摘　　要：北京西郊白皮松、油松、柏树林下土壤动态研究试验林地的土壤为非石灰性半干润淋溶褐土。这类土壤在北京西郊高位平原区具有广泛的代表性。定位观测从1981年开始至1984年结束。研究结果表明:试验林地生长季节土壤水分含量保持在10～15 mm左右,属季节性淋溶型的半干润土壤水分状况,年平均土壤温度13℃,属温性土壤温度状况;土壤水分、土壤温度的季节性变化明显,年变化不明显。试验林地土壤养分状况的年、季节性动态不甚明显,不同林分间的年、季节性变化也不甚明显,但干湿季节分明,林木生长季节与雨季同期,因此土壤条件基本能保证白皮松、油松、柏树林分正常生长的需要。Permanent sample plots were located under plantations in the Western Suburb of Beijing. There are three plantation soil types for the sample plots: (1) eluvial cinnamon soil under Finns bungeana plantation; (2) eluvial cinnamon soil under Pinus tabulaeformis plantation; (3) eluvial cinnamon soil under Platycladus orientalis plantation.Observation began in 1981 and ended in 1984. It has been found that the soil moisture content of the experimental plantation field were 10~15 mm in growth season. It belongs to the sub-arid-wet soil moisture regime. Annual mean soil temperature .was 13℃, belongs to the temperate soil temperature regime. Seasonal variation of soil moisture and temperature were evident, annual variation (1981~1984) were not evident. Seasonal variation of soil CO2 content in the experimental plantation field were evident, but annual variation (1981~1984) were not evident. The variations of different stands in the experimental plantation fields were not evident enough.
