| 摘 要： | 于2007～2010年生长季节,对侧柏、山杏、油松、柠条和山毛桃等林地土壤水分进行连续监测,并查阅相同树种和立地条件下的林分根系分布资料,以土壤水分对林木耗水满足程度作为评价指标,对半干旱黄土丘陵沟壑区小流域微地形条件下人工林对土壤水分的适宜性进行研究.结果显示:不同林分根系的垂直分布和土壤水分垂直变异相关性显著,水分...

| Abstract: | During the growth season of 2007～2010,continuous monitoring was conducted on forest soil moisture of Platycladus orientalis,Armeniaca sibirica,Pinus tabulaeformis,Caragana korshinskii and Prunus davidiana,and stand root distribution material of the same tree species in the same site conditions were consulted,taking soil moisture of forest tree satisfaction degree of water consumption as the evaluation index,meanwhile,the study was conducted on suitability of plantation on soil moisture under micro watershed topography in semi-arid loess hilly-gully region.The results showed: the vertical distribution of different stand root and soil moisture vertical variation had significant rela-tion,moisture conditions was better,root distribution density was bigger;during the growing season,suitability was low-er in May～June and October,suitability was higher in April,July～September;under the micro-topography conditions and artificial land preparation,soil moisture of small watershed had significant differences,but water environment was better,the growth of robust trees was better,so that did not show a suitability rule. |
