摘要
为改善半干旱区石质坡面立地条件,试验尝试了坑道式造林整地模式,并于2011年5—9月对其所产生的小气候效应进行了初步观测。结果表明:植苗点的坑道内较自然坡面(对照点)地面温度与地中温度在生长季有朝着利于林木成活与生长的方面转化趋势——在5月与9月温度高于对照,在6、7、8月低于对照;水面蒸发减少194.1mm,在半干旱地区这一变化趋势有利于林木成活与生长。
In order to improve the site conditions of rocky slope in semiarid area, trench afforestation model was tried microclimatic effects which were produced by trench afforestation model were preliminarily observed from May to September in 2011 ; result shows that： the earth surface temperature and the ground temperature of gallery lining of planting point in the growing season are conducive to the survival growth of trees than that on the natural slope （control point）：in May and September, temperature are higher than that of the control; in June, July and August, temperature are lower than that of the control;surface of the water evaporated decrease by 194.1 mm; this change is conducive to the survival growth of trees in semiarid areas.
