[Landscape diversity and stability of Korean pine broad-leaved forest in Xiaoxing'anling forest region].
Taking the Dongfanghong Forestry Farm of Dailing Forestry Bureau in Heilongjiang Province as the study area, and based on the GIS information and the analysis of current forest management measures, a landscape dynamic model was established, which indicated that the indexes of landscape classification at the first and second levels were rather low, due to the forest covered about 91% of the whole study area. The dominance index of forest cover was increased from 0.611 to 0.692 during the period from 1985 to 1993, and that of climax forest community was increased by 70%. During the years of 2041-2049, the Korean pine broad-leaved forest would become the climax forest community in this area, with an area around 13,120-13,242 hm2 if taking selective cutting as the prevailing harvesting method.
