长白山北部林区检查法经营云冷杉林对枯落物分解及土壤含水率的影响

Effects of Control Method on Spruce fir Forest′ Litter Decomposi tion and Soil Moisture Content in North Changbai Mountains

论述了检查法(少量、多次择伐法)不同作业方式对长白山北部云冷杉林下枯落物、土壤含水量及枯落物分解速率的影响。认为进行检查法作业后枯落物蓄水能力提高,但土壤含水量差异不大,枯落物分解速率加快。

The article studies the effects on spruce fir forests′ litter and soil moisture content and litters′ decomposing rate under different management system in north Changbai Mountains.The author indicates that spruce fir forests′ litter layer can retain more water and decompose rapidly after control method. But it hasn’t much difference on soil moisture content. Spruce fir forests play an important role in this area and should be well protected. The author emphasizes that cutting off should be selected very carefully to maintain the forests′ special environment.
