摘要
三明市区受工业污染严重,市郊国有林场经营区地处市区周山,培育抗污染的森林成为林场当务之急的工作。通过对12年生松荷混交林与松纯林进行比较,混交林的蓄积提高35.56%,飘尘量降低30.6%,其吸收有毒气体、减尘率、滞尘量、噪声减弱效果分别提高到40%、12.7%、22.5%和90.8%,在市区周山可推广营造松荷混交林。
Sanming City is heavily polluted by the industry. Sanming Suburb National Forest Farm surrounds Sanming City lying on the moutains. To cultivate the antipoUution forest is the urgence to the farm. Comparing to to pure forest Pinus massoniana, the 12-year-old mixed forest P. massoniana × S. superba increased 35.56% in its stand volume and decreased 30.6% in density of floating dust. The effects increased 40 % in absornbing poison gas, 12.7 % in the reducing dust rate, 22.5 % in reducing dust rate and 90.8% in stagnating the quantity of dust, and 90.8% in reducing the noise. Mixed forest P. massoniana × S. superba should be established on the moutains surrounding the city.
