森林采伐与森林培育的过程影响着森林生态环境的变化,作者参加了黑龙江省森工系统的林业土壤普查试点,现就森林采伐与森林培育对土壤因子的影响分析如下:一、森林采伐对土壤因子的影响土壤是森林生长、发育的基地.森林采伐后未能更新,森林土壤会发生一系列的变化,如表土层流失、土壤冲刷、草被植物侵入、地下水位上升等均影响着土壤因子的变化.由此形成的土壤有:(一)草甸暗棕壤(Meadow darkbrown forest soil)一般分布在山地平缓地势较低的老采伐迹地(图1)。
The process of forest harvesting and forest cultivation affects the changes of forest ecological environment. The author participated in the forestry soil census pilot of the forest industry system in Heilongjiang Province. The impact of forest harvesting and forest cultivation on soil factors is analyzed as follows: Factors Affecting Soil is the base for forest growth and development. After forest harvesting, the forest soil can not be renewed. A series of changes occur in forest soils, such as topsoil loss, soil erosion, intrusion of vegetation and groundwater level, affect soil factors The resulting soils are: (i) Meadow darkbrown forest soil is generally distributed in the lower, well-logged old deforested areas of the mountain (Figure 1).
