◇皆伐法 clear cutting method; 皆伐更新 regeneration under clear cutting; 皆伐林 clear cutting forest; 皆伐面积 clear-felled area; 皆伐区 clearing; 皆伐作业 clear cutting system
Examples
- The winter choice all cuts down the artificial regeneration mark to be higher than the selective felling artificial regeneration mark place
冬季选择皆伐人工更新迹地高于择伐人工更新迹地。 - And the clear - felling system of small area is put forward . the ecological function and productive force on evergreen broad - leave forest is reserached
并提出小面积皆伐的采伐方式,同时对常绿阔叶林的生态功能和生产力进行初步研究。 - And all cuts down the artificial regeneration mark in the selective felling artificial regeneration center , summer the panda choice selective felling artificial regeneration mark place ratio is higher than all cuts down the artificial regeneration mark place
在择伐人工更新和皆伐人工更新迹地中，夏季大熊猫选择择伐人工更新迹地的比率高于皆伐人工更新迹地。 - The conditions of its climate , moisture and soil are high quality . the mid - subtropical evergreen broad - leaved forest suffered the clear cutting fatally before 1950 ' s or in 1950 ' s . now the natural secondary evergreen broad - leaved forest grows well after half - century restoration
在上世纪五十年代(包括五十年代)以前，这片中亚热带常绿阔叶林遭受毁灭性的皆伐作业，现在生长着的是经过半个世纪恢复的天然次生中亚热带常绿阔叶林，长势良好。 - At the same time , the quality of different - state water was studied . the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth , specifically 0 . 74 > 0 . 94 andl . 34g / cm3 , the saturated , canaliculus and field moisture contents decrease gradually in layer a , b and c , accordingly the soil total foveola decreases gradually , and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space , which are respectively 0 . 92 and 0 . 99g / cm3 , and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
结果表明：冷杉原始森林土壤容重随土层深度的增加而增大，分别为0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ，饱和持水量、毛管持水量、田间持水量a层、 b层、 c层逐渐减小，十壤总孔隙度也逐渐减小，土壤的持水能力随深度的增加逐渐减弱；林外空地a层、 b层十壤容重相差不人，分别为0 . 92和0 . 99g cm ~ 3 ，其它规律与林内人体相同：皆伐迹地的低洼地段容易发生逆行演替，形成高原沼泽地。
