| 摘 要： | 以油松、华北落叶松人工林为主要对象,研究了抚育间伐对林地土壤理化性质及微生物的影响,结果显示:1)抚育后土壤含水量增加。增加效果最显著的是采伐强度为30%的样地。抚育后土壤最大持水量、最小持水量及毛管持水量都明显增加;2)抚育间伐能够促进有全N含量的增加,全N含量由大到小依次为:抚育强度30%的样地>20%样地>10%样地;全P、全K变化差异较小,抚育后效果不明显;抚育对土壤的pH值影响不大,抚育能增加有机质含量;3)抚育后油松、落叶松样地无论是好气性细菌数量还是厌气性细菌数量都比对照样地有所增加。油松抚育间伐样地从细菌总数来看超出对照样地的78%。落叶松总细菌数高出对照4号样地37.9%,抚育对细菌的增加有明显地促进作用。

| Abstract: | With Chinese Pine and Larix spp.as the research object this paper mainly talks about the tending felling effects on soil physicochemical characteristics.The research results shows:(1)Aerobic and anaerobic bacterium in tended Chinese pine and Larix spp plots are more than checked sample plots.(2)There is obvious increase of the soil PH value after tending,soil organic matters are increased.(3)Tending has promoted the increase of P,K.Soil pondage,capillary moisture capacity and total porosity obviously after tending. |
