项目摘要

1. Exchangeable cation in forest soil. increased doe to the advance of urbanization along Tama River. Soil acidity was consequently neutralized in urban area.2. In secondary forest of Quercus serrata in Sayama Hill., the mineralization and nitrification of soil were studied in relation to forest management and micro topography. In crest-slope, the concentrations of NH_4-N and NO_3-N were high. In side-slope, NH_4-N was high and NO_3-N was low. In head-hollow, the proportion of NO_3-N was high. Forest cutting reduced the supply of organic matter to soil and decreased the mineralization rate. Though it also increased the nitrification rate, the content of mineral nitrogen was decreased due to the increase of the outflow of nitrate and the increase of nitrate-favoring plants.3. 299 stands of secondary forest of in Sayama Hill were classified into 7 categories due to underlayer flora. The primary separation occurred between coppiced stands and natural stands. The secondary separation occur … More red among micro topographical types. Species abundance was fewest in dwarf-bamboo dominant stands and Eurya dominant stands.4. The occurrence of mushroom was studied in Sayama Hill for 3 years. Ectomycorrhizal fungi was much in slope and few in head hollow. In ectomycorrhizal fungi, Amanitaceae and Boletaceae occurred much on slope, but Russulaceae occurred on both of slope and head-hollow. Ectomycorrhizal fungi decreased in coppiced stands, where the proportion of mycorrhizal trees had been reduced. Saprotrophic fungi decreased in litter-removed stands.5. The changes of soil nitrogen properties and the biomass of Pleioblastus chino were studied for 3 years under the treatment of underlayer-mowing and litter-removal. Aboveground biomass was decreased by mowing. Belowground biomass was reduced by litter-removal. Total and mineral nitrogen content of topsoil was decreased under the treatments in the half-shade site. At the forest site, ammonium content was not changed, but nitrate content was decreased by mowing and litter-removal. Less
1.森林土壤中的交换性阳离子。增加了塔玛河沿岸城市化的推进。因此,城市地区的土壤酸度被中和了。研究了柳山次生林中土壤矿化和硝化作用与森林经营和微地形的关系。在坡顶,NH_4-N和NO_3-N浓度较高。边坡土壤NH4-N含量较高,NO3-N含量较低。在头穴中,硝态氮所占比例较高。森林采伐减少了土壤有机质供应,降低了土壤矿化速率。虽然也提高了硝化速率,但由于硝酸盐流出量增加,有利于硝酸盐的植物增多,导致矿质氮含量下降。根据林下植物区系的不同,将佐山山次生林的299个林分划分为7类。林分与天然林分之间发生了初级分离。二次分离发生…微地形类型中红色较多。矮秆竹优势林和欧亚优势林物种丰富度最低。对佐山山蘑菇的发生情况进行了为期3年的研究。外生菌根真菌以坡面较多,头穴较少。在外生菌根真菌中,鹅膏菌科和牛肝菌科在坡面上分布较多,而红菇科在坡面和头穴均有分布。林地外生菌根真菌减少,菌根树比例降低。腐生真菌在去除凋落物的林分中减少。通过连续3年的土壤氮素特性和毛竹生物量变化的研究,研究了覆膜割草和枯枝落叶清除处理对土壤氮素性质和生物量的影响。修剪降低了地上生物量。地下生物量通过清除枯枝落叶而减少。半遮荫处理降低了表层土壤全氮和矿质氮含量。在森林立地上,修剪和清除凋落物对土壤中的氨氮含量没有影响,但降低了硝酸盐含量。较少
