摘要:
通过研究黄土丘陵区油松人工林内空气温度和土壤温度的变化规律后认为，白天林内气温低于林外，夜间高于林外。晴天，林内外气温差异较大，阴天则较小；生长季林内平均气温高于林外，其最大差值出现在6月，最小差值出现在10月；林内气温梯度变化明显，日平均气温、日最高气温平均和日最低气温平均，林冠层中部均比林地表层和林冠表层大。林分和枯枝落叶层覆盖对土壤温度的影响主要表现在2个方面，即降低林内土壤温度和土壤温度的较差；日平均土壤温度，东坡较西北坡高0.48℃。
Abstract:
The variation laws of air temperature and soil temperature in artificial Chinese stands in loess hilly and gully region are studied, the results showed as follows. Air temperature in the stand is higher in daytime and lower in nighttime compared with the open field. The discrepancy of air temperature in the stand and open field is large in sunshine day and little in cloudy day. Mean air temperature of the growing season in the stand is higher than that in open field in which the biggest discrepancy value occurs in June and the smallest in October. Perpendicular variation of air temperature in the stands is obvious, mean, the highest mean and the lowest mean values of daily air temperature in the middle of canopy are higher than that on the surface of the canopy and in the 1.5 m height of the stand. The effects of the stands and litter layer on soil temperature result in the reduction of soil temperature and its amplitude. Daily mean soil temperature on eastern slope is 0.48℃ higher than that on northwestern slope.
