1.土壤是杉木生长发育的基础。为了闡明杉木生长发育与土壤条件的关系,以作为造林选地、林地土壤管理和土壤改良的努力方向,我們在会同、錦屏和江华林区进行了土壤的調查和定位研究。2.在总結羣众經驗的基础上,将調查地区杉木林地的土壤划分为4个类型7种土壤,卽黑沙土类型(黑油沙土和黑沙土)、黄泥土类型(黄泡土、黄泥土和黃沙土)、紅黄土类型(紅黄土)和石渣土类型(石渣土)。黑沙土类型有深厚肥沃带黑色的表土层(深40厘米以上,腐殖貭含量平均2—3%以上);黄泥土类型有中等深度和中等肥沃程度的表土层(深15—30厘米左右,腐殖貭含量平均2—3%);紅黄土类型表土較浅,且不很肥沃(深10厘米左右,腐殖貭含量平均2%左右);石渣土类型为薄层土壤,一般不用来栽培杉木。3.在不同的土壤上生长的杉木林分表現出不同的生长发育状况和生产力。在密度比較适当和幼林撫育比較及时的情况下,各种土壞上20年生杉木林分的平均树高、平均胸径和每亩蓄积大致如下:黑沙土类型分別为17—21米、17—20厘米和20—35立方米左右;黄泥土类型分别为11—15米、11—15厘米和12—20立方米左右;紅黄土类型分别为8—11米、8—11厘米和10—...

Neat and simple formulae for correcting tropospheric refraction effect aro presented in this paper. They can meet the needs of the positioning accuracy of the order of meter magnitude. At present time there are various models of the tropospheric refraotivity, in which the Hopfield's is the best, it is adopted here. In the satellite doppler positioning, the observations are discarded when the elevation of the satellite is under ten degrees. Thus the buckled parts of wave path do not effect on the positioning accuracy for the order of meter magnitude and then can be neglected.
