after transplanting 4 years. Death of young trees was mainly resulted from low temperature in summer and water deficit in winter and spring. By means of change microhabitate silviculture mainly by branch shelter could improve survival rate of trees.

Key words: Alpine, Regeneration technique
